you are right, the 90% bitcoin already mined, so there are only 10% bitcoinin the world that can be mined, you need to know that the diff increasing. so 10% will be fully mined in a very long time, and if its already mined 100%, i think the price of bitcoin will increase, because the demand will be higher than the supply. am i right?
Actually you just completely repeat the OP whole content. Maybe you should read it before you make any post on any thread. Besides that, there's no guarantee that the price will increase after that since its only 10% iand it will took 100 years to mine that, So the price increased will happened gradually and not by an instant once the last Bitcoin mined. There will be a lots of roller coaster ride for the price so we can assure that price will gonna be up when that time comes.
