I'm getting a bit annoyed watching the mempool today: during congestion, your transaction is basically "queuing + being front-run." First broadcast out, nodes first put it into the pool, miners/validators pick and pack, whoever offers higher tips, whose order is more profitable, gets processed first... Honestly, you think once you click confirm it's over, but really, it's just throwing your order into the cafeteria window, and calling your number doesn't guarantee you'll get served.

What's even funnier is that in the group, people are sharing about stablecoin regulation/reserve audits, and at the same time shouting "it's about to de-peg, run!" When emotions run high, they wildly click on transactions, but when the chain gets congested, the transaction price and your expected price gap wide, and in the end, you're cursing the wallet/exchange/the whole world.

My current simple way to avoid impulsive orders is: when I see congestion, I first close the trading interface, check the pending transaction count and fee range, set a "don't send if fee exceeds this" deadline, and if I really want to trade, wait five minutes before coming back—if after five minutes I still want to trade, then it's me, otherwise it's just emotional mouse-clicking. That's it for now.
