At first glance, I was shocked to see 50000 BTC long contracts liquidated! How can the current market's fragility withstand such a blow. Take a closer look, it's okay, okay That was in 2018. Anyway, the current market is extremely boring, and we can only make a living by eating melons. If there's really no such thing, go and explore history and write a costume drama that everyone would be happy to watch. What did 50000 BTC mean at that time? I really looked up the relevant data with great interest: 1. In 2018, the highest peak for OKX was a BTC balance of 62755 coins; 2. In 2018, the US dollar value of BTC reserves on the OKX chain was 34.18 million US dollars, roughly equivalent to 8500 BTC at that time. These data are not enough to look at now, but they were already at the top level in the industry at that time. In this context, no exchange would allow such a situation with abnormal potential risks to occur, after all, this is not a matter of making money or losing money, it is a revolution that seeks to change the fate of the exchange. As the saying goes, one learns from a setback. With the development of the industry and after experiencing a series of unexpected risks, all exchanges have now raised the standards for "risk reserves" and "on chain reserves". For platforms, security, stability, service responsiveness, and the ability to maintain continuous liquidity in the face of drastic fluctuations are the core competitiveness that can win the trust of more users in the future.
