I’m not a professional developer but I think I know little about bitcoin atleast I can boldly say I know the basic functionality and it’s essentials which include, buying and selling and also holding and all of these doesn’t require you to be a professional developer of bitcoin.
With this singular thought in your head, it will be very difficult for you to want to accept bitcoin and its functionalities and I will first advice you to picture bitcoin as a form of currency but the major difference should be that bitcoin is used digitally while the other is physically through fiat or barter.

Bro, Rome wasn’t built in a day and as such you don’t expect to get to know all the basics of bitcoin in a day, just as driving perfectly requires several experiences and practices, same as bitcoin and cryptocurrency at large.
