Mempool queuing, to put it simply, is like you’re throwing your transaction into a “waiting room,” and miners/packagers only look at two things: how much tip you give and whether they can reliably make a profit. When there’s congestion, you think you’re waiting in line, but it’s more like an auction… if your bid is too low, it stays hanging; if your bid is high, it might get snatched or front-run in the next second, which is both funny and frustrating.

The most annoying part is the hidden costs: for the same swap, waiting longer increases slippage, and even if it fails, you still burn gas, with your final gains gradually stolen by fees and failed transaction costs. Some people still treat on-chain data tools’ labels as gospel, but label lag and misinformation are quite common. You see a “safe address,” but end up in someone else’s trap. Anyway, when congestion hits, I’d rather do less or set a limit upfront, and consider failures as lessons learned… that’s how I’ll handle it for now.
