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'm very optimistic about future of bitcoin.
2 years ago value of bitcoin was only $200 and last year around $700.
Today, even with this recent big drop, btc price is still much higher than last year.
So, regardless of the occasional higher falls, bitcoin prices are constantly increasing every year.
I expect that such trend will continue and that we will reach price of $10 000 very soon

Yes, bitcoin crossed $16000 now. But within next 5 years how much it grows ? It may breaks all records and create a history or ballon of bitcoin price will blast and drop to ground. Both chances are there. Time tell all.
