You can fund your CEX.IO BROKER account in these ways:
Transfer BTC from your CEX.IO account
Deposits from CEX.IO accounts are instant and free.
To transfer funds from your CEX.IO wallet, go to the main menu in the upper right corner of your CEX.IO BROKER account, select Deposits and Withdrawals, choose the account you want to fund, enter the amount to send, and press Deposit.
If you don’t have BTC to fund your account, you can easily buy some for fiat money on CEX.IO and then transfer it to your CEX.IO BROKER account.
- Deposit BTC directly from an external wallet
To fund your CEX.IO BROKER account directly, go to Account Management, select the account you want to fund, and press Deposit.
Keep in mind that in this case, blockchain fees apply to transfer BTC from your external wallet to your CEX.IO BROKER wallet.
