Most people have this sort of dream where they can actually live off the internet in general, it all goes well until it does not, the forum and crypto in general are still sort of amateur, just like anything else in life, you may get lucky here and there , but as things develop only those who are actually experienced at something will end up making the majority of the money, so if you are just an average Joe, chances are you going to stick to your everyday's job till you retire.

I personally make more money mining and trading bitcoin than i make from my average IT related job, in fact if i quit my job today and invest all my time and effort in crypto, i could make 2-3 times more income, but then i'd be stupid, if crypto goes south i would be broke and will have to start all over after having lost all my clients and skills, things will be worse than ever.

TL;DR : unless you have a good amount of reserves, then living off the forum and crypto in general is too risky, there is nothing wrong with some extra income from signature campaign or trading goods and services, but don't go balls deep, just in case!
