These days I've been watching the mempool queue, and after a while my eyes hurt so much I can't stand it... To put it simply, the moment you click send, the transaction isn't just "gone" once it's sent; it first has to compete in a crowd: if the gas fee is low, it's like holding a small token, and miners/validators pick and pack based on that. You can only wait there until it expires, gets bumped off, or you get tired of increasing the fee and resend. It's even more obvious during congestion; even though it's just a transfer, it feels like watching a food delivery map stuck at a traffic intersection. By the way, recently the community has been arguing over privacy coins/mixing compliance, and while I watch everyone shouting at each other, I think: even transparent queuing rules can be distorted by emotions, let alone the "invisible" part... Anyway, I try not to push through during the worst congestion now; my neck's already stiff.
