When you Buy Crypto in your Blockchain.com Wallet, the crypto will be held in your Trading Account. Your Trading Account balance is custodial, which means that Blockchain.com securely holds it for you.
You can keep your crypto in your Trading Account, sell your crypto from your Trading Account, Swap crypto in your Trading Account, or, if you wish to send the crypto externally, you can withdraw it to your Private Key Wallet balance.
To withdraw using our web wallet, click “Send” at the top of your wallet dashboard. Click on the “Currency” dropdown menu and choose the currency that was purchased. Next, click on the "From" dropdown menu and select your trading wallet. Click “Continue" to begin your withdrawal.
To withdraw from your Trading Account on mobile, navigate to your wallet’s dashboard and select the cryptocurrency that was purchased. The funds from your Blockchain.com Buy order will reflect under “Trading Account Balance.” Select “Send to My Wallet,” to have those funds sent to your Private Key Wallet for the currency selected.
If you haven’t made a wallet backup yet, you will be prompted to do so during your first Trading Account withdrawal. Your 12-word Secret Private Key Recovery Phrase will allow you to recover your funds if you ever lose access to your wallet. Learn more about backups here.
Once the withdrawal transaction has been processed, sent, and confirmed on the blockchain, the crypto should be available in your default wallet balance. From there, you can Swap it to another crypto, send it to the Exchange, or send it to any external address.
