Many metaverses actively use NFT and continue to develop and interact with each other. For example, a next-gen gaming NFT utility initiative named Shuna Inuverse (SHUNAV2) bypasses that process by making partnerships with the already existing and future appearing tokens to share their metaverses.

The price of NFT depends on demand in them. Now there is a big demand in NFT and their price continues to grow.
Hope in 2022 NFT will continue to develop and the demand in them will increase.
People will continue to buy NFT if they will see that the price of NFT will continue to rise.
People buy those investments that are profitable and if they see the profit they buy the asset.
