These days, a bunch of "large transfers" and "exchanges' hot and cold wallet movements" on the blockchain are being seen as smart money. I just find it funny to watch... When you're really rushing, mempool congestion first teaches you a lesson: a transaction isn't done just because you click it; it has to wait in line. Miners/validators prioritize those who pay higher tips. If you pay too little, it gets stuck; if you pay more, it hurts. What's more annoying is that if you change the fee or resend halfway through, the previous transaction might not be fully settled yet, and they could all get crowded together, ending up racing against yourself. To put it simply, during congestion, what you buy isn't a clear direction—it's just luck whether your transaction gets included or not. What I don't regret is... before placing an order, I always check gas and pending transactions. I'd rather miss out than force it through. That's all for now.
