Started using OpenSea to see how it works. Hive has a good NFT platform called NFT Showroom(link containing my referral) but I decided to first try OpenSea since minting, listing and trading can be done with almost no fee if using Polygon chain. And there are even a piece which costs less than 1 cent so I can try different things to see how it works with little cost! There are some good pieces in NFT showroom which I am planning to purchase but I don't have enough Hive for now so I would first try and feel how the NFT market works through OpenSea and then come back to NFT Showroom to purchase some quality pieces.
