If you are uncertain and has doubt don't invest yet. Try to dig into more information and check if NFT investment is for you. Not because you have seen many people getting rich because they invest in NFT, then think that they are not you. Your situation is different from theirs. They probably got in before the NFT is overly hyped and sold their holdings when the price is on top. Now the hype of NFT is almost gone, you can probably buy some in low prices but the question is who will buy your holdings. So better do your research intensively.
A quote from two of the articles I read about NFT
The Future of NFT Investment
NFTs are an exciting creation, and they’re garnering more and more attention as their use cases multiply. The headline-grabbing price tags attached to some NFTs are fueling the fire. However, prudent investors should tread very lightly when thinking about buying these assets because NFTs are highly illiquid and volatile.
Buying them with the hope of achieving triple- or quadruple-digit price returns is not advisable. The real value of NFTs lies in their potential to transform the way markets function and enhance the way we manage and control sensitive information. Here, the sky is the limit.
Nevertheless, if you want to participate in the blockchain movement and see NFT ownership as your way to do it, go for it. However, please do so responsibly. Don’t put a lot of money into NFTs and always strive to establish low-cost positions. Otherwise, you could find yourself in a painful spot — financially and emotionally.
The Bottom Line
The bottom line is that NFTs have pros and cons, but it's probably a bad idea to invest in any asset just because it's tokenized. The fundamentals of investing still apply, regardless of whether an asset's ownership is indicated by a blockchain. Your best move as an investor is to identify quality assets that you'd most like to own, and then do what it takes to acquire them.
