How has Crypto changed since 2020?

I got it to Crypto for a year or so back in 2019/2020 I made somw money with Shib and Eth.

I got really lucky and got into a popular NFT and sold it and made about 20k in a few weeks which was amazing.

I bought into Polkadot and Saitama when they were pretty new and then I got out after losing money on a couple other random crypto projects that were all the rage for about 15 minutes. I remember DOGE was gonna moon "Any day now $1 is just weeks away."

I want to get back in but I'm not sure where to start. NFTs, where I made the most money, and had the most fun seem all but dead. The one I sold for $19k is now for sale for like $20 which is just crazy.

So what are people doing in Crypto in 2025? Where should I start? Just bitcoin or are people still making money on meme coins? I found it a lot of fun trying to find the next big thing but they all seem to have to turned to nothing, Polkadot seemed the most promising and exciting project back then.

I looked at the new top performers and I dont recognize any of them lol.

Would love some suggestions.

Thanks!
