The third time chasing a "seemingly profitable" arbitrage opportunity on the blockchain, only to realize I was more like paying others transaction fees...

A sandwich, to put it simply, is when you think you're arbitraging, but they treat you as a liquidity withdrawal machine.
Now I basically avoid those sudden volume spike trades, preferring to place limit orders and wait patiently.
Missing out is just good practice for mental resilience, and looking back at the charts makes me quite clear-headed.

Recently, hardware wallets are out of stock again, phishing links are everywhere, and there are always people in the group rushing to click on unknown airdrops.
I sweat for them.
Anyway, I now prefer to use limit orders instead of market orders whenever possible, and do as little as possible to avoid turning "opportunities" into someone else's wallet wind.
That's all for now.
