I am also wondering if it is possible to buy all or a very high amount of bitcoins by a bank or something like this just to regulate it
Discussion
I'm sure there might be forces that would like to centralise bitcoin in order to take power and money. And there's probably some people who own alot but I don't think that gives them more power to regulate. But I'm not the right person to ask. I know very little.
Owning a lot of Bitcoin gives you no more power over it than owning a little. Only running a node gives a SAY in running Bitcoin and only very little. Could they run a lot of nodes? Sure, but still that's not where I see they're headed at and I don't think they really understand that is where the power lies. But everybody should run a node. Makes it harder for institutions to control Bitcoin.
