They are trying to chase profits wherever they are. They had an attempt to control the NFT and DEX market and it did not succeed, and I do not think that they will succeed in the Inscription Market. If Binance were to do something like Facebook, where they set their sights on successful companies and acquire them, they would have access to millions of dollars, but they follow successful projects and try to imitate them.
I believe that Binance has its reasons to build the best solutions for the BNB chain ecosystem. Binance wants to provide a full range of trading services to users, developing its own NFT and DEX trading platforms is necessary and very convenient thanks to the reputation of Binance CEX: they can reach hundreds of millions current users of Binance. It also affirms the Binance team's ability to develop Dapps.
However, to be honest, Binance's NFT and DEX services have not really taken off and gained many users. For example, I am a user of Binance CEX, I often prioritize experiencing and using Pancake Swap instead of Binance DEX, even though PancakeSwap is also a product supported by Binance Labs.
I hope that Binance Inscription marketplace will be successful and capture the Inscription trading market share. Let's wait for a report from Binance about what the Binance Inscription marketplace has achieved.
