Bitcoin has definitely fallen very much. But I think that this is deep, albeit long, but a correction before the next take-off to a price of 50,000 dollars. And by the way, I also do not believe that Bitcoin will ever collapse, in the sense of completely depreciate.
Bitcoin is not decentralized enough. A lot of coins are in the same hands. Therefore, we observe such ups and downs. This is all a consequence of the fact that a coin is easily manipulated. But the fact that Bitcoin and other coins can ever collapse, I do not believe.
