I don't think that all cryptocurrency players have gone bankrupt, there are some people and I think that includes a lot of money for players to benefit from the existence of this cryptocurrency, only those who do not know how to trade properly and properly will go bankrupt.
Bankruptcies in financial investment are not uncommon, so if many investors fail to participate in cryptocurrency, they are not too surprised. Many people have become successful and wealthy but many have gone bankrupt due to lack of knowledge when investing in cryptocurrency.
