A good reputable brokerage (a real brokerage). Lots of people seem to like Fidelity. A Vanguard account was set up for me over a decade ago and it's fine for purchasing, holding, and selling. Fidelity and Vanguard are both very popular, and for good reason.

Tasty is a good company that has great desktop software and educational resources for trading. You could go long GME shares, but also sell a put or buy a call if you're bullish but don't have as much capital as you'd like to invest. Maybe check out Tasty and the Tastytrade resources. Their educational resources really are great, and the software is better than anything else I've seen.

I didn't understand it like I do now, and there's still a ton I don't know.
