Startup Deep Dive : Unocoin — how India’s oldest crypto exchange survived a banking ban

Unocoin was buying and selling bitcoin in India three years before the country’s central bank had written a single rule about it. On 6 April 2018 that same central bank, the Reserve Bank of India, ordered every regulated lender to stop touching crypto money — and by July, Unocoin’s own count of roughly 1.3 million customers could no longer move a rupee in or out of the exchange through a bank.

The company did not shut down. It built an ATM instead, got two co-founders arrested for it, watched the case against them thrown out almost two and a half years later, and kept running long enough to still be processing an estimated $20.8 million (about ₹2 billion) a month for 2.26 million users as of June 2025, according to Unocoin’s own account to Analytics Insight. This is the story of how India’s oldest crypto exchange survived a decade in which its core product was, for long stretches, close to unbankable.

Quick facts

What they do

Unocoin runs two connected products out of Bengaluru. The first, the Unocoin app, is a retail on-ramp: it lets an ordinary saver in India convert rupees into bitcoin and roughly a hundred other tokens, hold them in a custodial wallet, and cash out again, aimed at people who want to buy a small, recurring amount of crypto the way they might a mutual fund SIP. The second, Unodax, is a live order-book exchange built for active traders who want maker-taker pricing and depth rather than a simple instant-buy screen. Since April 2025 the company has layered on Bitcoin Lightning Network payments, pitched at cheaper, near-instant settlement for cross-border transfers rather than speculative trading.

The origin

Sathvik Vishwanath spent the years before 2013 freelancing, including building scripting tools for a San Francisco-based virtual-world game studio. Getting paid meant an international wire transfer, and Vishwanath found that close to seven percent of each payment disappeared into transfer fees before it ever reached his account, as he later recounted to YourStory. That single, specific frustration — money leaking at the border — is the founding insight. It pushed him toward bitcoin as a way to move value without a bank in between, and at a Bengaluru meet-up of early Indian bitcoin enthusiasts he found three people who saw the same opening: Sunny Ray, Harish BV and Abhinand Kaseti. The four launched Unocoin in December 2013, starting out of Tumkur in Karnataka before shifting operations to Bengaluru, and by their own account had signed up roughly 3,000 registered users within the first year — a small number, but enough to make Unocoin India’s first working bitcoin exchange rather than an idea on a forum post.

The struggle years

The company’s hardest years did not come from a lack of customers. They came from the state deciding, twice, that crypto exchanges should not be allowed to bank normally.

• 6 April 2018 – 5 July 2018: the Reserve Bank of India circulated an order barring all regulated banks and payment systems from servicing crypto businesses, effective from 5 July 2018 (Cointelegraph; Business Standard). Unocoin had to suspend rupee deposits and withdrawals for its exchange customers, a group it put at around 1.3 million people, and said so publicly rather than quietly limiting withdrawals.
• 31 May 2018: rather than wait out the ban, Unocoin split off Unodax as a separate order-book trading platform, an attempt to keep active traders engaged even as fiat rails narrowed (Unocoin Blog; CryptoNinjas).
• October 2018: with banking channels closed, Unocoin tried a workaround that a normal fintech would never need — a physical ATM-style kiosk at Kemp Fort Mall in Bengaluru where customers could deposit cash directly against their exchange balance, bypassing bank transfers altogether (CoinDesk; News.Bitcoin.com).
• 23 October 2018: Bengaluru’s Central Crime Branch seized the kiosk within roughly a week of installation and arrested co-founder Harish BV, followed a day later by co-founder and CEO Sathvik Vishwanath, on charges including operating without state approval, forgery and cheating (Entrackr; YourStory).
• 8 February 2021: more than two years after the seizure, a single-judge bench of the Karnataka High Court, led by Justice H P Sandesh, quashed the criminal case against both founders, citing Supreme Court precedent on the RBI’s underlying circular (Bar and Bench; LiveLaw).

None of this was softened for customers at the time. Vishwanath later told Quartz that being arrested over a cash kiosk, for a business he considered legal, was the point at which the personal cost of running a crypto exchange in India became impossible to ignore.

