Sharing and correcting some common mistakes:

1. Binance has low trading fees, but high withdrawal fees; Okex is the opposite. The trading fees for stablecoins can be as high as 0.1%, and the displayed fees can be misleading.

2. The so-called Aave stablecoin lending returns of over 50% are short-term; on Avax, Arbitrum, and Base, stablecoin returns are around 15%.

3. Additionally, Binance's BFUSD returns are quite good, and Okex's USDT returns have been decent in recent days, but it's unclear if they will be sustainable.
