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.
Once someone starts earning it he himself will start believing it, because before someone can earn it they think it is really not something achievable or it is something not for us or for the ones who are superior, but that is not true, bitcoin is for everyone and everyone can have it they work for it.
Im agree as I just continue my bitcoin journey the moment I received my first bitcoin earnings in an instant and no hassle at all. Much more when the first time I converted it in fiat and just says, "it's real!".
But you know in here, I already believed it at first although not that much. No way I will test it if I don't believe. If it fails me, then I will not continue. But since I got a positive result, I decided to continue.
