Only one man knows it, how Bitcoin will supersede the entire financial system with Blockchain technology ? and he is the real inventor of Bitcoin and Blockchain Technology Mr. Satoshi Nakamoto; A macro economist, digital scientist and social engineer.
Any body can answer to this question and get enlisted to get a bounty of BTC100 BTC.
Real answer, bitcoin won't do this and anyone that tries to tell you on this site is going to be biased when it comes to what they're saying. People don't understand that going from normal paper fiat currency to bitcoin would be insane, that would be a change and a half for people.
People wouldn't support such a drastic change, plus the money you're trying to give out as a bounty is a good laugh for me.
