Some media shows that bitcoin can be the next weapon to control the world economy. i think it is true and it will be seen soon.
Yes, I agree with you what you said because bitcoin can control the world economy and especially now that has been powerful of bitcoin today.
I don't think so. Yes, BTC can be important some day in future, if it reach some high prices, and if it is adopted as a primary online currency. But I still don't see the way that world can function without paper money, or particularly without banks.
