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 am pretty sure that bitcoin will have serious competition by some other crypto currencies in 5 five years and maybe will be not that important anymore as a payment method like it is today.
