The sense of "queuing" in the mempool is quite real: you click confirm, but you're just putting the transaction into a pile of unconfirmed transactions waiting for miners/validators to pick. The more congested it gets, the more it feels like rush hour—offering a lower gas/fee bid pushes you to the back, and if you're unlucky, you might get stuck for half a day, or even get dropped or remain pending until you forget about it. What's more frustrating is that some DeFi operations are interconnected; if the first one doesn't get included in a block, the subsequent ones also get stuck, making it psychologically tempting to increase the bid.

Anyway, now I stop for a second whenever I see congestion, double-check the address, amount, and signature content before sending, instead of rushing and clicking randomly. Recently, hardware wallets are out of stock again, and phishing links are everywhere—especially when the network is congested, people are more likely to take advantage of your anxiety… I’d rather go slow than turn "queuing" into "paying tuition."
