Is USDT Legal? A Comprehensive Analysis of Its Legal Status, Controversies, and Regulatory Landscape

“Is USDT legal?”
This is one of the most common questions asked by many people who have just come into contact with cryptocurrencies. Tether, USDT, as the world's largest stablecoin by market capitalization, has a daily trading volume of more than $500 billion and is supported by almost all cryptocurrency exchanges, but its legality has been controversial.
Some say it's a “grey zone,” some say it's “legal but controversial,” and some worry “one day the government won't suddenly ban it.” In fact,USDT'S LEGALITY ISSUES ARE MORE COMPLEX THAN IMAGINED— It is not simply “legal” or “illegal”, but “different legal status in different countries”.
This article will give you a full breakdown of USDT's legal status in Taiwan and around the world, historical disputes, regulatory status, and compliance risks to be aware of when using it.
1. What is Tidal Coin (USDT)? Basic knowledge
Before discussing legality, first understand the nature of USDT.
Basic information about USDT
Tether, USDT is a “stablecoin”, the price is anchored to the US dollar, 1 USDT = 1 USD.
Core Features:
- Issuer: Tether Limited (Registered in the British Virgin Islands)
- Release date: 2014 (original name Realcoin)
- Market capitalization: approximately $1,100 billion (No. 1 in the global stablecoin market in February 2025)

USDT Operation Logic
Tether claims that for every 1 USDT issued, it holds $1 of equivalent value (or equivalent assets) as reserves. Users can:
- Deposit USD into Tether Corporation and get equivalent USDT
- Trade in the market with USDT
- Redeem USDT for USD when needed
In theory, this mechanism guarantees USDT's 1:1 anchoring relationship with the US dollar. But in practice,THE TRANSPARENCY AND AUTHENTICITY OF RESERVES HAS BEEN THE MOST CONTENTIOUS。

4. the five historical controversies of USDT
“Legal” for USDT does not mean “no problem”. It has always been accompanied by various controversies.
Dispute 1: Reserve Ambidities
Core issues: Does Tether really hold enough reserves?
2017-2019: Completely opaque
- Tether Claims 100% USD Reserves, but Never Provides Audit Report
- Exploded in 2019, the reserve is only 74%
2019—2021: Step-by-step improvement but still insufficient
- Recognized reserve is not 100% USD cash
- Including commercial notes, loans, other assets
- “Poor quality assets” overrepresented
After 2021: Partial Transparency
- Commence regular publication of reserve fund composition
- 2024 data show: Approx. 85% cash and equivalents, 15% other assets
- However, the full independent audit report is not available
Dispute 2: Reimbursement of reserve
2018-2019: Bitfinex Default Case
- Tether's sister company Bitfinex loses $8.5 billion
- Tether Borrowed Reserve Funds to Bitfinex for Redemption
- Violation of the promise of “there is $1 support for every USDT”
- Finally Settled with New York State Attorney and fined $1,850M
This case proves that Tether did indeed overspend reserves, seriously hitting trust.
Controversy 3: Manipulating Bitcoin Prices
2017-2018: Accusations of Academic Research
- STUDY BY UNIVERSITY OF TEXAS SCHOLARS POINTS OUT THAT BITCOIN SURGE IN 2017 IS RELATED TO USDT SURGE HIGHS
- Doubting Tether with Blank Banknotes, Pushing Bitcoin Price Up
- Tether denied, but could not fully clarify
The dispute has not been settled until now, but one questions the impact of USDT on the market.
Controversy 4: Lack of Independent Auditing
Core issues: Why isn't Tether looking for four major accounting firms to do independent audits?
- Formerly partnered with Friedman LLP in 2018, but ended in mid-term
- Cooperated with BDO Italia since 2021, but only provides a “proof report”, not a full audit
- Not one of the four major accounting firms (PWC, Deloitte, KPMG, EY) is willing to audit Tether
The lack of independent auditing has left outsiders doubting the veracity of reserves.
Dispute 5: Used for Money Laundering and Illegal Activities
Question: USDT's anonymity and cross-border properties are abused
- 2023 UN report: North Korean hackers launder money with USDT
- Multiple Ransomware Cases Require USDT to Pay Ransom
- Underground economy, illegal trading heavily uses USDT
Tether emphasizes that KYC/AML measures have been strengthened, but the problem is difficult to eradicate.

- May 2022: USDT Drops Once to $0.95 During Luna Crash
