Recently, watching those "sandwich + arbitrage" on the blockchain feels a lot like being cut in line when buying food on the street... You think you've found a bargain, but actually they're biting from both sides before and after you, and in the end, you even pay for the meal box. Honestly, now when I see phrases like "slip points for bigger deals," I get a bit cautious. Sure, opportunities exist, but more often than not, they're just someone else's source of transaction fees.

And lately, hardware wallets have been out of stock everywhere, phishing links are flying all over, and everyone's safety awareness has suddenly skyrocketed... I’ve also been forced to behave: set limit prices whenever possible, don’t randomly authorize, write budgets on paper, and if you lose money, consider it a lesson learned (but not too expensive). Anyway, when you encounter those moments where the price is suddenly pumped or dumped right at the moment of transaction, you'll first blame your slow hands or blame someone pushing you from behind...
