Cold knowledge: $2100 USD, unable to dominate Bitcoin in 2018, does have an impact on the market, but it is too far from the word 'dog market'. A colder piece of knowledge: In 2013, Zhu Rong raised 10000 bitcoins and created the first futures platform in the cryptocurrency industry, 796. In 2014, OK also developed a similar product, which was called OKCoin at the time. In 2018, you said that the exchange was in a primitive era, not just a buddy, not someone who played late and represented you when you started playing. In 2018, these exchanges experienced various events. Not to mention futures liquidation, during the delivery of contracts from 2014 to 2016, it was common to intentionally liquidate positions and manipulate the platform, eat corpses, place orders in corpses and pretend to be big corpses, and eat corpses to become corpses. In 2014, Huobi also broke out in a series of spot positions because of the online Lite Coin. This word sounds incredible. How can spot positions also break out? Because there was financing and coin raising at that time. I say this, the technical accumulation of these exchanges in contracts in 2018 is basically no different from now. I still say this, there will be such incidents with Brother 5w in the future. The biggest problem is that the exchange operates on its own, only making profits and not losing. When it feels like you have a steady stream of money, it restricts you from opening positions, which is nothing more than using rules to deceive those who comply with the rules and changing the rules to manipulate and exploit the rules. Yes, trading all proprietary positions, every one. Not only do we have self operated stocks, but we also had C2C self operated stocks before.
