We dont even know what is going to happen tomorrow, and you want us to tell you when bitcoin and digital currencies like bitcoin are going to take over all the system?
It is impossible, maybe not at this moment, but we all are going to see a huge advance about money and how does it works in a few months from now, or maybe in years.
But yes, the whole system is changing right now, and a lot of banks are now addapting themselves to bitcoin and all the other cryptocurrencies, because it is needed.
