[Platinum.fund] (https://platinum.fund/sto/)
We also created the UBAI, the unique educational project with the best and most useful online courses. We not only share our knowledge but also help the best graduates to find a job! After finishing our courses you will know all about crypto securities, ICO and STO advertizing and best blockchain platforms.
What a Blockchain Wallet is? What is its purpose?
Find the answer after reading this article.
Public/Private Key
The public key is the digital code you give to someone that wants to transfer ownership of a unit of cryptocurrency to you; and a private key is what you need to be able to unlock your own wallet to transfer a unit of a cryptocurrency to someone else. The encoding of information within a wallet is done by the private and public keys. That is the main component of the encryption that maintains the security of the wallet. Both keys function in simultaneous encryption systems called symmetric and asymmetric encryption. The former, alternatively known as private key encryption, makes use of the same key for encryption and decryption. The latter, asymmetric encryption, utilizes two keys, the public and private key, wherein a message-sender encrypts the message with the public key, and the recipient decodes it with their private key. The public key uses asymmetric algorithms that convert messages into an unreadable format. A person who possesses a public key can encrypt the message for a specific receiver.
Accessing wallets
Methods of wallet access vary depending on the type of wallet being used. Various types of currency wallets on an exchange will normally be accessed via the exchange’s entrance portal, normally involving a combination of a username/password and optionally, 2FA (Two factor authentication, which we explain in more detail later). Whereas hardware wallets need to be connected to an internet enabled device, and then have a pin code entered manually by the user in possession of the hardware wallet in order for access to be gained. Phone wallets are accessed through the device on which the wallet application has been downloaded. Ordinarily, a passcode and/or security pattern must be entered before entry is granted, in addition to 2FA for withdrawals.
Satoshi Nakamoto built the Satoshi client which evolved into Bitcoin in 2009. This software allowed users to create wallets and send money to other addresses. However, it proved to be a nightmarish user experience, with many transactions being sent to incorrect addresses and private keys being lost. The MtGox (Magic the Gathering Online exchange, named after the original intended use of the exchange) incident, which will be covered in greater detail later, serves as a reminder of the dangers present in the cryptosphere regarding security, and the need to constantly upgrade your defenses against all potential hacks. The resulting loss of 850k BTC is a still unresolved problem, weighing heavily on the victims and the markets at large. This caused a huge push for a constantly evolving and improving focus on security. Exchanges that developed later, and are thus considered more legitimate and secure, such as Gemini and Coinbase, put a much greater emphasis on vigilance as a direct result of the MtGox hacking incident. We also saw the evolution of wallet security into the physical realm with the creation of hardware wallets, most notable among them the Ledger and Trezor wallets.
Types of Wallets & Storage Methods
The simplest way to sift through the dozens of cryptocurrency storage methods available today, is to divide them up into digital and non-digital, software and hardware wallets. There are also less commonly used methods of storage of private keys, like paper wallets and brain wallets. We will examine them all at least briefly, because in the course of your interaction with cryptocurrencies and Blockchain technology, it is essential to master all the different types of hardware and software wallets. Another distinction must be made between hot wallets and cold wallets. A hot wallet is one that is connected to the internet, and a cold wallet is one that is not. Fun fact: The level below cold storage, deep cold storage has just recently been implemented by the Regal RA DMCC, a subsidiary of an internationally renowned gold trading company licensed in the Middle East. After having been granted a crypto trading license, Regal RA launched their “deep cold” storage solution for traders and investors, which offers the ability to store crypto assets in vaults deep below the Almas Tower in Dubai. This storage method is so secure that at no point is the vault connected to a network or the internet; meaning the owners of the assets can be sure that the private keys are known only to the rightful owners.
Lets take a quick look at specific features and functionality of varieties of crypto wallets. Software wallets: wallet applications installed on a laptop, desktop, phone or tablet. Web Wallets: A hot wallet by definition. Web Wallets are accessible through the web browser on your phone or computer. The most important feature to recognize about any kind of web wallet, is that the private keys are held and managed by a trusted third party. MyEtherWallet is the most commonly used non-exchange web wallet, but it can only be used to store Ethereum and ERC-20 tokens.
Though the avenue of access to MEW is through the web, it is not strictly speaking a web wallet, though this label will suffice for the time being. The MEW site gives you the ability to create a new wallet so you can store your ETH yourself. All the data is created and stored on your CPU rather than their servers. This makes MEW a hybrid kind of web wallet and desktop wallet. Exchange Wallets: A form of Web Wallet contained within an exchange. An exchange will hold a wallet for each individual variety of cryptocurrency you hold on that exchange. Desktop Wallets: A software program downloaded onto your computer or tablet hard drive that usually holds only one kind of cryptocurrency. The Nano Wallet (Formerly Raiwallet) and Neon wallet for storage of NEO and NEP-5 tokens are notable examples of desktop wallets Phone Wallets: These are apps downloaded onto a mobile phone that function in the same manner as a desktop wallet, but actually can hold many different kinds of cryptocurrency. The Eidoo Wallet for storing Ethereum and its associated tokens and Blockchain Wallet which currently is configured to hold BTC, ETH and Bitcoin Cash, are some of the most widely used examples.
Hardware wallets — LedgeTrezoAlternatives
Hardware wallets are basically physical pathways and keys to the unique location of your crypto assets on the Blockchain. These are thought to be more secure than any variety of web wallet because the private key is stored within your own hard wallet, an actual physical device. This forcibly removes the risk your online wallet, or your exchange counter party, might be hacked in the same manner as MtGox. In hardware wallet transactions, the wallet’s API creates the transaction when a user requests a payment. An API is a set of functions that facilitates the creation of applications that interact and access features or data of an operating system. The hardware then signs the transaction, and produces a public key, which is given to the network. This means the signing keys never leave the hardware wallet. The user must both enter a personal identification number and physically press buttons on the hardware wallet in order to gain access to their Blockchain wallet address through this method, and do the same to initiate transfers.
