Dai is a stablecoin. It is an Ethereum ERC20 token that is pegged to $1 USD — every Dai is worth $1, and will always be worth $1, regardless of how much Dai is in existence. There is no centralized authority like Tether that backs its value, and no traditional bank that backs each Dai with a real US dollar. There is nothing that can be shut down, and no centralized authority that needs to be trusted. Dai lives entirely within the Ethereum blockchain using smart contracts. *Features of Dai: 1. Dai is always worth $1 USD each 2. It can be freely traded like any other ERC20 token 3. Anyone with an Ethereum wallet can own, accept, and transfer it 4. It can be exchanged without any middleman 5. No individual person or company has control over it 6. No government or authority can shut it down *How Dai Works? Dai is a masterpiece of game theory that carefully balances economic incentives in the pursuit of one goal — a token that is continuously approaching the value of $1 USD. When Dai is worth above $1, mechanisms work to decrease the price. When Dai is worth below $1, mechanisms work to increase the price. The rational actors that take part in these mechanisms do so because they earn money anytime Dai is not perfectly worth $1. This is why Dai is always floating slightly above or below $1 — it is an endless wave function bouncing infinitely close to $1, but never quite achieving it. The farther Dai goes from $1, the more incentive there is to fix it. This is the magic of Dai. *How is Dai Created? Dai is simply a loan against Ethereum. By using the MakerDAO dApp, advanced users can take loans out in Dai against their ETH holdings. First, ETH is turned into “wrapped ETH” (WETH), which is simply an ERC20 wrapping around ETH. This “tokenizes” ETH so it can be used like any other ERC20 token. Next, WETH is turned into “pooled ETH” (PETH), which means it joins a large pool of Ethereum that is the collateral for all Dai created. Once you have PETH, you can create a “collateralized debt position” (CDP), which locks up your PETH and allows you to draw Dai against your collateral, which is PETH. As you draw out Dai, the ratio of debt in the CDP increases. There is a debt limit that sets a maximum amount of Dai you can draw against your CDP. Once you have Dai, you can spend or trade it freely like any other ERC20 token. *There are several important reasons why you would create Dai, despite the hassle: 1. You need a loan, and have an asset (ETH) to use as collateral for your loan 2. You believe ETH is going up in value. You can use your CDP to buy ETH on margin — you lock up your ETH in a CDP, draw Dai against it, use the Dai to buy more ETH on an exchange, and then use that ETH to further increase the size of your CDP. This can be accomplished without any third-party or centralized authority allowing you to do so — margin trading can be accomplished entirely on the blockchain. 3. The demand for Dai has driven the price above $1 USD. When this occurs, you can create Dai then immediately sell it on an exchange for greater than $1 USD. This is essentially free money, and is one of the mechanisms the Maker system uses to keep Dai pegged to $1 USD. Dai being worth over $1 USD encourages more Dai to be created. These three reasons are enough to ensure that Dai is continually created.
Binance Coin is the cryptocurrency of the Binance platform. It is a trading platform exclusively for cryptocurrencies. The name 'Binance' is a combination of binary and finance. Thus, the startup name shows that only cryptocurrencies can be traded against each other. It is not possible to trade crypto currencies against Fiat. The platform achieved an enormous success within a very short time and is focused on worldwide market with Malta headquarters. The cryptocurrency currently has a daily trading volume of 1.5 billion - 2 billion US dollars and is still increasing. In total, there will only be 200 million BNBs. Binance uses the ERC20 token standard from Ethereum and has distributed it as follow: 50% sold on ICO, 40% to the team and 10% to Angel investors. The coin can be used to pay fees on Binance. These include trading fees, transaction fees, listing fees and others. Binance gives you a huge discount when fees are paid in BNB. The schedule of BNB fees discount is as follow: In the first year, 50% discount on all fees, second year 25% discount, third year 12.5% discount, fourth year 6.75 % discount, and from the fifth year onwards there is no discount. This structure is used to incentivize users to buy BNB and do trades within Binance. Binance announced in a buyback plan that it would buy back up to 100 million BNB in Q1 2018. The coins are then burned. This means that they are devaluated to increase the value of the remaining coins. This benefits investors. In the future, the cryptocurrency will remain an asset on the trading platform and will be used as gas. Other tokens that are issued by exchanges include Bibox Token, OKB, Huobi Token, and more.
