Do you think clicking "Confirm" means the transaction goes through immediately?

Actually, most of the time it just goes into the mempool queue: if you set a low gas fee, you'll be pushed to the back, and during congestion, it might even be replaced by someone else with the same nonce, or get stuck for half a day and finally be dropped by the node... You only see "pending" on your side; on the blockchain, miners/packagers are choosing the more profitable transactions. To put it simply, if you're in a hurry, just raise the gas or directly accelerate/cancel; if you're not in a rush, don't keep refreshing and stressing yourself out. Recently, the group has been talking about stablecoin regulation, reserve audits, and de-pegging rumors again. I see everyone gets emotional and wants to "run first," but as a result, everyone ends up in the same wave, the mempool gets clogged, the more anxious you are, the slower it gets. Anyway, I prefer to think through the transaction path and rollback options clearly before clicking.
