There are institutions that offer special classes for cryptocurrency subjects (though it still depends on your location). It's quite costly but worth it (I guess). Normally (based here in our country), The class will last for 16 sessions and part from that is the exposure to crypto trading.

Basically, almost all of the things you wanted to learn and to know about cryptos are available online. It's much cheaper to start with, though you must invest most of your time and effort and patience to relatively learn the things you wanted to learn.

Also, you could use this community, this site is a good source of information. Just spend time browsing and reading some posts here since most of your possible questions are already answered here.
