Today the network was congested again, my 0.003 transfer got stuck in the mempool, waiting in line for about 90 seconds, and the mental stress was worse than trading... Basically, sending a transaction doesn't mean it gets on the chain immediately, it just gets queued. The more congested it is, the more it feels like抢座: whoever offers a higher tip (gas) gets packed first, and those with lower tips can only wait at the back, or even get bumped out and have to start over.

Recently, everyone has been complaining that validators/miners are making too much profit, and that MEV is making the ordering unfair. I can understand, especially when I see a few transactions inserted before and after mine, feeling like being cut in line. Anyway, my current rule is: if it's urgent, add more gas; if not, cancel the transaction, close the computer, and go for a walk—don't stare at it obsessively.
