Thanks for sharing such valuable information! Just a quick off-topic question: My OKX wallet holds some USDT, and I have the seed phrase. (alarm fetch churn bridge exercise tape speak race clerk couch crater letter). What's the best way to send them to Binance?

Steps to Send USDT from OKX to Binance:
==================================
Login to OKX:
First, log into your OKX account (either via the mobile app or desktop).
Obtain the Binance USDT Deposit Address:
Go to your Binance account.
Navigate to "Wallet" > "Fiat and Spot".
Search for USDT in your wallet.
Click on Deposit, then select USDT.
Choose the appropriate network (usually ERC20 or TRC20 for USDT).
Copy the deposit address (you will need this to send USDT from OKX).
Initiate the Transfer from OKX:
Go to your OKX wallet.
Click on "Assets" > "Withdraw".
Select USDT as the asset you want to withdraw.
Paste the Binance deposit address that you copied earlier.
Select the same network (ERC20 or TRC20) that you selected on Binance. Be cautious about which network you choose, as USDT on different networks (ERC20, TRC20, etc.) are not interchangeable and could result in lost funds.
Enter the Amount:
Enter the amount of USDT you want to transfer.
Confirm and Complete the Withdrawal:
Review the details carefully (address, network, amount).
Confirm the transaction and follow any additional verification steps, like email confirmation or 2FA, to complete the withdrawal.
Wait for the Transfer to Complete:
Once the transaction is initiated, you will need to wait for the blockchain network to process the transfer. The time taken can vary depending on the network (TRC20 tends to be faster and cheaper than ERC20).
Check Binance for Deposit:
Once the transaction is complete, check your Binance wallet under "Fiat and Spot" > "USDT" to ensure that the funds have arrived.
