USDT’s unique feature is the fact that its value is guaranteed by Tether to remain pegged to the U.S. dollar. According to Tether, whenever it issues new USDT tokens, it allocates the same amount of USD to its reserves, thus ensuring that USDT is fully backed by cash and cash equivalents.
The famously high volatility of the crypto markets means that cryptocurrencies can rise or fall by 10-20% within a single day, making them unreliable as a store of value. USDT, on the other hand, is protected from these fluctuations.
This property makes USDT a safe haven for crypto investors: during periods of high volatility, they can park their portfolios in Tether without having to completely cash out into USD. In addition, USDT provides a simple way to transact a U.S. dollar equivalent between regions, countries and even continents via blockchain — without having to rely on a slow and expensive intermediary, like a bank or a financial services provider.
However, over the years, there have been a number of controversies regarding the validity of Tether’s claims about their USD reserves, at times disrupting USDT’s price, which went down as low as $0.88 at one point in its history. Many have raised concerns about the fact that Tether’s reserves have never been fully audited by an independent third party.
