Today, the blockchain was congested again for a while.

That feeling of "waiting in line to enter" in the mempool really feels like rush hour on the subway:
You think clicking send is the end of it, but actually you just got a number, and then it depends on whether the miners/packagers are willing to pay attention to you.
Someone ahead of you pays extra to cut in line, someone cancels and resubmits, and your transaction gets stuck, neither going through nor dropping out.
The longer you wait, the more your patience explodes, and slippage might even give you a little extra punch…
Anyway, when there's congestion now, I prefer to slow down and split into smaller transactions, rather than going all-in at once.
Recently, Meme/celebrity calls have reignited attention, so newcomers really shouldn't chase the last wave.
When queuing on the chain, you might not even be able to see clearly what position you're in.
