Bitcoin 20 year from now? Hmm.. maybe it will stay alive if we all help to protect it from fraud and keep it on a good environment.. bitcoin is good for investment and also we can share our opinion about something! Its a good community. Maybe 20 years from now bitcoin can be one of currency out there.. who knows. That what am thinkin.
This is great to know that there are some people who thinks that bitcoin will be a real or fiat currency, and for sure if this thing happen it will be awesome to that great country that they accept the bitcoin not only by the people but also by the government itself.
