I thought that this is all about exchange where you can able to withdraw Bitcoin at a cheaper fee. Like others said exchanges with expensive withdrawal fees like on Binance its 0.0005BTC which is very expensive you can only get a cheaper withdrawal fee if you send it through another network but only other exchanges have different networks or receive them through Metamask that support other networks like BSC Bep20, TRC20 or other networks that offers cheap transaction fee.


Actually, you don't need to worry about the transaction fee today because it's totally 1sat/byte it's not sometimes but the fee is always 1sat/byte.

Also, take note if you want to pay cheaper always use Segwit addresses.
