bitcoin is five years time in my opinion there will be a lot of hard forks from the original bitcoin blockchain and the value of bitcoin would increase by 300 percent today's price. if transaction's speed and price remains the same, bitcoin's not improving and maybe the price wont grow that much
I have faith that bitcoin will be a mainstream currency in future. I hope people get educated about bitcoin so more people will accept bitcoin. In 5 year maybe all bitcoin get mined, I hope bitcoin price hit around 100K.
