I just want to put it out there that I love Btc and the rest of the crypto space and that it definitely is the future of how we humans are going to organize ourselves and the web, but I have one question:
If the only way to destroy/ hack/ manipulate Bitcoin is to own majority of the computers that actually run the Bitcoin algorithm what will stop a super power like USA or China to just acquire many computers and ultimately hijack BITCOIN?? See example below:
Currently there are approx 3 800 000 computers running the bitcoin algorithm. If someone acquires 4 mil computers then they will have control over bitcoin?
I apologize for imaging the worst, but these sort of questions need to be asked so all can understand better.
