As far as books, I like "The Age of Cryptocurrency". Coinbase has some short lessons on their site. There are also TED talks. Here is one: https://www.ted.com/talks/don_tapscott_how_the_blockchain_is_changing_money_and_business?language=en

If you're a newbie, I'd avoid the meme coins and the margin trading for now and stick to dollar cost averaging into a few quality coins to start with. As you learn more and get more comfortable, you can take more risks.

there are also some youtube channels that are fun to watch but be careful not to take too seriously, a lot of them are not actually giving good advice, so... take with a grain of salt!
