USDT is the most trusted cryptocurrency among others. It's even safer than Bitcoin iteslf. Usually, they call Bitcoin gold, but I'd say that USDT is real gold. It's stable so if you want to have smth constant in crypto, hold this stablecoin.
What's the benefits to hold stable coins? It’s ridiculous opinion i think. How is it compare with BTC? I do not think stable coins are most legitimate even though you mentions it better than BTC. No way to keep too much trust in Tether & all of stable tokens. But among of them i am going to prefer to USDT. It’s unfair to making comparison with BTC.
