I think it is very likely that this market will disappear. When big financial investors play the game, profits will be generated when new investors enter the market. However, I find that the more confidence in this market is reduced. It is too unstable, prices are rising so fast in a short time and so dropping so fast. The financial sharks control the price of the market, and retail investors are constantly losing money. I believe that when the confidence in the market is gone, the market will collapse
Bitcoin Market will never collapse except if people will give a reason to do it. Yes, their is so much wrong doing of human that can have a big effect in the cryptoworld such as Scamming other people, laundering and fraud and using bitcoin in illegal activities. I think this is the reason why bitcoin market could collapse. However, we could prevent it to happen, but we can not dictate people to do it right because there is still a greedy person when it comes to money.
