It's a good question who controls the bitcoin. I think a group of dev controls it. Because for bitcoin, there are some private keys (for checkpoint and alert) that if one has it, he will be able to propagate his own blocks into the network. I think a few people hold the private keys there.
There's actually a website that has the private keys of all the bitcoin addresses. Funny because even if you do have it all saved on a .txt file, if will take you a lot of power and time (even years) before you can find the private key of a specific wallet. There have been discussion about this in this forum. There are just too many bitcoin addresses available and I really mean way many for you to be able to control bitcoins or hack someone using the list of all private keys.I'm curious why people still believe in this nonsense
The site you refer to can't contain the private keys of all potentially possible bitcoin addresses by any chance since just to store them in some format would require all the Universe converted to storage devices and that would likely still not suffice. The guy who started that thread (I won't post a link so as not to promote it) is a shill who is deliberately spreading outright FUD. If the point is that the site can calculate all bitcoin addresses, I can just as well claim that the algorithm for calculating a Bitcoin key already contains all possible keys itself
