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.
Because of a lot of opportunities bitcoin can give us, of course we have to believe with it because those people who don't believe in bitcoins are the ones who don't know it yet.
And that is already an advantage to all of us that we are able to have a chance of earning with a crypto currency and for sure that is going to keep on working if keep on believing it.
