I'm not very good at explaining those very academic principles, but I really have a strong feeling about the "queuing" in the mempool... When there's congestion, the transaction you send out is basically like rushing to the long chairs in the lobby: miners/packagers will first pick those with higher tips, and the rest awkwardly stand in place, stuck for a long time, thinking they've gone invisible on the chain. What's even more frustrating is that I, who love to leverage, clearly click on close position/hedge, but end up being the first to be called when the liquidation line is reached, and my mood just drops to the edge. Recently, I’ve seen on-chain data tools and tagging systems being criticized for lagging and misleading, which is actually normal... If you keep an eye on it, it shows "confirmed/safe," but the mempool might still be fighting. Anyway, when there's congestion, I just play it honest now, prefer to do less, or pay a little extra fee for peace of mind.
