The dump last 2017 made a huge difference on crypto world particularly crypto users. Many investors also dump their coins and panic sell. This was the reason of the bankruptcy you were talking about. The sad part is that, those people who are into it also lose faith investing. Lets understand that the market is just normal and you are not lost if you dont sell at a lower price.
But I would not say that there are many such people. Simply against the background of a general decline in the market, people began to invest more in the long-term perspective.
