Currently USDT has a freeze-function on all platforms except one - Liquid.
Hmmm, that is interesting.
I didn't know that L-USDT coins can't be frozen, and that is a good thing, but Liquid is Federated Network, so I don't fully trust them.
Still is it is solid alternative, especially knowing that Liquid transactions are confidential.
Good luck to them, but I have zero hopes coming from Africa, and I am sure they are all using custodial wallets.
