Yeah of course you should believe in Bitcoin because it can allow you to make some money and that can be really nice. I am believing in Bitcoin and will continue to do so if I can make money with it.
Yes we all believe in bitcoin and that is the reason we are investing our time and efforts behind it so that we can manage to have more number of coins for future which can give us better benefits.
I am very interested to learn well enough to work and earn bitcoin, only confidence I have not yet acquired the full. I advise not to buy bitcoin until I learn.
