I don't think it can... Rather I would predict to be a co-existing situation with bitcoins and banks. For example, I am using HSBC while I am using ANX, no conflict with each other.
I share the same option with you in the short term. However, it is hard to say in a long-term perspective. The appearance of companies like ANX will certainly bring large pressure to the traditional bank industry. Let's wait and see how everything moves on.
can you explain more detail? I know that bitcoin and blockchain is a innovation idea. but it has touch the the core of government and bank(I still believe that money value come from military power). Why they still let these company growth?
