did you check sorare.com, or NBA top-shot, they are both platforms for sport NFT's with strong growth last year, and Sorare platform has some amazing sales, like Unique Mbappe for 111+ ETH and similar
basically, Sorare is selling playing collectible cards, that can be used in their fantasy football competitions, with rewards in ETH and new cards two times a week (mid-week and weekend rounds)
NBA top shot is still in beta, but already selling top moments from NBA history and current season and lately had 25+k USD sale for one Legendary moment

there is a lot of upside potential for NFT's, but there is also a lot of useless NFT's that flooded the market, and probably will have no use in the future, but also some with value that will go up, but the market is already heated, and one should be careful with prices
