At any time, unless you haven’t paid the transactions fees and they are over $1, you can withdraw any crypto you have in any network.
To do that, you just need to go to your dashboard in the home page and press on the withdraw button. You will be redirected to a screen where you can choose which token you want to withdraw, which amount, which network you want to withdraw to and the address to withdraw to.
Since the transaction is on the blockchain, you will have to pay the network fees of that blockchain. That amount will be displayed in the withdraw page.
