USDT is in my opinion worse even than Fiat. There is absolutely NO point in holding a Cryptocurrency that is SO Centralized and that offers sometimes even less advantages than using Fiat directly. Besides being able to hold on to the Fiat value of your Portfolio, to me they are useless and sense lacking.
Too many Stablecoins became unstable all of a sudden in the past years. This should have been a giant warning sign for any body who contemplates doing the same and trying to use Stablecoins because 'even if it happens, what are the chances it happens NOW'.
Imagine having to transfer 100 thousand Dollars through USDT and they decide to crack down on all Wallets containing more than 50 thousand Dollars by freezing them and initializing an investigation. You are one of those in the exact middle of that with no idea what is about to happen. So you all of a sudden wake up with your Dollars seized or frozen for no reason.
Why would I want to live under this constant fear. I want safety, not fear. Bitcoin offers that.
