I did thought that everyone would appreciate if these big firms entered crypto just as they have done now? I used to read topics in these boards in the past and one of people's wish was to see Bitcoin get massively adopted by individuals, banks, big firms and government coz that would help the price grow. The price has grown now due to their involvement but they can chose to sell or manipulate the market and they own majority share of Bitcoin coins.
They can manipulate the market, they have the bigger amount now which really is scary if you think about it. The only solution is to hodl to your bitcoin even if the price is still increasing because they might be planning on monopolizing the prices by selling them when there is nothing available at the exchanges.
