There are so many different NFT collections. The price of NFT continue to raise. So the big demand appears in NFT. That is why a lot of NFT collections appear and investors have a big choice of what NFT to buy and how to choose the best NFT for investing.
Not all NFTs can be collectible and most of today's NFTs also don't provide sufficient returns for every investor and collector at this time, so why go after all NFTs when just one or two can be enough to reap the benefits.
