When the network is congested, your transaction is actually just waiting in the mempool... first thrown into a pile of "pending" pools, miners/validators only look at who offers the better tip, and those with lower gas get stuck repeatedly, and if they stay stuck long enough, they might be replaced by similar transactions (same nonce replacement). You keep an eye on your wallet thinking "why hasn't there been any movement," but in reality, you're being jumped in line. The most annoying thing is slippage: waiting in line means the price has already moved away, resulting in either a worse execution price or a complete failure, wasting some fees. Anyway, when I face congestion now, I split my orders and reduce aggressive bidding—better to go slow than to get snatched by bots in one go. By the way, the group is again talking about stablecoin regulation, reserve audits, and de-pegging rumors. Everyone panics and keeps clicking confirm, making the mempool look more like Spring Festival travel rush... the more urgent, the easier it is to pay tuition fees.
