Now there are a lot of worthy projects, but if you choose only one instrument for investment, then it will definitely be an NFT project. After all, the future belongs to them. One of my favorites is Centaurify. I recommend to learn more about them.
Investment in NFT is good if you know how and where you need to do invest. But if you are new here, It's not suitable for you.
Instead of NFT, I suggest buying some low cap coins. Because it's a good way to make some money easily. I know there is a huge risk, So try to buy at least 5 coins. Before buying any coin research more and more. Buy only those coins that are listed at Top-rated exchanges like Kucoin. I use kucoin most of the time to buy Low cap coins. also, follow one rule in the crypto world: “Don’t invest any money you can’t afford to lose”
2021 was good for the IDO, Right now metaverse hype is ongoing.
So I suggest OP try to do your own research. It's very important in the crypto industry.
