slowly but surely bitcoin will kill the world of conventional banks.
inevitably conventional banks will use the blockchain system in their banking system because conventional bank customer data is still quite vulnerable to hacking.
I don't think that will happen, because the role of the bank is certainly still very much needed, although bitcoin has a good future and has been trusted by many people as a valuable form of investment, but in the future bitcoin will be an alternative tool that can facilitate everyone because along time will certainly be more and more people like the concept of this technology
