What is Tether (USDT)?
USDT is a cryptocurrency known as stablecoin , which means that its value is stable and anchored to a reference asset. In the case of USDT, this asset is the US dollar, and the ratio is $ = 1 USD. The purpose of this currency was to create the "digital money of the Internet," allowing users to quickly trading in the blockchain ecosystem, without being affected by the volatility characteristic of other cryptocurrencies.
Key Functionalities:
- Protects the value of your investments against market fluctuations.

Who are the founders
USDT was launched in October 2014 by Brock Pierce, Reeve Collins and Craig Sellars under the initial Realcoin . Built on the basis of the Omni Layer protocol of the Bitcoin blockchain, Realcoin was renamed Tether in November 2014.
In January 2015, USDT was integrated into Bitfinex, one of the largest crypto exchange platforms, which has contributed significantly to increasing USDT use and popularity.
How it works
USDT works on the following principle:
- For each USDT unit issued, an equivalent amount of $ 1 in a bank account is theoretically reserved.
- This mechanism ensures the stability of USDT price, which means that it does not fluctuate like other cryptocurrencies.
Why is it unique
USDT has been differentiated from other cryptocurrencies through its excellent stability and versatility characteristics. More accurate:
- It is a unique digital asset due to its direct support of equivalent reserves in US dollars.
- Along with USDC, USDT has the largest trading volume of all cryptocurrencies, being used for liquidity and hedging in crypto markets.
- It can be used for both payments and rapid exchanges between various cryptocurrencies.
Another important aspect is that USDT is widely accepted as a payment method and value deposit within the blockchain ecosystem, which reduces the risks associated with market volatility.
How to secure
Tether Security is guaranteed by:
- Proof of Reserves ( Proof of reserves ): Tether claims that all the coins emitted are covered by 100% valuable assets. These reserves include Fiat money, government securities, gold and other safe investments.
- Multiple blockchain : USDT is issued on several networks, protected by consensus mechanisms of these blockchains, such as proof-office (bitcoin) or proof-of-stake (Ethereum, throne). The security of these blockchain contributes to the security of USDT transfers.
- Periodic audition : Even though there have been transparency controversies, Tether works regularly with several audit companies to provide attestations to his reserves.
- Offline storage (Cold Storage): Financial scholarships and institutions that manage large amounts of USDT often use offline storage to protect funds from online attacks.
