NFT's are unique pictures stored on a Blockchain and it gave a big hype around NFT's so far.

But please do your own research what is a NFT. It is just a picture stored on a blockchain and every day new pictures are launched.
It is not really scarce when always new collections are launched.

Over time, only very few people will buy such pictures and NFT's will get very hard to sell because nobody wants to buy old NFT's in a few years. Why should someone still pay high prices for such pictures?
I really don't know if NFT is a good investment and buying NFT's right now looks very high risk.

It might be better to get out ASAP and sell all NFT's.
It is much better buy coins because coins will have a high demand later. Coins will always be required in Blockchain interactions, especially big and scarce coins. Only scarce coins like Bitcoin are a good store of value.

Better buy coins, not NFT.
