I think in the future, banks will dissappear, Wallet online Blockchain or Coinbase will replace Banks, we can look forward to a world in the use of virtual currency and transaction technology of Blockchain, Banks not suitable for future
We are far away from a world where banks should be disappeared. Do you believe bankers will keep their fingers crossed and wait bitcoiners to take over the keys? In addition you mention the Coibbase. I believe that you told it as a joke. Do you know coinbase policy and complaints of its customers?
