I like Matt, but that's a misleading comparison. You can't compare banks with non-banks, since, again, banks have the special regulated right to _create money out of thin air_ and put it on their balance sheet (or if you prefer the fractional reserve metaphor, they can double count your deposit -- lending it out while pretending they still have it for you).
Here's a way to reality check the difference: if 90% of Tether holders redeem their deposits tomorrow, 100% of them will get their money back and Tether Ltd will remain 100% solvent and liquid. If 90% of JPMC depositors redeem tomorrow only 10% of them will get their money back and JPMC will be insolvent.

Where would you rather have your money?
