Currently, there is a brainless arbitrage opportunity on Binance, with a single account limit of 5000 USD per day. Because of the quick redemption $USDC , the daily limit is 5000u.

The steps are as follows:
USDT purchase #RWUSD 1:1
RWUSD redemption becomes #USDC 1:1
USDC can be directly sold in the spot market, $USDC is now 1.0005

If an account has capital, clicking once a minute nets 2.5u, and even if there is no capital, you can still brush slowly for zero risk arbitrage.

⚠️ Note: The free limit per day is only 5000u, and pay attention to the USDC price. I just finished exchanging it before taking the screenshot, so the free limit is 0.
