This is a list of Binance withdrawal fees.
https://www.binance.com/en/fee/cryptoFeeIf the alts you want to withdraw have several alternative networks (and are Ledger supported) such as BEP20 tokens, you just need to find the cheapest one. But, it is highly recommended to use alts native network, as not all exchanges support certain networks (unless you only use Binance).
