A crypto transfer on Gemini is the movement of a crypto to an external wallet or another exchange via blockchain transaction.
In order to move any crypto from one place to another, you would need a “destination address” which indicates where you would like to send your crypto.
Once you have the destination address, navigate to the appropriate withdrawal tab on the transfer page, select the crypto, paste the destination address, and enter the quantity of the crypto you would like to transfer. As always, any transaction (including crypto transfers) can be confirmed in your transaction history.
