Looking at my situation, I have a bunch of UTXOs that are .0004 BTC and up, so my fears of everything turning to dust are not as dire as I thought.
Before I opened this topic, it would have been dust:
Not so long ago, more than 600 Satoshis/byte was needed to have any chance at a fast confirmation.
If that happens again, you'll just have to wait it out.
I am thinking of holding out waiting for something like a fee rate of 6 sats and just get it done. There are 3 UTXOs that are below .0004, one is .00008, I'll make sure I don't burn it.
As long as you're not in a hurry, you're good.
Exchanges tend to overcharge their customers, so it's not like they care about being thrifty.
Many companies overcharge their customers, but wasting money still costs them money.
