The one that's not backed? Whose money is supposedly in a bahamian bank run by the man who created Inspector Gadget? The one that settled with the CFTC and the NYAG for being unbacked? How you could possibly recommend this as a beacon of stability is beyond me. Especially when they don't even pay interest but you can get 5% on treasuries, so even if you just held it and they somehow never go under, you're still getting rekt.
However, USDC (or if we pretended there was anything in the vault at USDT) you don't need a blockchain lol. They could just put a portal on their website and you could just move between accounts there. But without the imaginary layer of indirection of the blockchain people would demand AML/KYC.
Those are fully centralized, fully controlled. USDT and USDC can be frozen by government entities and even by Tether themselves arbitrarily. They've done it many times.
This is a silly thing to advocate for.
> Fiat USD will always be the largest, by orders of magnitude, used currency for criminality, on the planet.
But not as a percentage of transactions. That's just a red herring. If you had the ability to wipe out a large pocket of criminality that provided little or zero real world value, why on earth wouldn't you?
What's next, comparing the size of the mob's bank accounts to the treasury as a reason not to pursue? Or because they kill less people than the army they're good to go?
