Sometimes looking at the blockchain is like watching the subway turnstiles during rush hour; a bunch of transactions are lining up in the mempool. Clicking send doesn't mean you're getting on the train immediately. First, your transaction enters the pool, waiting for miners/block producers—if you pay too little, you'll get pushed back; during severe congestion, your transaction might be repeatedly replaced (your fee outbidding your own previous one), or simply expire, showing as pending in your wallet but nobody's actually processing it. Not to mention some bots are watching nearby, ready to cut in line—though you're operating normally, you might get front-run or sniped, making the experience feel quite mystical.

So now I pay more attention to whether the congestion is "genuine demand" or just "attention being spammed." Recently, with social mining and fan tokens, they say attention equals mining... It sounds lively, but when queuing on-chain, ultimately, those willing to pay set the rules; others can only watch. Anyway, I first check how many pending transactions there are before placing an order—if there's no rush, I wait; if urgent, I accept the cost.
