Every time the network gets congested, I just stare at the mempool in a daze, like watching a bunch of people squeezing onto the subway... You submit your transaction and wait in line, if you give too little gas, it slowly moves back, and if you're unlucky, you might even get pushed out of view (which is basically just pending all the time). Even worse, if you're in a hurry, you click "accelerate," which is essentially paying a higher fee to cut in line. Honestly, at this point, you think you're "placing an order," but you're actually participating in an auction. By the way, recently those on-chain data tools and tagging systems have been criticized for being laggy, and I can understand: the people in the queue are constantly changing, and watching the "explanations" on the screen can easily lead you to follow the rhythm. Anyway, when there's congestion now, I just try small amounts first—don't get too excited and end up being the last one.
