Just remember: "What goes around, comes around". Tether's rise to glory could all come down to an end if something unexpected happens in the future. After all, empires don't last forever. Who would've thought a big and mighty exchange like FTX would go all the way down the drain in an instant? The same can happen with Tether in the long run. I'd proceed with caution, especially when Tether has been unable to prove its USD reserves. The company has been increasing USDT's supply without regular audits.
Since stablecoins aren't backed by the government (in this case, the US government), you can lose everything without being able to claim back your money. You're much safer saving money (Fiat) in a bank. Especially if you're an American citizen. Those living abroad would have no other option but to stick with Tether if they want the security and stability of the USD without crossing borders. The future is unpredictable, so I can only hope for the best.