Paper Wallets
Possibly the safest form of cryptocurrency storage in terms of avoiding hacking, Paper Wallets are an offline form of crypto storage that is free to set up, and probably the most secure way for users, from beginners to experts, to hold on to their crypto assets. To say it simply, paper wallets are an offline cold storage method of storing cryptocurrency. This includes actually printing out your public and private keys on a piece of paper, which you then store and save in a secure place. The keys are printed in the form of QR codes which you can scan in the future for all your transactions. The reason why it is so safe is that it gives complete control to you, the user. You do not need to worry about the security or condition of a piece of hardware, nor do you have to worry about hackers on the net, or any other piece of malware. You just need to take care of one piece of paper!
Real World Historical Examples of Different Wallet Types
Web Wallet: Blockchain.info Brief mechanism & Security Blockchain.info is both a cryptocurrency wallet, supporting Bitcoin, Ethereum and Bitcoin cash, and also a block explorer service. The wallet service provided by blockchain.info has both a Web Wallet, and mobile phone application wallet, both of which involve signing up with an email address, and both have downloadable private keys. Two Factor Authentication is enabled for transfers from the web and mobile wallets, as well as email confirmation (as with most withdrawals from exchanges). Phone Wallet: Eidoo The Eidoo wallet is a multi-currency mobile phone app wallet for storage of Ethereum and ERC-20 tokens. The security level is the standard phone wallet level of email registration, confirmation, password login, and 2 factor authentication used in all transfers out. You may find small volumes of different varieties of cryptocurrencies randomly turning up in your Eidoo wallet address. Certain projects have deals with individual wallets to allow for “airdrops” to take place of a particular token into the wallet, without the consent of the wallet holder. There is no need to be alarmed, and the security of the wallet is not in any way compromised by these airdrops.
Neon Wallet
The NEON wallet sets the standard for web wallets in terms of security and user-friendly functionality. This wallet is only designed for storing NEO, Gas, and NEP-5 tokens (Ontology, Deep Brain Chain, RPX etc.). As with all single-currency wallets, be forewarned, if you send the wrong cryptocurrency type to a wallet for which it is not designed, you will probably lose your tokens or coins. MyEtherWallet My Ether Wallet, often referred to as MEW, is the most widely used and highly regarded wallet for Ethereum and its related ERC-20 tokens. You can access your MEW account with a hardware wallet, or a different program. Or you can also get access by typing or copying in your private key. However, you should understand this method is the least safe way possible,and therefore is the most likely to result in a hack. Hardware: TrezoLedger Brief History Mechanism and Security A hardware wallet is a physical key to your on-chain wallet location, with the private keys contained within a secure sector of the device. Your private key never leaves your hardware wallet. This is one of the safest possible methods of access to your crypto assets. Many people feel like the hardware wallet strikes the right balance between security, peace of mind, and convenience. Paper Wallet Paper wallets can be generated at various websites, such as https://bitcoinpaperwallet.com/ and https://walletgenerator.net/. They enable wallet holders to store their private keys totally offline, in as secure a manner as is possible.
Real World Example — Poor Practices
MtGox Hack history effects and security considerations MtGox was the largest cryptocurrency exchange in the world before it was hacked in 2014. They were handling over 70% of BTC transactions before they were forced to liquidate their business. The biggest theft of cryptocurrency in history began when the private keys for the hot wallets were stolen in 2011 from a wallet.dat file, possibly by hacking, possibly by a rogue employee. Over the course of the next 3 years the hot wallets were emptied of approximately 650000 BTC. The hacker only needed wallet.dat file to access and make transfers from the hot wallet, as wallet encryption was only in operation from the time of the Bitcoin 0.4.0 release on Sept 23rd 2011. Even as the wallets were being emptied, the employees at Mt Gox were apparently oblivious to what was taking place. It seems that Mt Gox workers were interpreting these withdrawals as large transfers being made to more secure wallets. The former CEO of the exchange, Mark Karpeles, is currently on trial for embezzlement and faces up to 5 years in prison if found guilty. The Mt Gox hack precipitated the acceleration of security improvements on other exchanges, for wallets, and the architecture of bitcoin itself. As a rule of thumb, no small-to-medium scale crypto holders should use exchange wallets as a long-term storage solution. Investors and experienced traders may do this to take advantage of market fluctuations, but exchange wallets are perhaps the most prone to hacking, and storing assets on exchanges for an extended time is one of the riskiest ways to hold your assets.
In a case strikingly similar to the MtGox of 2011–2014, the operators of the BitGrail exchange “discovered” that approximately 17 million XRB ($195 million worth in early 2018) were missing. The operators of the exchange were inexplicably still accepting deposits, long after they knew about the hack. Then they proceeded to block withdrawals from non-EU users. And then they even requested a hard fork of the code to restore the funds. This would have meant the entire XRB Blockchain would have had to accept all transactions from their first “invalid” transaction that were invalid, and rollback the ledger. The BitGrailexchange attempted to open operations in May 2018 but was immediately forced to close by order of the Italian courts. BitGrail did not institute mandatory KYC (Know your customer) procedures for their clients until after the theft had been reported, and allegedly months after the hack was visible. They also did not have 2 factor authentication mandatory for withdrawals. All big, and very costly mistakes.
Case Study: Good Practice Binance, the Attempted Hack
During the 2017 bull run, China-based exchange Binance quickly rose to the status of biggest altcoin exchange in the world, boasting daily volumes that surged to over $4 billion per day in late December. Unfortunately, this success attracted the attention of some crafty hackers. These hackers purchased domain names that were confusingly similar to “binance.com”. And then they created sufficiently convincing replica websites so they could phish traders for their login information. After obtaining this vital info, the scammers created API keys to place large buy orders for VIAcoin, an obscure, low volume digital currency. Those large buy orders spiked VIA’s price. Within minutes they traded the artificially high-priced VIA for BTC. Then they immediately made withdrawal requests from the hacked BTC wallets to wallets outside of the exchange. Almost a perfect fait accompli! But, Binance’s “automating risk management system” kicked in, as it should, and all withdrawals were temporarily suspended, resulting in a foiled hacking attempt.
