When the network is congested, your transaction is probably just standing still in the mempool, and there's no use rushing… At most, you can add a little "tip" to jump the queue, but it's not foolproof. Basically, it gets broadcasted first, and miners/validators glance at it: how much you're paying, whether it might fail, how smooth it is, then decide whether to include it in a block; if you pay less, you'll stay in line, if you pay more, it might be included in the next block. But if the chain is congested, and you wait too long, it might even be resent/replaced by your own wallet, making it feel like "I clearly clicked send, why is there no action?" By the way, I just thought of the recent NFT royalty law controversy—secondary markets all want "faster, smoother, cheaper," while creators are focused on income… It feels similar to the mempool queue-jumping mentality: everyone wants to pay less but also hopes their transaction isn't stuck. Anyway, if I’m not in a hurry, I just wait patiently; if I really need to rush, I admit I’m paying for certainty—don’t be stubborn about it.
