if you Look at Bitcoin closely as a decentralized currency that will overthrow the traditional financial system and take total control of the economy
There's a difference between
disrupting traditional finance and
overthrowing it. If anything, Bitcoin will force traditional finance to adapt and improve. It's probably fair to say that society has a bit of an addiction to debt which it isn't getting cured from any time soon, so Bitcoin will never completely take over. I certainly don't see any marxism here.
