Prerequisites
A verified Binance account (identity verified, not just email-only). USDT balance in your Binance Spot wallet. An open account at your chosen sportsbook with the deposit page ready.
On the sportsbook side
Open the deposit page. Select USDT. Select TRC20 network (cheapest). The sportsbook displays a wallet address starting with T. Copy this address. Also note any memo or tag if displayed (USDT-TRC20 does not require a memo; USDT-XRP or USDT-EOS sometimes do).
On the Binance side
In the top right menu, click Wallet then Withdraw. Select USDT. Paste the sportsbook's TRC20 address. Binance will sometimes display a warning if the address looks unusual; check the address character-for-character against what the sportsbook showed you. Select TRC20 network. Enter the amount you want to send (minimum is usually 10 USDT on TRC20). Binance shows a network fee of around 1 USDT; this is deducted from your amount, not added.
Confirming the send
Binance requires 2FA confirmation on withdrawals. You will see a verification prompt on your email or authenticator app. Approve it. Binance shows 'Processing' for about 1 minute, then 'Completed' with a TxID (transaction ID).
What happens next
The sportsbook typically shows your deposit within 1-3 minutes of the Binance confirmation, after 1 blockchain confirmation. If it takes more than 10 minutes, paste the TxID into any TRC20 explorer (tronscan.org) to check whether the transaction is pending or complete. If complete but not showing at the sportsbook, contact their support with the TxID.
Withdrawing back to Binance
The reverse flow works the same. Copy your Binance USDT-TRC20 deposit address, paste it as the withdrawal address in the sportsbook's cashier. Stake and Rainbet typically process under 5 minutes. 1xBet and Melbet take 30 minutes to 4 hours.
