Just now, I wanted to move my position on the chain, but when I checked, there was a long queue in the mempool. My mood was a bit like squeezing into the subway during rush hour: you think clicking it will send the transaction, but actually you're just standing at the door waiting. During congestion, transactions are first "temporarily stored," and miners/validators prioritize packing those with higher fees. If you pay less, you stay stuck, and you might even get replaced by a later transaction with the same nonce. Anyway: it’s not necessarily a failure, but it will keep showing as "pending," making you more anxious the more you refresh.

So now I basically avoid moving if I can, and if I really need to send a transaction, I plan ahead: either honestly pay a reasonable fee or wait until the network isn’t congested. Especially recently, with Meme/celebrity hype and attention shifts, many people rush in for fear of missing out, only to get stuck in the mempool watching others go first, and end up taking the last shot… A veteran tip: don’t let “queue anxiety” force you into reckless actions.