The turning point

The reversal came from the Supreme Court, not from Unocoin. On 4 March 2020, ruling on a challenge brought by the Internet and Mobile Association of India, the court struck down the RBI’s April 2018 circular, holding that a blanket ban on banks servicing crypto exchanges was disproportionate given the RBI could show no demonstrated harm to the banks it regulated (CNN Business; S.S. Rana & Co.). The numbers either side of that single ruling are stark: before it, Unocoin’s roughly 1.3 million exchange customers had gone without normal banking access for about twenty-one months, since the July 2018 cutoff; within twenty-four hours of the verdict, Unocoin announced that INR deposits and withdrawals would resume, alongside rivals CoinDCX and WazirX (Unocoin Blog; News.Bitcoin.com). Vishwanath’s own line at the time — that the company would “spring back to business” — was less a marketing statement than a description of what had been paused, not destroyed, for nearly two years.

The money behind it

Unocoin has raised a reported $6.75 million across three rounds (Tracxn), a small figure next to India’s later-stage crypto exchanges, but each round mattered for a different reason:

• 10 August 2014 – seed: a reported $250,000 came in from Barry Silbert’s Bitcoin Opportunity Corp, part of Digital Currency Group. This was the first identifiable institutional money into an Indian bitcoin company, arriving before most Indian VCs would touch the category.
• 29-30 September 2016 – pre-Series A, $1.5 million: led by Mumbai’s Blume Ventures, with Mumbai Angels, ah! Ventures, Digital Currency Group, Boost VC, Bank to the Future and FundersClub also participating. Business Standard and Forbes both reported it as the largest venture round raised by an Indian bitcoin startup at the time; Blume’s Karthik Reddy said the firm saw Unocoin as “the leading Bitcoin company in India.”
• 8 October 2020 – targeted Series A, up to $5 million: led by Tim Draper’s Draper Associates, alongside XBTO Ventures and 2020 Ventures. Unocoin said $3.6 million had come in by the announcement date, with the round designed to value the company near $20 million if fully subscribed (CoinDesk; YourStory; FinTech Futures). The round landed within days of the Supreme Court’s ban reversal and gave Unocoin a marquee US investor’s name at a moment when Indian banks were still cautious about crypto clients.

No later priced round has been publicly reported since 2020, and Unocoin has not disclosed an IPO timeline.

How it makes money

Unocoin earns the way most spot crypto exchanges do: a cut of every transaction, not a management fee on holdings.

• Instant buy/sell fees on the retail app: around 0.5% on bitcoin and roughly 0.6-0.7% on ether and USDT trades, per fee data compiled by TradersUnion — the spread is widest on the assets retail users trade least often.
• Maker-taker fees on Unodax: at launch in 2018 the order-book platform charged makers 0.4% and takers 0.6%, a structure designed to reward traders who add liquidity to the book rather than just take the best available price.
• Ancillary services: a systematic buying plan (Unocoin’s version of a crypto SIP) and wallet custody, both of which ride on the same trading-fee mechanics rather than a separate subscription charge.
• Newer, fee-light moves: zero-fee bitcoin withdrawals introduced in September 2024 and Lightning Network payment rails from April 2025 trade near-term fee income for stickiness and lower-cost settlement — a bet that cheaper rails bring in more volume than they give up in per-transaction margin.

The part people tend to get wrong is assuming a crypto exchange’s revenue tracks the price of bitcoin. It tracks trading volume instead, and volume is far more sensitive to regulation and tax policy in India than to price alone, as the numbers below show.

The numbers

Unocoin Technologies Private Limited is closely held, and its full profit-and-loss statement is not public — Tofler and Zauba Corp, which draw on the company’s Ministry of Corporate Affairs filings, keep detailed year-by-year figures behind a paid subscription. What is disclosed, and verifiable, is enough to show the shape of the business rather than its precise scale:

Read together, this is a company whose revenue fell sharply and whose losses deepened in the fiscal year that immediately followed India’s April-July 2022 crypto tax changes (below), and whose scale two years later still sat in a wide single-digit-to-low-double-digit-million-dollar revenue band. Paid-up capital stood at ₹1.7 crore against authorised capital of ₹2.5 crore as of Tofler’s most recent snapshot, consistent with a business that has not raised large fresh equity since 2020. Any more granular figure — an exact rupee-crore revenue or loss number for FY2023, FY2024 or FY2025 — sits behind Tofler’s and Zauba’s paywalls and is not independently confirmed elsewhere, so it is left out rather than estimated.

Where the money comes from

Unocoin’s volume splits along two lines rather than a formal reported segment breakdown, since the company does not publish geography- or product-wise revenue.

