Just paid my tuition again: one exchange attempt failed, the gas got burned first, and I didn’t get the coins… I was still sitting there cursing, “This chain is so expensive,” and my fingers still did the honest thing and hit confirm. Looking back, it’s really my own overconfidence. I set slippage low, the pool depth was just average, and of course I picked the moment when the market suddenly popped and chased the order—by the time I confirmed those few seconds, the price had already run off, and it directly reverted. Hilarious.

From now on, for cases like this, do it in two transactions—don’t time it to the moment everyone is rushing to buy. Taking a half-second delay is actually more stable. Also, I saw that large on-chain transfers and exchanges’ hot/cold wallets were being interpreted as “smart money coming,” but honestly, I’m more afraid now of turning into “the smart money’s transaction fee.” Tired, but still here. That’s it for now.