Software Wallets Web/Desktop/Phone/Exchange Advantages and Limitations
As we said before, it is inadvisable to store crypto assets in exchange wallets, and, to a lesser extent, Web Wallets. The specific reason we say that is because you need to deliver your private keys into the hands of another party, and rely on that website or exchange to keep your private key, and thus your assets, safe. The advantages of the less-secure exchange or web wallets, are the speed at which you can transfer assets into another currency, or into another exchange for sale or for arbitrage purposes. Despite the convenience factor, all software wallets will at some point have been connected to the internet or a network. So, you can never be 100% sure that your system has not been infected with malware, or some kind of keylogging software, that will allow a third party to record your passwords or private keys. How well the type of storage method limits your contact with such hazards is a good way to rate the security of said variety of wallet. Of all the software wallets, desktop and mobile wallets are the most secure because you download and store your own private key, preferably on a different system. By taking the responsibility of private key storage you can be sure that only one person has possession of it, and that is you! Thereby greatly increasing the security of your crypto assets. By having their assets in a desktop wallet, traders can guard their private key and enjoy the associated heightened security levels, as well keep their assets just one swift transfer away from an exchange.
Hardware Wallets Advantages and Limitations
We briefly touched on the features and operation of the two most popular hardware wallets currently on the market, the Ledger and Trezor wallets. Now it will be helpful to take a closer look into the pros and cons of the hardware wallet storage method. With hardware wallets, the private keys are stored within a protected area of the microcontroller, and they are prevented from being exported out of the device in plain text. They are fortified with state-of-the-art cryptography that makes them immune to computer viruses and malware. And much of the time, the software is open source, which allows user validation of the entire performance of the device. The advantages of a hardware wallet over the perhaps more secure paper wallet method of crypto storage is the interactive user experience, and also the fact that the private key must at some stage be downloaded in order to use the paper wallet. The main disadvantage of a hardware wallet is the time-consuming extra steps needed to transfer funds out of this mode of storage to an exchange, which could conceivably result in some traders missing out on profits. But with security being the main concern of the vast majority of holders, investors and traders too, this slight drawback is largely inconsequential in most situations.
Paper Wallets Advantages and Limitations
Paper wallets are thought by some to be the safest way to store your crypto assets, or more specifically, the best method of guarding the pathways to your assets on the Blockchain. By printing out your private key information, the route to your assets on the Blockchain is stored 100% offline (apart from the act of printing the private key out, the entire process is totally offline). This means that you will not run the risk of being infected with malware or become the victim of keylogging scams. The main drawback of using paper wallets is that you are in effect putting all your eggs in one basket, and if the physical document is destroyed, you will lose access to your crypto assets forever.
Key things to keep in mind about your Wallet Security: Recovery Phrases/Private Key Storage/2FA/Email Security
Recovery phrases are used to recover the on-chain location for your wallet with your assets for hardware wallets like ledgers and Trezors that have been lost. When you purchase a new ledger for example, you just have to set it up again by entering the recovery phrase into the display and the lost wallets will appear with your assets intact. Private key storage is of paramount importance to maintain the safety of your on-chain assets! This should be done in paper wallet form, or stored offline on a different computer, or USB device, from the one you would typically use to connect to the 2 Factor Authentication (2FA) sometimes known as “two step authentication”. This feature offers an extra security layer when withdrawing funds from cryptocurrency wallets. A specialized app, most commonly Google Authenticator, is synced up to the exchange to provide a constantly changing code. This code must be entered within a short time window to initiate transfers, or to log into an exchange, if it has also been enabled for that purpose.
You must always consider the level of fees, or the amount of Gas, that will be needed to carry out the transaction. In times of high network activity Gas prices can be quite high. In fact, in December 2017 network fees became so high that some Bitcoin transactions became absolutely unfeasible. But that was basically due to the anomalous network congestion caused by frantic trading of Bitcoin as it was skyrocketing in value. When copying wallet addresses, double check and triple check that they are correct. If you make a mistake and enter an incorrect address, it is most likely your funds will be irretrievably lost; you will never see those particular assets again. Also check that you haven’t input the address of another one of your wallets that is designed to hold a different variety of cryptocurrency. You would similarly run the very great risk of losing your funds forever. Or, at the very least, if you have sent the wrong crypto to a large exchange wallet, for example on Coinbase, maybe you could eventually get those funds back, but it would still entail a long and unenjoyable wait.
How to Monitor Funds
There are two ways to monitor you funds and your wallets. The first is by searching for individual wallet addresses on websites specifically designed to let you view all the transactions on a particular Blockchain. The other is to store a copy of your wallet contents on an application that tracks the prices of all cryptocurrencies. Blockchain.info is the block explorer for Bitcoin, and it allows you to track all wallet movements so you can view your holdings and all the historical transactions within the wallet. The Ethereum blockchain’s block explorer is called Ether scanner, and it functions in the same way. There is a rival to Ether scanner produced by the Jibrel Network, called JSearch which will be released soon. JSearch will aim to offer a more streamlined and faster search method for Ethereum blockchain transactions. There are many different kinds of block explorer for each individual crypto currency, including nanoexplorer.io for Nano (formerly Rai Blocks) and Neotracker for NEO. If you simply want to view the value of your portfolio, the Delta and Blockfolio apps allow you to easily do that. But they are not actually linked to your specific wallet address, they just show price movements and total value of the coins you want to monitor.
That’s not all! You can learn how to transfer and monitor the funds in and out of your wallet by clicking on the link.

