Just now, watching the mempool queue made me a bit impatient: the moment you click confirm is not just "sent and done," more like entering a number machine. First, it broadcasts to the node, then it gets crowded in the pool with a bunch of transactions going in the same direction, competing over who is willing to pay higher fees; when congestion occurs, miners/validators will prioritize packing the "more valuable" ones, your transaction might get stuck, replaced, or even expire and become invalid, and the wallet is still spinning around... frankly, all the anxiety is written into those few minutes of delay.

Recently, I also heard that in some regions, taxes are increased and compliance is tightened and loosened, causing everyone’s deposit and withdrawal expectations to change, and the on-chain queue immediately shifts: some are eager to withdraw, some are eager to transfer, mempool is like a mood thermometer. Now, before I see a large transfer across bridges, I prefer to check the queue and whether the same address is repeatedly increasing the fee, better to be slow than to gamble on luck in congestion.
