Tether (USDT) stands as the pioneer and most widely adopted stablecoin in the cryptocurrency space. Designed to bridge traditional fiat currencies with blockchain technology, USDT maintains a 1:1 peg to the US dollar (and later, the euro). Despite its dominance among stablecoins, Tether has faced persistent scrutiny regarding its reserve backing and operational transparency.
Quick Facts
- Ticker Symbol: USDT
- Maximum Supply: Unlimited
- Protocol: Proof-of-Work (Omni Layer)
Historical Background of Tether
Emerging in 2014 as Realcoin, Tether rebranded later that year to address the need for stability in the volatile crypto market. Its founders leveraged the Omni Layer, a protocol built atop Bitcoin’s blockchain, to create a token pegged to the US dollar. Key milestones:
- 2014: Launch as Realcoin, later renamed Tether.
- 2017: Expansion to Ethereum’s ERC-20 standard, enhancing compatibility.
- 2019: Market capitalization surged to $3 billion, cementing USDT’s role as the go-to stablecoin.
Tether’s ecosystem grew alongside Bitfinex, a major crypto exchange founded by the same team. This relationship, however, later sparked controversy over conflicts of interest.

Criticisms and Controversies
1. Reserve Transparency
Tether initially claimed 1:1 USD backing but revised its terms in 2019 to include "other assets" like loans (e.g., $900M to Bitfinex). Independent audits remain scarce, fueling skepticism.
2. Market Manipulation Allegations
Analysts accused Tether and Bitfinex of inflating Bitcoin prices in 2017 via wash trading and front-running. While unproven, regulatory scrutiny prompted retreat from US markets.
3. Regulatory Risks
Centralized control contrasts with crypto’s decentralized ethos, making Tether vulnerable to legal action or bank failures.