A Brief History of People Losing their Cryptocurrency

A Brief History of People Losing their Cryptocurrency
The history of cryptocurrency is fraught with people losing their coins, whether through carelessness, greed, bad luck, or some combination of the above. Some ignored the first rule of crypto: “never leave your crypto on an exchange.” When their exchange failed, their crypto went with it. Others were negligent with their storage solutions, misplacing old hard drives, using software wallets on malware-ridden PCs, forgetting the passwords to hardware wallets. Some were greedy and lost their coins to a Nigerian Crypto Prince or a Ponzi scheme. And some were just plain unlucky. These unfortunate tales remind us to be careful with our crypto, and underscore the need for new solutions to storing crypto safely.
Buying cryptocurrency used to be a risky prospect. There weren’t many exchanges, they often required you to deposit fiat via a third party, you certainly couldn’t use your credit card, and there was hardly any regulation. It was considered unwise to leave your cryptocurrency on the exchange after you bought it. Many people today feel safe buying some crypto on Coinbase or Binance, without transferring it to a personal wallet, but in those wild years you absolutely wanted control of your private keys. If the exchange had the keys, you were trusting your crypto to the reputation of a small company, located who-knows-where, that made its revenue by exchanging speculative, unregulated digital currencies between anonymous traders. One such company was Mt. Gox.
Mt Gox was a Tokyo based Bitcoin exchange. Led by CEO Mark Karpelès, who was also majority shareholder and lead developer, Mt Gox expanded quickly. Founded in 2010 and bought by Karpelès in 2011, Mt. Gox quickly dominated the Bitcoin market, responsible for 70% of BTC volume in 2013, with 1.1 million active accounts. But despite the outwards success, there were some signs that all was not well internally. Karpelès refused to allow any updates to the exchange software, without approving changes to the source code, meaning needed updates could languish for weeks. In June, 2011 the exchange lost $8.75 million in Bitcoin to a cyberattack, and the site went offline. According to friends of Karpelès who flew in to help get Mt. Gox back online, Karpelès seemed surprisingly relaxed about the affair, even taking the weekend off.
Mt. Gox was brought back online, but soon after US Federal agents seized $5 million from the company’s US account, and former business partner CoinLab sued for $75 million. Karpelès seemed more focused on creating a Bitcoin Cafe in the Mt. Gox building than on addressing these many issues. After an internal memo was leaked disclosing the disappearance of 850,000 BTC (worth about $460 million at the time), Mt. Gox collapsed into bankruptcy. It is still in bankruptcy proceedings today.

