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
For a true cryptocurrency, specifically Bitcoin believer, it would be easy to say that Bitcoin really is the future. However, to justify such claim, that's where the difficulties come in. Many people are still in doubt about the legitimacy and the capacity of the cryptocurrency market to actually make it big and give profitable returns. That's one reason why many don't want to embrace the cryptocurrency market and truly immerse themselves in the benefits it can bring. For a supporter though, like many in this forum, there are more reasons to believe that Bitcoin is really the future, especially seeing the many people that have gained so much because of it.
