"Books"? Not that I'm familiar with.
BTC, Crypto & Blockchain info & tutorials are freely available ALL OVER the web.
The post you responded to mentioned $GBTC. This can be traded easily in stock & IRA accounts, and price tracks pretty closely to BTC.
There's generally a 'premium' to BTC but today it was ~5%, whereas throughout 2019 it averaged 25-35% premium. Soooo.... if you "like BTC", GBTC has been an easy way to participate.
Trading is a broad topic, but "trading these" can be thought of similar to trading ANYTHING.
The key rule: don't get MARRIED to any position - when a trade 'turns on you' it's time to kick it to the curb. You can always re-enter, but don't let ANY TRADE trade take too much money out your pocket.
