Most projects are migrating to binance blockchain because of the low gas fee, currently we all see that ethereum gas fee has been very high which is making it difficult to make transactions on ethereum chain, the gas fee which is always requested to send a coin on ethereum chain is becoming unbearable so people are migrating to binance blockchain which the gas fee is very low and fast, Also ethereum chain are always congested now which makes transactions always slow compare to binance smart chain that transactions are really fast and the gas fee is really low.
