I am swaying between two things at the moment. One there are in fact a few key players that control a vast majority of bitcoin and other cryptos. Those people are playing games and manipulating the markets and for those smaller fish that buy high and sell low they are losing out quickly. I can understand why they would want to exit and never come back.
Another side of it though says stock up and hold for the long run. Bitcoin will and should even itself out more as we progress further into the future. As more trading takes place and more FIAT currency pours into it.
I don't think it will ever be a world currency however. There is far to much risk to goverments.
So while I do believe $50,000 is possible for bitcoin and realistically easy I don't foresee it blowing up to a million and being a world currency because so few people how the majority of it.
