I just turned off the "auto acceleration" earlier to prevent my mindset from being influenced by it.

When there's congestion, your swap transaction is basically waiting in the mempool for its turn: miners/validators look at who offers the biggest tip first, who is more "attractive," if you bid low, you'll stay stuck;
If you get anxious and increase the gas fee, you might get jumped by others, and the route might even switch to a more expensive one...
Finally, if the transaction price slips, don't blame luck, blame yourself for not paying attention to slippage and the maximum waiting time.

Recently, with Meme + celebrity shoutouts, everyone rushes in a swarm, and the mempool directly hits the early peak.
Newcomers are most likely to chase orders with high slippage at the tail end of "attention rotation," resulting in you thinking you're buying on the rise, but actually you're selling for others.
Anyway, I now prefer to go slower, and if I can cancel the order, I will; don't force yourself onto this train.
