I have happened to find it very interesting that bitcoin will cap out sooner or later. I believe that it will be worth much more when it hits it but a few years down the ride quite possibly it may be worth nothing. Anyone got any predicts and a good reason why?
Honestly, it doesn't matter if it reaches 21 million or it is 18-19 million, the upcoming coins are mined both really slowly and also doesn't really make a huge difference in the market. They are good for miners but that is about it, no one else takes any advantage out of it. It is not like we are at 700k bitcoin right now and 20+ million to mined. There is only couple million left and the important question is what will happen when it is getting closer to the 21th million coin.
The reality it will never be mined and whenever it gets close there will be a halving that will fix that. If the miners start to not make enough from mining the coin itself they will need to make money from transaction fees and unless we figure out a way that will make them a decent chunk of money to cover the difference than they may stop doing that work and suddenly leave us with a much slower blockchain.
