Honestly, you don't need to know even the tiniest technical bit in order to get involved with crypto. If you're in here for the money (which most of us do), you only need to know the basic who, what, when, where, why and how of bitcoin. Other than that would be your choice if you'd pursue learning them. Next is to think first before throwing some cash on a certain coin. I know it's easy to see crazy gains from other people but believe me, most of them only lures you in their trap to take your money. It's also vital to not blindly trust anyone on any 'investing tips' as most of them already have a great position in the market and, at times are just waiting for someone to dump their bags to.