One might be tempted to dismiss the failure of Mt. Gox as a lesson learned by the crypto community, a mistake that wouldn’t be repeated. Sadly, exchanges continue to lose their customers’ crypto with startling regularity. A less spectacular but much more recent loss was $150 million of Nano stolen from exchange Bitgrail in February. Bitgrail’s management blamed the Nano blockchain software for the theft, but has refused to release any evidence. Nano, for its part, has vigorously defended itself against Bitgrail’s claims, showing that the missing Nano was stored in a hot wallet (one that is accessible online) instead of a cold wallet, which would have been more protected. Whoever’s to blame, if you had Nano on Bitgrail, it’s gone. Similarly, if you had any crypto on Korean exchange Youbit, you’re down 17%, which was stolen in a hack in December. Or if you used Bitconnect, you’ll find your Bitconnect tokens became nearly worthless after the company shuttered in January.

“Dozens of exchanges have failed since the creation of Bitcoin, taking many small fortunes with them. This should serve as a reminder to never leave your cryptocurrency on an exchange; however there are other ways to lose your coins,” according to Saifu co-founder Evgeny Vigovsky.
In October of 2017, a new cryptocurrency was created called Bitcoin Gold. Bitcoin Gold is a fork of the Bitcoin blockchain. This meant that anyone who owned Bitcoin was now entitled to an equivalent amount of Bitcoin Gold. Many were eager to claim their share, and some found a Bitcoin Gold online wallet called mybtgwallet.com. This helpful site offered to assist users claim their Bitcoin Gold, instructing them to enter their wallet’s seed or private key. The seed is a series of words, usually 24, that can be used to recreate a wallet if it’s lost or corrupted. Giving someone your wallet seed or private keys is akin to giving them the keys to your safe deposit box, and the victims of mybtgwallet found their wallets were quickly emptied of whatever cryptocurrencies they held. More than $3 million in Bitcoin was stolen.
https://preview.redd.it/e5btpnfunj611.png?width=800&format=png&auto=webp&s=e2fa9a011de23e4f223d815567b061e3d2bc7625
MyEtherWallet is a popular online wallet for Ethereum and other tokens built on the Ethereum blockchain. The wallet is free to use, and as far as online wallets go, it’s secure, requiring users to take steps to protect themselves. In December, the MyEtherWallet iOS app hit the #3 spot on the App Store in the finance category. Unfortunately for the thousands of users who bought the app for $4.99, this app was just another scam. MyEtherWallet doesn’t have an app (and Apple doesn’t allow wallet apps on the App Store). Suspicious users alerted the MyEtherWallet team, who alerted Apple. Two days later, Apple responded and removed the app from the app store.
https://preview.redd.it/jcokfj6ynj611.png?width=519&format=png&auto=webp&s=903ea36e5e749a1854ae8fcacabc19032276ed04
Less colorful but more insidious, there are a plethora of malware that targets cryptocurrency wallets. These programs run quietly in the background, searching for wallet software on your computer and uploading your credentials. A particularly nasty bit of malware was the Pony botnet, discovered in September 2014. The Pony botnet used a trojan virus to compromise about 700,000 accounts, including email accounts, website login credentials, and other sensitive information. Bitcoin totalling 335 were stolen from 85 different wallets; those Bitcoin are worth about $2.7 million today.
Some classic scams have been updated for cryptocurrencies, including a variation on the Nigerian prince con, harnessing social media to attract victims. In the classic Nigerian prince scam, the victim would receive an email from a Nigerian prince who needs help to move his wealth to the United States. The prince needs someone to deposit a check for him, then wire out the funds. They pay the wire fee but get to keep part of the funds from the deposited check. Typically the victim’s bank informs them that they’ve deposited a bad check well after they’ve wired out the funds for the “Prince.”
In the new variation, scammers impersonate well-known figures of the tech world like Elon Musk or John McAfee, often on Twitter. They use a name similar to the celebrity, and their picture. They claim to be giving away cryptocurrency to the first 100 people to respond to the tweet, but there’s a catch; respondents need to send a small amount of crypto to pay for the “fees.” Naturally, the scammer just keeps these small bits of crypto and does not send anything in return. Here’s “Elon Msk” giving away some free Bitcoin:
https://preview.redd.it/jwasx3v3oj611.png?width=622&format=png&auto=webp&s=d1a9da3a2cc9859527e3b7939c61c61428a71a85
Thankfully, crypto security is steadily improving. The rise in value and mainstream adoption have attracted established cybersecurity players, and innovative new storage solutions are being created with increasing frequency. Our firm Saifu has developed its own crypto storage hardware in partnership with Thales. “Users’ crypto keys are stored in Thales hardware security modules, which cannot be accessed remotely. Even if we were ever hacked, our customers’ cryptocurrencies are protected. As it becomes safer and easier to buy and use cryptocurrencies, we believe mainstream adoption will skyrocket. The crypto revolution is just beginning,” Vigovsky, the Saifu co-founder, says.

