Gemini: The Complete Guide

What is Gemini?

Gemini is a New York based cryptocurrency exchange and custodian founded in 2014 by the identical twins Cameron and Tyler Winklevoss. It is best known for two things: an early, deliberate bet on regulation, and a series of high-profile controversies that tested whether that regulatory posture actually protects customers.

Unlike most exchanges, which operate as ordinary money-services businesses or from offshore jurisdictions, Gemini is chartered as a limited-purpose trust company by the New York State Department of Financial Services (NYDFS). That charter makes it a fiduciary, legally obligated to hold customer assets in a specific way and to maintain capital reserves. In September 2025 its parent company, renamed Gemini Space Station, went public on Nasdaq under the ticker GEMI.

The Gemini short answer

Gemini is a regulated US exchange that trades safety and compliance for breadth. You get a New York trust charter, audited custody, a transparent dollar stablecoin (GUSD) and a public-company balance sheet. In return you accept a smaller asset menu than Coinbase or Binance, thinner liquidity on some pairs, and the memory of the 2022 Earn freeze that locked up customer funds until a bankruptcy paid them back. It is a reasonable home base for cautious US users, not a venue for exotic tokens or maximum yield.

How it works and what Gemini offers

Gemini is a suite of products stitched around one custody engine. As of mid-2025 the platform held more than 21 billion dollars in assets across roughly 549,000 retail users and about 10,000 institutions; by later in 2025 crypto under custody had surpassed 30 billion dollars. The main pieces:

Spot exchange and ActiveTrader

The consumer app and website let you buy, sell and convert around 70-plus crypto assets with a few taps. Power users switch to ActiveTrader, a full order-book interface with limit, market, stop-limit and maker-taker pricing. Same assets, same custody, dramatically lower fees. The single most valuable tip for any Gemini user is to trade through ActiveTrader rather than the simple flow.

Gemini Custody

This is the institutional cold-storage product and arguably the company's crown jewel. Assets sit offline in segregated accounts under the trust charter, with governance controls, insurance and SOC audits. In 2025 Gemini agreed to integrate custody and staking with Nasdaq's Calypso collateral-management platform, and Nasdaq took a 50 million dollar stake via private placement around the IPO.

GUSD, the Gemini Dollar

A US-dollar stablecoin launched in 2018, one of the first to be regulated by NYDFS. Each token is meant to be backed one-to-one by dollar-equivalent reserves.

Gemini Credit Card

A Mastercard that pays crypto rewards on spending, settled into your Gemini account. It became a genuine growth engine: 2025 card transaction volume topped 1.2 billion dollars and card net revenue was about 33 million dollars, up roughly 185 percent year over year, and it kept accelerating into 2026.

Staking, OTC and prediction markets

Gemini offers custodial staking on proof-of-stake assets, an over-the-counter desk for large trades, and, new in 2026, a prediction-markets product that added a small slice of first-quarter revenue in its first full quarter. Nifty Gateway, its NFT marketplace, was wound down in early 2026 as part of a cost-cutting round that also cut roughly 30 percent of staff and exited the UK, EU and Australia to "double down on America."

Token, fees and economics

Gemini has no exchange "governance token." The asset that matters here is GUSD, plus the fee schedule.

GUSD tokenomics

GUSD is a fiat-collateralized stablecoin, not an algorithmic one. Its supply expands when users mint dollars into tokens and contracts when they redeem. Reserves are meant to consist of cash in FDIC-insured omnibus bank accounts, money-market funds, and short-dated US Treasury bills (three months or less to maturity), held at institutions such as State Street and Goldman Sachs Asset Management, with the cash portion potentially eligible for FDIC pass-through insurance. An independent accounting firm, BPM LLP, publishes monthly reserve attestations, including an examination on a randomly selected business day each month.

The honest caveat: GUSD is a minnow. Its circulating supply sits in the tens of millions of dollars (around 39 million as of 2026), a tiny fraction of USDT or USDC. That means thin secondary liquidity and limited DeFi integration. It is transparent and regulated, but it is not a deep-market stablecoin.

Fee schedule

There are two very different cost structures, and choosing the right one matters more than the exact numbers.

The simple flow is expensive by design. A 200-dollar app purchase can cost close to 2 percent all-in once the convenience and transaction fees stack. The same trade on ActiveTrader as a maker can cost a fraction of that.

The public company

Gemini Space Station priced its IPO at 28 dollars per share in September 2025, above its marketed 24-to-26-dollar range, valuing it around 3.3 billion dollars and raising roughly 426 million dollars from about 15.2 million shares. The book was reportedly heavily oversubscribed; the stock opened near 37 dollars and closed its debut up about 14 percent, near 32 dollars. The enthusiasm did not hold. By early 2026 GEMI had fallen far below its offer price, down roughly 80 percent from its debut peak, and shareholders filed suit as several executives departed. The financials explain the mood: revenue grew about 26 percent to roughly 180 million dollars in 2025, but the company posted a net loss of about 583 million dollars, and Q1 2026 revenue of about 50 million dollars (up 42 percent year over year) still came with a per-share loss. Gemini is a regulated business, growing on the top line but currently deeply unprofitable.

Security, trust and track record

This is where an honest guide has to hold two ideas at once.

