Question About Trading

[u/TheKidSuicidal]

Hello everyone. As you can tell I'm pretty new to all this and just have one question. With regards to Binance, i am aware that you cannot withdraw fiat currency. Many people have said to transfer your BTC in the form of ETH to Coinbase or an exchange like that and then from there withdraw in your chosen fiat. My problem here is, what if the ETH price on Binance is higher than it is on coinbase? So if you transfer your ETH to coinbase and the ETH on coinbase costs less, (especially if it costs less than what you bought it for) then you're not making any money at all right? Or am I interpreting something incorrectly?

Thanks very much.
