I believe there would be a next version of nft which deeply integrated to metaverse such as land, items so that ppl could use for ads
for now, it is trash and over value.
Land and items already exist . But selling Nfts as Ad locations where you can customize ads is actually a very good idea. PIctures on those ads however should go trough some filters/people to prevent any illegal material but the idea is very good. Games are already selling ad spaces and you can name space stations etc for money, so it would make sense that these as spaces would easily be transferable in nft markets.
Advertisement is one of the things I think of in generating money from metaverse. I believe that some metaverses is doing it right now. This can be big and prices could ramp up higher depending on how people visit and engage to a certain metaverse. Filters should really be a thing in renting a space ad, There would be people who would most likely put their unlawful advertisement where it shouldn't be. It could catch the authority attention and make a move about it which is certainly negative for crypto and the whole metaverse.