On the positive side, Gemini's regulatory and security credentials are genuinely strong. The NYDFS trust charter forces capital reserves and fiduciary duties. It was the first crypto exchange and custodian in the world to earn SOC 1 Type 2 and SOC 2 Type 2 certifications, renewed annually. Its core custody has never suffered a headline exchange hack of the kind that felled Mt. Gox or FTX. Customer crypto in custody is held in segregated cold storage.

On the critical side, Gemini's biggest failure was not a hack but a lending product. Gemini Earn let users earn yield by lending crypto to Genesis, a lender owned by Digital Currency Group. When Genesis halted withdrawals on 16 November 2022, roughly 900 million dollars of Gemini customer assets were frozen. Genesis filed for bankruptcy in January 2023. The SEC charged both Gemini and Genesis with offering unregistered securities; Genesis separately paid a 21 million dollar SEC penalty. New York's Attorney General sued, alleging investors were misled about Earn's risks, and in 2024 recovered about 50 million dollars for more than 230,000 investors.

The eventual outcome was better than many feared. Through the Genesis bankruptcy, distributions began in 2024, an initial roughly 97 percent in-kind payout as of the Settlement Effective Date of 9 May 2024, with the remainder to follow, and ultimately delivered a full in-kind recovery. Because crypto prices had climbed since the freeze, Gemini said Earn users received about 2.18 billion dollars of assets back in kind, which it framed as roughly a 232 percent recovery of the dollar value locked when Genesis paused withdrawals. In plain terms, a user who lent one bitcoin received one bitcoin back rather than its depressed 2022 dollar value. In January 2026 the SEC dismissed its lawsuit against Gemini over Earn, noting customers had been repaid in full.

Two smaller notes belong in the record: a 2022 incident in which a third-party vendor exposed Gemini customer email addresses and partial phone numbers, fueling phishing attempts, and the broader lesson that "regulated" reduces but does not remove counterparty and product risk.

How to get started (safely)

1. Confirm availability. Gemini serves the US and select markets; after its 2026 restructuring it exited the UK, EU and Australia, so check that your country is supported before signing up.
2. Create and verify your account. Expect full identity verification (KYC) with a government ID, since Gemini is a regulated entity.
3. Turn on strong 2FA. Use an authenticator app or a hardware security key, never SMS, and set up a withdrawal allowlist so funds can only leave to pre-approved addresses.
4. Fund with the cheapest rail. Link a bank account (ACH) rather than a card to avoid card processing fees.
5. Trade through ActiveTrader, not the simple app. This single choice can cut your fees by roughly an order of magnitude on larger orders.
6. Withdraw long-term holdings to self-custody. Move coins you are not actively trading to your own hardware wallet; an exchange balance is a claim on Gemini, not coins in your pocket.
7. Be skeptical of any yield product. If Gemini or anyone else offers "earn" style returns, understand exactly who is borrowing your assets and what happens if they fail. Earn's history is the cautionary tale.

Gemini vs alternatives

In plain terms: Coinbase is the larger, more liquid, more feature-rich US venue and usually the default for breadth. Kraken competes on low pro fees and deep spot and derivatives markets. Gemini differentiates on the trust charter, institutional custody and a transparent stablecoin, but it is the smallest of the three and carries the Earn history. None of them should be your permanent vault; a self-custody wallet is.

Risks and what to avoid

• Counterparty risk. Funds on any exchange are a claim, not bearer assets. Gemini is regulated, but regulation did not prevent the Earn freeze.
• Yield-product risk. Lending and "earn" programs add a hidden borrower who can default. Treat advertised yields as a signal to investigate, not a free lunch.
• Fee drag. The simple buy flow is quietly expensive. Using ActiveTrader is the difference between cheap and costly.
• Thin stablecoin liquidity. GUSD is transparent but small; do not assume deep markets or wide DeFi support.
• Business risk. Gemini is unprofitable, cutting costs and markets, and its shares have fallen far below the IPO price, drawing a shareholder lawsuit. That is survivable but worth tracking if you hold large balances there.
• Phishing. Given past data exposure, assume attackers know you use Gemini; verify every email and URL.

Safety checklist

• Enable app-based or hardware-key 2FA, never SMS.
• Turn on a withdrawal address allowlist.
• Use ActiveTrader to minimize fees.
• Keep only trading balances on the exchange; cold-store the rest.
• Read the monthly GUSD attestation before trusting large stablecoin balances.
• Avoid yield or lending products unless you fully understand the borrower.

Looking ahead

Gemini enters the back half of the 2020s as a smaller, leaner, publicly traded exchange betting that regulation is a durable moat rather than a cost center. The Earn saga is legally behind it, customers were repaid in full in-kind, and the Nasdaq listing plus the Calypso and credit-card businesses give it more than one revenue leg. But the market has been unforgiving: the stock has fallen sharply since its debut, losses remain heavy, and the company is cutting staff and retreating to the US. The open questions are whether it can reach profitability, whether GUSD ever grows beyond a niche, and whether its curated, compliance-first model can hold users who can find more assets and yield elsewhere. For a cautious US investor it remains a credible base camp, provided you keep long-term holdings in self-custody and treat any yield offer with suspicion.
