>>5755592The Little Book of Common Sense Investing is a good starting point, even if you don't plan to stick with boomer-tier Index Funds.
I learned everything I know about Options and other types of stock market investing just from the internet. You'll want to learn and understand the greeks (Delta, Gamme, Theta, Vega), as well as specific strategies like a Covered Call, Poor Man's Covered Call, Strangles, etc before you try options. There's plenty of good sites that will come up to explain the concept of a strategy:

Crypto I also learned about through the internet, and I've made considerably better returns than from stocks already. Now I mostly stick to keeping the biggest percentage in Index Funds, then most of my Crypto is in Bitcoin and Ethereum since they're expected to be more stable (despite still having huge swings). Then I try to always allocate a smaller percentage to altcoins that can be high risk.
I also tried some shitcoin gambling for the hell of it, and while a couple trades were very profitable, most fail and wiped out those profits pretty easy.
Don't blindly invest in anything from a recommendation in /biz/, but it can be a great board to view to discover things to research separately. Lots of shills, scams, and idiots there just like any other finance board.
