I heard the news, that banks are afraid of bitcoin and can replace banks, because the excess of bitcoin is much compared to local banks
I guess it is, for them. I mean I think they are really afraid of bitcoin taking over and dump fiat money because they can't profit from bitcoin actually they can but it's a lot lesser profit than fiat money and risky knowing that bitcoin's price isn't stable. Besides we don't need bank to stock our bitcoin we use blockchain wallet instead. And they are really afraid of that because bitcoin is used by mostly of the people now and they only have less chance to earn plenty.
