Eventually banks will embrace Blockchain and use it to their advantage (don't know about BTC specically tho). But blockchain will require a HUGE increase in efficiency before it becomes commonplace.
I agree with the statement. Banking will adapt blockchain into their banking services because In the future we don't need banks to secure our money because our assets will be right on our digital key files and or hardware wallets.
even the world is adapting fully into blockchain but certainly there are still more reasons why we need the banks especially on money loans so that we could get capital for our business and personal projects.
