There is still a fake here. You are thinking about interest, while others are thinking about your principal.

A few days ago, I joined a Telegram group for staking ETH to receive BNB. You have to transfer ETH to a specified wallet address, and then BNB is automatically returned after 30 minutes. It claims to be an official Binance BNB mining pool for smart arbitrage, but I'm not sure if it's a scam.