Beginners Guide To Using Binance (Buying ALTcoins)

Hello, Today I am going to give you newcomers a walkthrough on how to setup and use Binance.
  • First you may ask.. What is Binance??
    Binance is a Cryptocurrency Exchange that focuses on Crypto-to-Crypto Trading. Which means that unlike other exchanges that exchange "Fiat" or Traditional Currencies (USD,EUR,etc.) for Cryptocurrencies, you would instead exchange your Bitcoin or Ethereum for Lesser Known ALTcoins and Vice-versa. Binance is a quick and easy way to get into ALT coins if you already own some Cryptocurrencies, and don't worry, you don't have to keep your coins on the exchange, it allows you to send your individual ALT coins to your personal wallets and secure them.
Lets Get Started...

STEP 1 - Preparing your Computer for Cryptocurrency Transactions

This is a step most people do not think about. I have been reading more and more about MalWare,Spyware and keyloggers that are specifically targeting Cryptocurrency transactions. If your computer is infected, you could easily lose your cryptos before you even get started. Do some virus scans, malware scans and make sure your antivirus is up to date. I can not stress this enough, make sure your computer is secure before you begin trading cryptos.

STEP 2 - Registration

Once you have a secure PC for setting up your account, you will want to go to Binance.com. Here is a SCREENSHOT of what you will see when you first go to the Binance Website. Make sure when visiting the binance website you check the lock symbol in the address bar too make sure your at the correct URL and that the site is Secure. Registering is simple. Enter the Email and Password you would like to use and hit register. You will receive an email with a verification link, once you verify your email, your account will be registered.

STEP 3 - 2FA (Two-Factor Authentication)

When you first login you should be greeted by this SCREEN. Depending on how secure you want your account to be, I highly suggest you enable Two-Factor Authentication. What 2FA does is creates a random 6 digit number that changes every 30 seconds. You will also need this code on top of your email and password to login. So if someone does somehow manage to steal your password, you will still be safe as long as they do not have your 2FA device. The only option available is by Google Authenticator which is available for both Android and iOS Smartphones.
Once your ready to begin click the Google Auth Button and it will bring up this SCREEN
  • Download the Google Authenticator App on your smartphone/tablet. You will see a + symbol in the upper right corner of the screen. Choose the "Scan Barcode" option and scan the 2FA Backup Key. It should now list a 6-digit number and show binance.com and your email. This code will change every 30 seconds. Make sure you back up your 2FA code (secret key) and keep it for safe keeping. DO THIS BEFORE you enter your login password and 2FA code from the app in the right hand side of the screen. Once you have entered both your password and current 2FA code from the app, 2FA will be enabled. Once you have your account setup, secured, and you have backed up your 2FA barcode, your ready to make a deposit.

STEP 4 - Making a deposit

  • In order to start trading or buying ALTcoins you are going to have to fund your account. Hover your mouse over the "funds" tab and click on "Deposits and Withdrawals" Here's a screenshot
  • You are going to be met with a wall of different coins. Type in the search bar in the top left the coin you want to deposit. Binance uses two main pairs for trading. Bitcoin (BTC) or Ethereum (ETH). Lets use Bitcoin in this example since it is the most popular, although, at the moment it is quite expensive to send and receive.
  • Type "Bitcoin" into the search bar in the top left hand side of the Deposits and Withdrawals Screen and click on deposit. You will be now see a screen that has a Bitcoin Wallet Address. This is your Binance Bitcoin Wallet and is the address you want to send your bitcoins in order to trade them for other coins. You simply send your Bitcoins from your wallet to your Binance Bitcoin Wallet the same way you would make any other bitcoin transaction. You can check the transaction by going to "History" which is under the "Funds" tab, or by checking the wallet address on a Block Chain explorer. Once you get your first confirmation it will show up in the history tab and you will receive an email notifying you that your account has been funded.

