They are only good at business, I see little creativity in BSC projects because they are mostly projects that are copied from each other and Ethereum.
BSC is just a high-speed, low-cost version of Ethereum. I do like the advantage of BSC though, as they drew developers from their rival Ethereum.
The success of BSC because they already have background as a big exchange. So, they can put many advantage to the platform, example using BNB as a discount tokens, hyping developers to build tokens on BSC so its easier to list on Binance, and many else. Also with the power of CZ to influence crypto user, their marketing will be very smooth to gains user.
