I have been thinking about making money in cryptocurrency, but I'm hesitant to try because I don't want to get scammed i.e. didn't get any rewards for the effort I spent. I'm really curious with the current hype in 2024 and how much you've make from it? I know that scam is inevitable in altcoins, so I might be looking to earn with less risk.
What I know the current hypes in 2024 are:
1. Testnet airdrop
2. Meme coins
What about NFT or ordinals? but I think it's really risky because it's non fungible and you can't make sure people will buy your token.
What about P2E games? I haven't hear it anymore.
Probably I missed other hypes or if you know the another way of making money, feel free to comment.

Only with real risk you are making real money, bigger the risk, bigger the potential gain. You either risk using your time for nothing or investing money for nothing. And yeah, you are right, illiquidity of NFTs is problematic, but i also have gained ton of good airdrops with nfts and i am assuming that holders of ordinals would get them some point as well.
Best testnet airdrops are going to be those that are not announced beforehand, and you just have to guess them, so you will be most likely losing money in fees and playing with dexes.