STEP 5 - Trading

Before you buy your first coins you will want to grab yourself a few Binance Coins or BNB to pay for trading fees. In order to take advantage of the 0.05% trading fees you will need have some BNB. If your only doing small trades, I suggest just buying 1 or 2 BNB to get a feel of how much each trade costs. One of the main reasons to do this is because binance does not allow you to trade in small decimals, so if it ends up taking your fees from the coins your trying to buy, you will be left with untradeable dust. Say you buy 110 XRP and do not have any BNB to pay for the fees. Your fees will now be 1% of the total amount or 1.1 XRP. So you will have 108.9 XRP and will be unable to trade the 0.9 XRP back to Bitcoin or Ethereum. This 0.9 XRP is considered "Dust". Binance is apparently working on a solution to this. Buying BNB is easy. From the Exchange Screen find the BNB/BTC pair (if you deposited Bitcoin) and place a market order to buy some BNB. The method will be the exact same as shown below.
Once you have some Bitcoin or Ethereum loaded into your account your now ready to trade it for other coins. I'm assuming at this point you have done your research and know the coins you want to get into. In this example we are going to use a popular cryptocurrency called XRP or Ripple. Hit the "Exchange" Button on the top left of your screen and go to basic. It will bring up a screen with charts and a bunch of green and red numbers. HERES AN EXAMPLE
There are two types of orders you can make:
  • Market Order - A Market Order is simply buying it at the current "ASK" or market price. This is the simplest order as it doesn't involve any thinking. Just enter the amount of coins you want to buy and press the big green "BUY" button. Once the order goes through you will see the coins you bought in your available balance.
  • Limit Order - A Limit Order is where you can set your own BUY price. Say you think it will go down a bit before it goes up, so you set your limit order a bit lower then the current price in hopes of getting a discount. The prices you see on the chart shows the current price of the coin in relation to the Bitcoin (BTC). Be aware that it will only trigger and make the buy if it hits the price you set in your limit order.
If you want to sell your ALTcoins back to Bitcoin or Ethereum then place a market sell order or limit order at the price you want to convert them back.

STEP 6 - Securing your new coins

Depending on if your strategy is too buy and hold, Once you buy your coins you will want to secure them by sending them to the individual wallet made for the coin you bought. In our case we just bought Ripple XRP. So you go back to your "Deposits and Withdrawals" under the "Funds" tab in binance and type in the search bar the coin you want to send out.
Make sure you have the right coin and hit the "Withdrawal" button. You will be brought to a screen where it wants you to enter your wallet address. Here is an example from the "Toast" website Your address would be the string of random letter and numbers above the barcode. Copy and Paste this into the address bad where I labeled "Your Address Here" USE THIS SCREENSHOT AS A REFERENCE Any withdrawal transaction will also be recorded under "History" under the "Funds" tab. Your coins should now show up in your toast wallet.
Be sure when you are researching a coin to buy to also do some research on what wallets are available and how secure they are. Although there are multi-currency wallets, typically you will have 1 wallet for each different coin.

[uncensored-r/CryptoCurrency] Why you should be voting to support Elastos on the Binance Community Vote

