I would like to see what will happen in a few years, and maybe even dozens of years Personally, I'm sure that the future is behind the crypto currency.

With patiently we know how potential the Bitcoin future going to be, we have seen many downfalls from 2010. Last year is the best year for the Bitcoin because the price of Bitcoin reached to ATH in the market and makes many companies and governments shocked by seeing the price.
No, it is not patience it is use of mind as using by Germany after accepting the Bitcoin and few other crypto coins they are making it a part of their lives in many ways in which it can help them out as we know that is friction-less so it helps in their banking system as well. They are using it as payment mode everywhere and even banks are using the Bitcoin to pay loans to others.
but the point is that bitcoin continues to grow and develop, the development of bitcoin makes many parties accept and adopt bitcoin right? as you said many banks also started accepting bitcoin? this is a good signal for the future of bitcoin, that bitcoin might take an important role in the world economic system..
