Hi Kristian,

Yeah at the moment I believe the best way is to reverse the process and withdraw it via your bank account on Coinbase (or Paypal for a fee, but I advise against that). That being said, on the way back, send it directly to your Coinbase wallet. You don’t get any benefit sending funds to GDAX, only withdrawing. If you do send it to GDAX, it won’t cost you anything extra, and I believe you can still withdraw from GDAX to a bank.

Binance does not directly link with normal currencies (fiat) like USD. That way, they can avoid a lot of red tape on their end, but it comes at the cost of convenience.

Take all of this with a grain of salt, as I have yet to withdraw any funds to USD.
