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 positive that the value of All Altcoins, specially Bitcoin will increase to 3 time or even 5 times than today. It is just like from the start of Bitcoin is cost less but right now it is now in high value. Surely, 5 years from now, it will also have the same effect and it will definitely increase.
