In December 2018, when the market was in a panic, many big vs jumped out and shouted that bitcoin was going to zero, digital currency was the biggest ponzi scheme. I remember that in my community at that time, there was also a flood of pessimism, and a lot of people started to panic and started to waver. I wrote many articles and elaborated on different platforms, trying to prove through technology that the market was not as terrible as people thought.
