Earlier quoted context omitted.
The thing is tether is pegged. I think the point you're missing here is that there is no logical basis for the "pegging". It's pegged because crypto exchanges play along with the pegging fantasy.
Well it’s supposed to be pegged to the dollar by maintaining USD deposits. Nothing here or that I’ve yet seen indicated that hasn’t been happening. Banks are worse anyway, all banks function on fractional reserve, but we don’t immediately call them scams.
US (and many other) Banks have capital requirements, regulations, regulators, and insurance that covers the deposits!
