I also believe in bitcoin and I do not doubt its growth, I can say that bitcoin is more and more scaled in the world and this attracts new investments, and when the moment comes when the last bitcoin is mined, the offer will be limited and the demand will increase from which the price will go up higher
I believe that the future is not in bitcoin but it is in people whom is moving to make his/her future. But that bright future will be created and achieved with the help of bitcoin. That is the reason why bitcoin can be equal to someone's future.
