I need some quality educational links to help me gain some further knowledge of crypto. I see quite a few posts about "do your own research" but I'm unsure where to start.

For reference I live in the US, use binance.us as my main exchange and use Exodus as a digital wallet (for now).

I admittedly got into crypto because of dogecoin, and while I understand it can be a gamble I'm also not using any money I can't spare right now.

I'm interested in staking and while I have heard my coworker talk about Eth Classic, I'm still hesitant to get in on that since he's not the most stable or the best information source on this.

I'm also a bit hesitant about investing more into any crypto right now since it seems a bit up in the air tax-wise and from what I've heard on a podcast they want to tax on buy/sell/trade at what seems to be high percentages on top of exchange fees for any of those transfers to and from coins and to and from fiat.

What general info websites do you use? How many coins do you recommend to have a "diverse" wallet for growth?
