Do you know if coinbase fee is cheaper?
I don't think coinbase is cheap, it take 1% to withdraw and 1,49%-3,99% for buy and sell. Maybe you refer to coinbase pro, because the fees is more cheap rather than coinbase [1]
While Binance, it take 0.0005 BTC to withdraw and 0,1% for buy and sell.
What coins do you have? because the answer on this question will answer depend on your holdings.
If you are just going to withdraw a specific coins/tokens, you don't have to worry about its network, you just need to have the address of the coins/tokens you are withdrawing on your external account, for example BTC to BTC address only.
Better to read the whole post than just the thread, he already mention the coin is Bitcoin.
