I recommend depositing to Coinbase Pro and selling there. You'll save a boatload on fees. You can withdraw USD to your checking account from there, no need to transfer to Coinbase.
I started an account on Coinbase Pro but they won't yet raise my limits until I do some trading. I'm done trading I want and want to cash out most of my Crypto. So far that's all I have tried is Coinbase and Coinbase Pro. ON Coinbase I have 3rd level clearance. It looks like I will pay 3% on Coinbase. I don't mind paying some modest fee's to get larger amounts out quickly. I'm not a whale but I have a significant amount.
I'll probably do both until I get familiar with Coinbase Pro. I might even hook my accounts up to 2 banks in case I have trouble with one of them.
That makes sense.
I would max out your withdrawal limits on Coinbase Pro. They should automatically raise them after that. I've never used them to "trade" really, mainly just as a fiat offramp. My experience was that they automatically raised my limit to $50,000/day after I had made a few $1,000-$5,000 withdrawals.
