It cannot be denied that Tether is the best investment of all time, where Tether is very stable and its value always follows USD movements, and Tether is an altcoin that can be a security for crypto assets, where if the crypto market is experiencing chaos or the price value is very unstable, then tether could be the best solution to be able to secure your crypto assets, namely by exchanging your assets to tether.
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.
