i dont think BTC will replace banking in the future. Everyone knows that banking is belong to the Government and it can not be replace

that is an interesting question. Blockchain is growing really fast and more popular . That thing is possible

Bitcoin is a semi-anonymous currency, Bitcoin address owners are not explicitly defined but transactions are public.

Currently no one wants to sell BTC because of its low price, most of them will keep and wait when the price is stable.

I agree with you, Bitcoin may be the future exchange tool, is the foundation for future projects using Blockchain technology.

 Somebody think it is scam but to me bitcoin is not. To be honest, Bitcoin is not scam .
