"Community" is a word that is closely associated with cryptocurrency projects, including bitcoin . Relatively recently, two exchanges appeared in the segment of the crypto currency, which decided to adopt a model, in the center of which the interests of this community are put. Contrary to generally accepted principles, these exchanges appeal to their users for advice on adding new crypto-currencies, encourage their participation in trading activity and demonstrate their willingness to share a part of their income with them. To this day, this model demonstrates its effectiveness. "Unicorns" - start-ups, whose value exceeds $ 1 billion, are almost as rare as mythical creatures, in honor of which they are named. The category of "unicorns" include, for example, Uber, Airbnb and Xiaomi. In 2017, another "unicorn" was born, which was hardly heard by the inhabitants outside the segment of the crypto-currency. It's about the Binance exchange, which was recently christened "the fastest and most profitable unicorn in history." 143 days it took Binance in order to pave the way to the top of the list of the largest exchanges, where it reliably and settled. In the last 24 hours , $ 5.5 billion has passed through this trading platform. However, this number does not give a complete idea. Binance, like Kucoin, has achieved success largely due to the fact that it prefers to listen to traders, rather than dictate their terms to them. Traditional models used by such well-known sites as Bitfinex, Bittrex, or Poloniex, which add cryptocurrency at their own discretion, are gradually disappearing into the past. Of course, they have reasons not to disclose their plans for listing in advance, but, as practice shows, sometimes a community council is simply necessary. Until the summer of 2017, Bittrex remained the chosen stock exchange among traders interested in altcoins. Over time, Bittrex simply refused to expand the list of digital currencies available for trading, and since its appearance Bitcoin Gold has included only Enigma and Unicoin Gold. It should be noted that Binance very timely came to the market, even as Bittrex announced a moratorium on the addition of new coins. Every month, the Binance community chooses from the range of proposed cryptocurrency that will eventually be included in the listing of the exchange. Instead of isolating themselves from their users, the new generation of exchanges demonstrates their readiness to listen to them. The inability to reach the support service and the lack of response to the needs of the community - these are perhaps the two most common motives that can be traced in discussions related to the majority of the exchange of crypto-currencies that took place on the market a few years ago. In contrast, Binance and Kucoin tend to encourage their users, including giving them discounts and even sharing income. During the time of general tokenization, the issue of its own tokens by stock exchanges remained a matter of time. Binance and Kucoin were able to find a successful application of such tokens in their business models. Thus, the Binance Exchange Token traded under the ticker BNB has grown by 8,000% since 2017 and at the time of publication, it costs about $ 9. Many tokens entering the market after the ICO follow the following path: Etherdelta > Kucoin> Binance; each new exchange adds liquidity and often helps the prices to rise even higher. At the same time, against the backdrop of startups like Cardano, which do not even have the least viable products and at the same time reach a capitalization of several billion dollars, Binance and Kucoin stand out prominently: their assessment is based on today's achievements, not on illusory promises. CEO Binance Zhao Changpeng showed that he is not afraid to compete with such giants as Coinbase, and is ready to present a worthy alternative. Binance has already started burning its own tokens: the whole exchange plans to destroy 100 million BNB, thus seeking to increase the cost of tokens remaining on the market. In addition, in the future, Finance intends to expand the functionality of its trading platform by moving to a decentralized hybrid model and implementing support for margin trading. A similar hybrid model is adhered to by the Bitfinex Exchange, which recently opened the Ethfinex division, thereby demonstrating that in the field of cryptocurrency, the very different trading platforms have the right to exist.
