Opensea going to 0% royalties is the end of many bad business decisions. They tried to compete with Blur on trading and failed. Opensea had the chance to position itself as the "collector's marketplace". Thus present themselves as a real alternative to Blur's vision of Web3 which is focused on day trading. Full royalties. User-friendly interface. More social elements with focus on communities. NFTs as they used to be. They missed it and tried to become a second Blur, just with less liquidity and without a token. The question is, who will fill that gap in the future?
