I just saw someone post a screenshot of sandwich arbitrage. Others thought it was on-chain picking up money, but in reality, you’re the one paying the fees for an MEV bot. The big players are laughing at you from the shadows. Lately, hardware wallets have been out of stock to an absurd degree—my friend wants to buy a cold wallet but can’t get one. And at the same time, phishing links are being pushed heavily; in the group, every day someone posts fake news like “Help me verify my wallet.” Anyway, I think arbitrage is like security: don’t just stare at that little profit—first check whether you’re the one fronting fees for someone else.
