Tether is centralized and pegged to the US dollars which give it some level of credibility, but the assurance is not there that it can be impossible to crashed to zero then also we can have some rare situations that can force the price to crash below recovery and one of such situation is were there is a back in tether network, this could impact its price beyond recovery level and also if the big bag holders decide to walk away pulling an exit one on the remaining tether communities.
Or a government policy could also force its price to fall below that recovery benchmark mark, so even though it seems impossible for the tether to crash to zero, it is also important we are aware of thepossibility for that happen also.
What's surprising is that in the midst of the banking crisis, Tether managed to retain its peg against the US Dollar. Other well-known stablecoins collapsed (mainly USDC and DAI) for a short period of time because of this. Either Tether is being heavily-manipulated on the market, or there's something else going on. With the issuing company (Bitfinex) adding new units of USDT to the supply, I'd take this stablecoin with a grain of salt.
You can never trust something that's isn't officially backed by the government (with the exception of Bitcoin and some other decentralized coins). If stablecoins are banned by the US government, you can say goodbye to your money for good. Who knows how long will USDT last? Just my opinion
