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 believe that block chain will improve a lot more because the technology is advancing so transactions will become more faster in the future and slow transferring of coins will be a lot more faster and maybe lower fees as well.
Yes with the passage of time we can expect that the blockchain technlongy will continue increasing, because the new emerging blockchain technology is the need of the day and, people are now taking interest in online currency and that is the reason that we can see a lot of crypto currency already created and so many other currencies are still creating.
