These days, the blockchain is congested again like rush hour. I see a bunch of transactions queued up in the mempool, like taking a number at the door. When you click confirm, it's not actually "immediate execution," but rather your order is first thrown into the pool, waiting for miners/validators to pick. Whoever offers the higher tip or has more attractive "conditions" usually gets packed first; if you offer too little, it stays hanging, and even if the price or routing changes, your transaction might get stuck for half a day and ultimately fail, wasting some fee—pretty frustrating.

Especially now, attention shifts quickly; a meme or a celebrity's comment can pull new users in, and everyone rushes in like a swarm, causing the chain to instantly become overcrowded. Veteran players say not to take the last step, and I agree. Honestly, you're not competing with the market in speed; you're competing with the congestion of the entire chain and others' bids. My approach is simple: don't rush. First, observe the congestion, avoid using "mindless maximum slippage," and prefer to miss out rather than get stuck paying tuition repeatedly in the queue. Anyway, the lighthouse doesn't report specific prices, only reminds you: when the queue is long, rushing in isn't necessarily brave; it might just be more expensive.
