I remember that on 1st January 2017 , the price of bitcoin is about $1000, but now we can see the price is already over $7000. To be honest, that is why some people said this is bubble since the unbelievable rising of bitcoin. However, let us look back upon the history, we can tell that Email subvert the postal industry, Amazon subvert the retail industry. Furthermore, Will bitcoin subvert the traditional banking?

Above is just my personal idea.If you like or not, I wish everyone here have a nice day.
