Don't you feel like once the bitcoin price goes up, the main holders will be the banks and large financial institutions?
I don't think so. Banks will definitely not play such risky games. They have their reliable traditional ways of making money. And without the slightest risk or with minimal risk. I know bankers. Without almost one hundred percent guarantee that the money invested by them will return with a profit, they will not invest. These are all unsupported fantasies.
And I think it may well be true. What are the risks for the bank? If something goes wrong, the bank can declare itself bankrupt at any time and - no problems. At least, such cases have already been.
