5 years from now is a pretty long time. a lots of things could happen in that period.
Furthermore it would be 2 years after the next halving, which is happening in summer 2020.
IF Bitcoin should still perform as it did since it's creation, $15000 is definitely possible.Probably more!
But there will be many more attempts to take over Bitcoin by bad actors, as we see going on now (NYA SegWit2x BTC1). And also huge and extreme FUD, just to separate the scared people and weak hands from their coins.
I do accept these things,five years is a very long time,but i am positive that the price would increase when it comes to the next halving because the last halving gave me a good profit,but how can anyone take over bitcoin ,because it is a decentralized platform and no one can take over ,i just want the best things to happen in bitcoin.
