some countries banding bitcoin , some encureging , some people say its a replacement of visual currency , some saying its just a scam ...... whats the real future of bitcoin 
the future of bitcoin will remain one of the assets of the virtual currency. I still doubt the bitcoin can replace the fiat currency.
but, in an era, today is the era of digital technology. and almost everyone uses the internet as a tool of knowledge, transactions etc. this is why I believe bitcoin has a great chance until 50years ahead.
