How to learn to use electronic currencies?

Question

Cryptocurrency

I know superficially information about electronic currencies (bitcoin, etherium, usdt, digital yuan, ruble, etc.). Never really delved into it. It became interesting as a user. Advise useful literature, otherwise there is some kind of mess in my head on this topic. For example, there are different exchanges, you can throw funds there in some way, buy e-mail. currency, and then, bang, hello guys, sanctions have arrived; the owner of the stock exchange fled with billions, etc. I'm more interested in a comprehensive plan of action to achieve "power user" status.
