Simple. Because EVRSea is cheap and easy.
It costs about $2 to create an NFT in EVRSea. This can cost up to $100 on competing networks. Moreover, EVR or NFT transfer fees are about $ 0.5. EVRSea's commission fees are also below many platforms.
EVRSea is very easy. Its centralized structure is just like exchanges. You do not need to download a EVRSea wallet and create an account to purchase and collect an NFT. Moreover, you do not need to protect the IPFS data of the NFT you purchased. It continues the IPFS service for every NFT sold on EVRSea. This protects you from very possible NFT losses.
