Tether Definition: Tether is the largest stablecoin with 100+ billion in circulation, pegged 1:1 to US Dollar through backing claims (Tether asserts it holds equivalent USD reserves). USDT is issued on multiple blockchains (Ethereum, TRON, Polygon, etc.) as ERC-20 and similar tokens. Tether is the foundational stablecoin in crypto markets — the trading pair against which most altcoins are quoted (not USD, but USDT). Tether has faced continuous controversy regarding backing: audits are infrequent, reserve composition is unclear, and regulators have questioned whether backing is sufficient. Despite regulatory scrutiny, USDT remains dominant due to liquidity (impossible to dislodge) and Tether’s willingness to issue on every blockchain (distribution advantage). USDT is considered “too big to fail” — if Tether collapsed, crypto markets would face systemic collapse.
What Is Tether?
Tether is stablecoin. Unlike Bitcoin’s volatile $26,000–$68,000 range, Tether’s price maintains ~$1 through backing — Tether claims for every USDT in circulation, it holds equivalent USD in reserves.
USDT enables traders to exit volatility without leaving crypto: sell Bitcoin for USDT (~$1 value), hold stably, re-enter without bank transfers. This is USDT’s killer app.
How Tether Works
Tether operates as stablecoin issuer:
- Reserve backing: Tether claims to hold USD, Treasury securities, and commercial paper backing USDT. For every $1 billion USDT issued, $1 billion reserves supposedly exist.
- Issuance: When users deposit USD with Tether, Tether issues equivalent USDT. When users withdraw, Tether redeems USDT for USD.
- Cross-chain deployment: USDT is issued on Ethereum (as ERC-20), TRON (as TRC-20), Polygon (as ERC-20), Solana, and 10+ other blockchains. This multi-chain presence is distribution advantage.
- Price stability: If USDT trades below $1, arbitrageurs buy cheap USDT and redeem for $1 USD, pocketing the spread. This buying pressure pushes price back to $1. Mechanism maintains peg.
Worked example: You send $100,000 USD to Tether. Tether issues 100,000 USDT (1:1 ratio). You transfer USDT to friend on TRON chain (instant, $0.01 fee vs. $30 wire transfer). Friend redeems 100,000 USDT for $100,000 USD from Tether. Total time: 5 minutes. Traditional wire: 2–3 days. Cost: $0.01 vs. $30. Winner: USDT.
Why Is USDT Important for Traders?
USDT is the crypto market’s lifeblood. Most altcoins trade against USDT, not USD. If USDT’s backing fails, crypto market suffers systemic collapse (participants cannot exit to “stable” value).
USDT is not investment (no growth potential, always $1). USDT is settlement layer — you hold it temporarily between trades or to wait for market opportunities.
On PrimeXBT, USDT is unavoidable — all CFD profits are nominally in USDT or equivalent. USDT’s stability is foundational to crypto market operations.

- Tether (USDT) is the largest stablecoin with 100+ billion in circulation, pegged to US Dollar through claimed reserve backing.
- USDT’s killer app is fast, cheap settlement — traders can exit crypto volatility without bank transfers ($0.01 cost vs. $30 wire transfer).
