Hey there,I recently checked Lootex supports multi-chains and one of them is Polygon. Lootex has great MATIC NFT's and I believe NFT's going to be more popular in 2022. For those who enjoys to collect NFT's,im suggesting to check Lootex 
Nowadays, we are in the period of NFT season while we are facing altcoins season as well.
So, Lootex I think has a potentials in the future, based on what I checked on their platform, let see what's could
it be more happen in the future.
