Today I kept an eye on the mempool, like watching a rush hour subway station line... The moment you send it out, it’s not actually "confirmed" yet, just holding your spot in line. It’s even more obvious during congestion: miners/validators prioritize transactions with higher fees, so your transaction might hang at the end of the queue for a long time, or even get dropped, stuck as "pending," making wallet holders anxious as they see unconfirmed transactions.

I usually do two things: either add a bit more fee for certainty, or just cancel and resend, don’t tough it out. Especially now, everyone is testing incentives on testnets, gambling on points, guessing whether the mainnet will issue tokens, and when the chain heats up, the queue immediately lengthens... To be honest, no matter how good the model is, it can’t control this kind of emotional traffic. It’s more realistic to keep your own situation in check first.
