Well the new best things are DeFi, GameFi projects. they are on the rise now. You really need to do research before you buy anything, even if you do listen to people online, witch are 90% hard shill ads.
If you want my personal opinion, i recently invested in ENGN a gamefi project, they released a gameplay trailer a few weeks ago if you want to check it out, and Lunabets a decentralized sports book dApp that should launch March 22. 2022. it looks to be cool and promising, I got some money there but I'm waiting to see the launch and how will the developers handle it before I invest any more.