The following post by Blazarius120 is being replicated because the post has been silently removed and some comments within it have been openly removed.
The original post can be found(in censored form) at this link:
np.reddit.com/ CryptoCurrency/comments/7zsfgh
The original post's content was as follows:
Elastos project needs your help. Partnership with NEO and Bitmain. 17 years in development. 4 million lines of code.
For the sake of the market, vote for it on the Binance community vote, it has the potential to activate a market bull run. Check the 24 hour volume and its trading on 1 exchange.
Upvote please for transparency.
What is Elastos?
Elastos is the world’s first internet operating system that uses the internet as the base-layer infrastructure rather than an application. Elastos prohibits application programs from directly accessing the network in order to eliminate most viruses and attacks(especially DDoS attacks) on the internet. According to Elastos, network communication should be separated from application computing. Elastos is building a truly decentralized Smart Web powered by blockchain implementing P2P economic infrastructure while also providing digital asset ownership and management through smart contracts.
Brief Summary?
Bitcoin = Trustworthy Ledger
Ethereum = Trustworthy Ledger + Smart Contracts
Elastos = Trustworthy Ledger + Smart Contracts + Monetizable Dapps and Digital Assets
Development History(Tens of Millions of Open-Source Code spanning Decades)
In 2000, Rong Chen a Tsinghua alumni left Microsoft and returned to China to start his business.
In 2003, Rong Chen was received by Jin-Tao Hu, the former CPC General Secretary.
In 2013, Foxconn funded Elastos with 200 million RMB.
In 2017, Sunny Feng Han and Ji-Han Wu started running the Bitcoin Investment Elastos Blockchain Community and founded G3 with Bitmain and NEO.
In 2017, the Elastos Blockchain community received a global digital token investment worth 600 million RMB.
What is the Elastos Blockchain structure?
Elastos blockchain works as a trust zone for the entire network operating system that applies main and sidechain solutions to facilitate the smart economy and a healthy decentralized application environment. This means that every application built on Elastos can create individual sidechains that is thoroughly customizable, allowing clients to pick a different consensus method depending on the use case. The structure of main chain and side chain avoids main chain being overloaded and leads to easy routing and flexible extension, increasing the possibility for Elastos to be largely scalable.
Elastos implements merged mining with bitcoin. This strategy saves resources and avoids repeated consumption. Miner submits Proof-of-Work(PoW) to both bitcoin and elastos and enjoys profits of mining competition without extra consumption of computing power. The consensus mechanism for Elastos is AuxPoW+DPoS where the mining reward distribution is 35% for AuxPoW, 35% for DPoS, 20% for Ecosystem Application Reward and 10% for Foundation Running and Development. Tokens for apps built on Elastos can be published on sidechains. These tokens may participate in two-way asset transfer across the main chain and side chains.
What is the business model for Elastos?
Provide large blockchain applications with secure running environment
Digital content remains intact after multiple uses
Big data and digital content can identify ownership on blockchain and correspond to tokens
Tokens can be transferred and traded legally on blockchain, realizing future capital
Usage of tokens can consume/use digital content in Elastos Runtime.
Elastos can set a fixed limited amount for digital assets, thereby creating scarcity of valued products
Example of how the above works?
Content creators create 500 copies of limited edition games built on top of Elastos
Users buy these limited copies
They then play these games in Elastos Runtime on their cell phones, desktop computers, game consoles, etc.
Holders of these limited edition games then resell them to other people. Because this game is of limited edition, it fluctuates in the second-hand market. It helps users enjoy the digital content, earn the early benefits and earn some by reselling it, thereby transferring the ownership to other people.
Ethereum v Elastos?
Ethereum: Single mainchain structure leads to the upper limit of computing power and extensibility. Elastos: Proposes to adopt a flexible main chain and sidechain blockchain design structure. The main chain is only responsible for basic transactions and payments while the sidechain executes smart contracts to support various applications and services.
Ethereum: As storage and computing space, blockchain is not able to support user daily life scenarios and not able to support digital content(eg. Cryptokitties). Elastos runs applications on elastos runtime as opposed to the already congested blockchain. This method is more secure. All network data must be sent through a trustable and verifiable channel. Identification and authentication come from the blockchain ID. This way, the blockchain’s credibility can be transferred to Elastos Runtime. Elastos Runtime can have various forms: an independent OS, a virtual machine, or a software development kit(SDK) that integrates into native apps of other mainstream operating systems.
EOS v Elastos?
EOS: Is a blockchain OS, but its development period and open source codes are much shorter than Elastos’ 17 years. Elastos has released more than 4 million lines of code to github and plans to release 10+ million lines of code in total(contributing to the open source community).
EOS is dependent on its main-chain, so no matter how optimized it becomes, its throughput is limited. Elastos can extend the throughput infinitely with flexible main-chain and side-chain solution. Also, Elastos Runtime can deliver the trust function of the blockchain to a user’s application(like a cell phone, laptop, etc) which applies the blockchain to various scenarios in daily life.
EOS, through the adoption of the DPoS consensus mechanism, can realize high throughput rate. Elastos computation bandwidth is distributed according to the number of tokens held. It refers to the design philosophy of time sliced distribution in the traditional multi-task operating system and encourages the community to hold tokens. The main-chain design focuses on improving extensibility for smooth access to sidechain. The consensus mechanism on the sidechain can be anything(from DPoS to DBFT to anything else)
EOS runs everything utilizing main chain for everything. Elastos: Services on the elastos blockchain layer can be shared by multiple side chains. This greately lowers the mainchain pressure. When necessary, the sidechain can be duplicated to extend sidechain-level service capability through bifurcation mechanism, while the extension of this computing power can be infinite
Blockstack v Elastos?
Blockstack combines encrypted, distributed storage and blockchain ID to make sure all the data belongs to the owner. As for Elastos, it applies a similar method for digital assets storage where users could apply for an ID for their digital assets on the blockchain, which guarantees the ownership of those digital contents but a key differentiation with blockstack is that the ownership of these digital contents will also be transferable and tradable, thereby making these digital assets consumable and investable and of high value, thereby contributing to a smart economy of trading digital goods. Even though the digital assets are decrypted, they cannot escape elastos runtime operating environment which guarantees that it will never disclose or damage the ownership of the digital contents.
Blockstack saves encrypted data files in the cloud and hash stamps for these files are put on the blockchain as a proof mechanism but doing this is a trade-off between high credibility, low efficiency of blockchain and low credibility, high efficiency of traditional storage. Meanwhile, Elastos has its P2P network layer called Elastos Carrier that focuses on making the elastos blockchain cluster chain service integrated into the same network as the elastos runtime thereby unifying the services with DApps so both the data and the ID of digital assets can have high credibility along with high efficiency for blockchain storage.
For the tech savy?
Elastos VM: The VM runs on a host OS and has better integration with current mainstream OS such as Android and iOS. It ensures formation of a closed runtime environment enabling the separation from the host OS, ensuring safety of data and code. The ‘Remote Service Interface’ replaces the traditional TCP/IP programming model, providing safe and reliable network transactions. This means no more IP addresses and a discovery mechanism will be used instead to access dapps and websites on the elastos internet(where each item has its own UUID - Universal Unique Identifier).
Elastos Runtime: A software library that contains some of Elastos functionality. It provides the target OS applications with the needed Elastos functions, similar to the Alipay SDK serving other applications and making them capable of having payment functions. Elastos runtime can use trusted network communications and conduct safe and reliable data exchange and allows information exchange with the blockchain, confirming digital asset ownership and identity.
Elastos Browser: A specialized browser where the Elastos runtime is embedded. In this browser, web applications can run with partial Elastos functions. Using Elastos browser bridges the gap to provide JS programming...
