Currently, $DYDX has its own chain independent of the ETH network. The withdrawal fee on the dydx network is 0.3 to 0.5 dydx, while withdrawals on the ETH network range from 3 dydx to 5 dydx depending on whether the ETH network fees are high or low. Therefore, Binance's decision to stop supporting ETH network withdrawals and deposits for dydx is not bad for dydx at all. Anyone with their own chain should use their respective network like Sui, Sol, Apt... L1 will withdraw on their own network, and the fees will be much cheaper.
