What Is a Stablecoin? USDT vs USDC vs DAI Explained
Stablecoins explained for Indian beginners: how USDT, USDC and DAI stay near $1, what they're used for, the real risks, and how they're taxed in India.
A stablecoin is a cryptocurrency designed to hold a steady value, usually pegged to a currency like the US dollar, so one coin aims to always be worth about $1. Unlike Bitcoin or Ethereum, whose prices swing wildly, a stablecoin's whole purpose is not to move much. This guide explains what stablecoins are, how the big three (USDT, USDC and DAI) keep their peg, what Indians use them for, the risks, and how they are treated for tax in India.
Key takeaways
- A stablecoin is a crypto token that tries to stay pegged to a stable value, usually the US dollar.
- USDT (Tether) and USDC are backed by reserves of cash and cash-equivalents; DAI is backed by other crypto held as collateral.
- They are used to park value, move between coins quickly, and send money without exiting crypto.
- "Stable" is a goal, not a guarantee: peg breaks, reserve doubts, and freezes are real risks.
- In India, stablecoins are Virtual Digital Assets, so gains attract a flat 30% tax and transfers a 1% TDS. The peg does not exempt them.
Why do stablecoins exist?
Crypto's volatility is a problem when you just want to hold value or move money. Imagine selling a coin at a profit but wanting to stay in the crypto system rather than cashing out to your bank. A stablecoin lets you "sit in dollars" digitally, instantly, at any hour, without going through a bank. That is why stablecoins have become the plumbing of crypto, and most trading pairs on exchanges are priced against them.
How do stablecoins stay stable?
Different stablecoins use different methods to hold their peg. The three most common Indians will meet are USDT, USDC and DAI.
| Stablecoin | Type | How it holds the peg |
|---|---|---|
| USDT (Tether) | Fiat-backed | The issuer claims to hold reserves (cash, treasuries, etc.) equal to coins in circulation. Largest and most widely used. |
| USDC | Fiat-backed | Backed by cash and short-term US government debt, with regular attestations of reserves. Often seen as more transparent. |
| DAI | Crypto-collateralised | Backed by a basket of crypto locked as collateral in smart contracts, over-collateralised to absorb price swings. Decentralised, no single company. |
Fiat-backed (USDT, USDC)
For every coin issued, the company claims to hold roughly a dollar of real assets in reserve. In theory you can redeem coins for dollars, which keeps the market price near $1. The catch: you are trusting that the reserves genuinely exist and are safe.
Crypto-collateralised (DAI)
DAI is created by locking more than a dollar of crypto for each DAI, managed automatically by smart contracts on Ethereum. No company holds cash; the code and over-collateralisation keep it stable. If the collateral crashes fast, positions get liquidated to protect the peg.
A warning about "algorithmic" stablecoins
Some coins tried to hold a peg using only clever supply-and-demand algorithms with little real backing. Several have collapsed to near zero. Treat any stablecoin promising high yields with deep suspicion. This is a classic pattern in crypto scams.
What do Indians use stablecoins for?
- Parking profits: Booking a gain into USDT to avoid volatility while staying in crypto.
- Trading: Most pairs on exchanges are quoted against USDT, so it is the base currency of trading.
- Moving value: Sending value across wallets or platforms quickly.
- Access to a dollar-like asset: Holding a dollar-pegged unit digitally.
The risks: "stable" is not "safe"
- Peg breaks (de-pegging): A stablecoin can temporarily or permanently trade below $1 if trust falls or reserves fall short.
- Reserve and transparency risk: With fiat-backed coins you must trust the issuer's reserves are real and liquid.
- Freezing and blacklisting: Centralised issuers can freeze specific addresses, so it is not truly censorship-resistant.
- Smart-contract risk (DAI): Code bugs or a collateral crash can threaten the peg.
- Yield traps: Platforms offering fat "interest" on stablecoins can fail; the coin's stability does not protect the platform holding it.
How Indians can research and get stablecoins
Compare the live USDT price and stats against the broader crypto markets to see how it barely moves versus volatile coins, and browse our forecasts for the assets you actually plan to trade. To acquire stablecoins, most Indians buy them on an FIU-registered exchange that accepts INR. Our guide to buying USDT in India safely covers the steps and pitfalls.

Tax note for India
A common myth is that stablecoins are "just dollars" and so tax-free. They are not. Stablecoins are Virtual Digital Assets, so any gain (including on swaps) is taxed at a flat 30% under Section 115BBH, and a 1% TDS under Section 194S applies to transfers above the threshold. Even swapping one coin for USDT can be a taxable event. See our crypto tax in India guide and confirm with a CA.
FAQ
Is USDT the same as US dollars?
No. USDT is a crypto token that aims to be worth one US dollar and is backed by reserves the issuer claims to hold. It usually trades near $1 but can deviate, and it is not the same as holding actual dollars in a bank.
Which is safer, USDT or USDC?
Neither is risk-free. USDC is often viewed as more transparent about its reserves, while USDT is the most widely used and liquid. Both are centralised and can be frozen. Do not put life savings into any single stablecoin.
Can a stablecoin lose its peg?
Yes. Stablecoins can and do temporarily trade below their target, and poorly backed ones have collapsed entirely. "Stable" is the design goal, not a guarantee.
Do I pay tax on stablecoins in India?
Yes. They are Virtual Digital Assets, so profits are taxed at a flat 30% and a 1% TDS applies on transfers above the threshold, just like any other crypto. Being pegged to the dollar does not exempt them.
