Watching the mempool during congestion is really quite frustrating. Your transaction isn't just "sent and done"; it's more like being constantly cut in line in a queue: first by the priority of the package (basically the gas you pay), then by whether there's enough block space, and it might also get stuck if there's a previous transaction with the same nonce. The whole chain can become immovable. I used to get impatient and keep increasing the fee, but even a failed transaction still burns money, and my mood would just explode... Now I’ve gotten used to managing the nonce carefully. If there's a cheaper way to do it, I won't force it. If I really want to compete, I just pay once and get it done properly; otherwise, it’s just back-and-forth tinkering.

Recently, a bunch of AI agents are hyping up automated trading, but I see many just "automatically click confirm" for you, with no regard for safety or rollback. Don’t believe the hype—check the settlement first. When transactions are really queuing up, even machines have to accept their fate.