• By product: the retail Unocoin app (small, recurring buys, SIP-style investing) versus Unodax (active, order-book traders) — a deliberate split made in 2018 specifically so the two very different user types would not compete for the same interface (Unocoin Blog).
• By geography: overwhelmingly domestic India, unlike larger rivals such as CoinDCX, which expanded internationally by acquiring Dubai-based BitOasis in July 2024 (TechCrunch/CB Insights reporting on the sector). Unocoin has not announced a comparable cross-border acquisition.
• By use case, newest layer: Lightning Network payments launched April 2025 target cross-border remittance and payments rather than pure speculation — the surprise is that India’s oldest “buy and hold bitcoin” exchange is now positioning part of its business around bitcoin as a payment rail, not an asset.

The company reported 2.26 million cumulative users and roughly $20.8 million (about ₹2 billion) in monthly transaction value as of June 2025 (Analytics Insight interview with Sathvik Vishwanath) — figures that describe activity, not audited revenue, and should be read as company-stated rather than independently verified.

The risks

• Tax policy has already cut trading volume once, sharply. India’s 30% tax on virtual digital asset gains plus a 1% TDS on transactions above ₹10,000, effective April and July 2022 respectively, coincided with reported trading-volume declines of 41-72% across major domestic exchanges within days to weeks (CoinDesk; Business Today, two independent reports). Unocoin’s own CEO said liquidity-provider margins had become “very thin” as a result. This is a structural, ongoing risk rather than a one-time shock: the framework has not been rolled back as of 2026.
• Banking access has been cut before and could be again. The 2018-2020 RBI ban shows the mechanism concretely: a single regulatory circular froze INR rails for an estimated 1.3 million Unocoin customers for roughly twenty-one months, reversed only by a Supreme Court ruling rather than a change of regulatory heart. India still has no dedicated, standalone crypto law as of 2025, leaving exchanges dependent on how existing tax and banking rules are applied rather than a settled statute.
• Scale mismatch against better-funded domestic rivals. CoinDCX has raised a reported $244.4 million and was valued near $2.45 billion following an October 2025 Coinbase investment; CoinSwitch has raised a reported $300 million at a reported $500 million valuation as of April 2021 (CB Insights; TechCrunch). Unocoin’s reported $6.75 million raised and roughly $20 million last-known valuation put it in a fundamentally different capital league from the exchanges it competes with for the same retail Indian user.

The takeaway

Unocoin’s history argues that being first is not the same as being biggest, and that surviving a hostile regulatory swing is its own kind of business model. The company never had the capital of CoinDCX or CoinSwitch, and it spent a chunk of its most important growth years fighting a banking ban and a criminal case rather than scaling a product. What it kept was continuity: it is still the same founders, running the same core idea, more than a decade after a freelancer’s frustration with wire-transfer fees started it. The transferable lesson is not “move fast” — it is that in a business built on a regulator’s tolerance, staying open through the years when the rules are hostile can matter more than growing fast in the years when they are not.

Frequently asked questions

Is Unocoin India’s oldest crypto exchange?

Yes, by most contemporaneous accounts. It launched in December 2013, and Business Standard’s 2014 profile of the founders already referred to it as India’s first Bitcoin exchange.

Did the 2018 RBI ban shut Unocoin down?

No. Unocoin suspended rupee deposits and withdrawals from July 2018 but kept operating, including launching the Unodax trading platform and a cash-deposit ATM kiosk, until the Supreme Court struck down the ban on 4 March 2020.

Were Unocoin’s founders actually arrested?

Yes. Co-founders Harish BV and Sathvik Vishwanath were arrested in October 2018 by Bengaluru’s Central Crime Branch after the company installed a bitcoin ATM-style kiosk without state approval. The Karnataka High Court quashed the case against both in February 2021.

How much funding has Unocoin raised, and who backs it?

A reported $6.75 million across three rounds, according to Tracxn: a 2014 seed from Barry Silbert’s Bitcoin Opportunity Corp/Digital Currency Group, a 2016 pre-Series A led by Blume Ventures, and a 2020 Series A led by Tim Draper’s Draper Associates.

Is Unocoin profitable?

Not as of its most recent disclosed filing. Tofler’s data, sourced from the company’s Ministry of Corporate Affairs filing, shows a net profit margin of -192.2% for the year ended 31 March 2023, with revenue down 47.7% year-on-year in the same period.
