Earlier quoted context omitted.
Stablecoins are more stable than BTC and ETH, so they have quite a bit more utility than one might think, given your comment.
Nope, what are they backed by? Nothing other than 'attestations' and 'trust me bro'. Tether is a fraudulent ponzi, USDC is not stable and is backed by meaningless attestations, Luna is, well gone all the way to the floor. Even if we take USDC on ETH there exists the uncontrollable volatile gas fee tax which is pointless for micropayments. 'Stablecoins' (or 'stabletokens' are inherently fraudulent and dead on arrival…
Stablecoins don’t need to be backed by anything to be stable. I agree with most of what you say, but that doesn’t actually refute my point that stablecoins are, in fact, more stable than most cryptocurrencies. They are more than stable enough to use for a payment aggregation layer for a few days.
I even agree with you about Tether being a fraud; I still use USDT every day (with that knowledge) because it is, well, stable. One day it won’t be, but most days, it is.
