Zero maker and taker fees. The first exchange with Lightning Network. A 2016 hack that scarred its reputation. And the Tether connection that still raises questions.
Bitfinex is one of the oldest cryptocurrency exchanges still operating. Founded in 2012 by iFinex Inc., it has survived a catastrophic hack, regulatory investigations, and years of controversy around its relationship with Tether. Most exchanges with that kind of history would be dead. Bitfinex is still here, still liquid, and still attracting professional traders.
In December 2025, Bitfinex made a bold move: permanently eliminating all maker and taker trading fees across every market. Zero fees on spot, margin, derivatives, OTC, and tokenized securities. No volume requirements. No token holding conditions. That makes Bitfinex the cheapest major exchange in the world for trading, undercutting Kraken at 0.26% and Coinbase at 0.40% by charging nothing at all.
But there is a reason we are not giving this a 9 out of 10. The 2016 hack cost users 119,755 BTC. The Tether relationship creates a conflict of interest that no other major exchange carries. Bitfinex does not serve US customers. And the regulatory profile is thinner than competitors with MiCA compliance or SEC registration. This is a powerful platform with real baggage. Here is the full picture.

On August 2, 2016, hackers exploited a vulnerability in Bitfinex's multi-signature wallet system, which was set up in partnership with BitGo. They stole 119,755 BTC, worth roughly $72 million at the time. Every customer account took a generalized haircut of approximately 36%. It was the second-largest exchange hack in Bitcoin's history at that point, behind only Mt. Gox.
What happened next is what separates Bitfinex from the exchanges that simply collapsed. Bitfinex issued BFX tokens to affected users, with each token representing one US dollar of losses. Within eight months, every single BFX token was redeemed at full face value. Users could take cash or convert their tokens into equity shares in iFinex, the parent company. All BFX tokens were subsequently destroyed.
In February 2022, US authorities recovered approximately $3.6 billion worth of the stolen Bitcoin and arrested Ilya Lichtenstein and Heather Morgan. However, the recovery raised its own controversy: Bitfinex considers its customers "whole" based on the dollar value at the time of the hack, not the appreciated value of the recovered coins. Users who held 1 BTC and received $600 in BFX token redemption watched that same Bitcoin climb past $100,000. The math is uncomfortable.
The bottom line: Bitfinex did repay users in dollar terms, which is more than Mt. Gox or FTX managed on their own. But the hack happened because of a fundamental security architecture failure. The question is whether the rebuild since 2016 is enough to justify trusting the platform again.
Bitfinex and Tether (USDT) share the same parent company: iFinex Inc. This is not a rumor or speculation. It is a disclosed corporate fact. Paolo Ardoino serves as CEO of both Tether and Bitfinex. The same leadership team runs both entities.
Why does this matter? In 2019, the New York Attorney General filed a case against iFinex, alleging that Tether had lent $850 million to Bitfinex to cover losses from a Panamanian payment processor called Crypto Capital. The allegation was that Bitfinex used Tether reserves, money supposedly backing USDT 1:1 with dollars, to plug its own financial hole without telling anyone.
In February 2021, Bitfinex and Tether settled with the NYAG for $18.5 million without admitting wrongdoing. The settlement required Tether to publish quarterly reserve attestation reports. Tether has published these reports through independent accounting firms since then.
Here is the honest take: the Tether connection is a genuine risk factor. If Tether ever faces a serious crisis of confidence, Bitfinex would be directly affected. No other major exchange carries this kind of corporate entanglement with a stablecoin issuer. You need to understand this risk before depositing significant funds. For most Bitcoin buyers, exchanges without this baggage ( Kraken, Coinbase) are safer choices from a counterparty risk perspective.
Zero. Since December 17, 2025, Bitfinex has permanently eliminated all maker and taker trading fees. This is not a promotional period. There are no volume requirements, no token holdings needed, and no account tier restrictions. Every user gets zero-fee trading from day one.
This applies across all markets: spot trading, margin trading, perpetual contracts, tokenized securities, and OTC. It is the most aggressive fee structure in the industry. Where Bitfinex still charges fees is on deposits and withdrawals:
| Action | Fee | Notes |
|---|---|---|
| Spot Trading (Maker) | 0% | Permanent, all pairs |
| Spot Trading (Taker) | 0% | Permanent, all pairs |
| Margin Trading | 0% | P2P funding rate still applies |
| Fiat Deposit (Wire) | 0.1% | Minimum fee applies |
| Fiat Withdrawal (Wire) | 0.1% | Minimum fee applies |
| Crypto Deposit | Free | Network fees paid by sender |
| BTC On-Chain Withdrawal | Dynamic | Based on network congestion |
| BTC Lightning Withdrawal | Near-zero | Routing fee only, typically under $0.01 |
The implications of zero trading fees are significant for active traders. A trader executing $10,000 in daily volume saves around $9.50 per day compared to Kraken Pro at 0.095% average. Over a year that is roughly $3,500. For high-frequency or algorithmic traders, the savings scale further. The catch is that you are accepting Bitfinex's regulatory and counterparty risks in exchange for those zero fees.
With zero trading fees since December 2025, Bitfinex wins on cost against every major exchange. Here is how the full picture compares, including deposit methods, security records, and availability:
| Exchange | Taker Fee | Maker Fee | Lightning | US Access | Hack Record |
|---|---|---|---|---|---|
| Bitfinex | 0% | 0% | ✓ Yes | ✗ No | 2016 ($72M) |
| Kraken Pro | 0.26% | 0.16% | ✓ Yes | ✓ Yes | Never |
| Coinbase Adv. Trade | 0.40% | 0.25% | App only | ✓ Yes | 2021 phishing |
| Binance | 0.10% | 0.10% | ✗ No | ✗ No (US only .us) | 2019 ($40M) |
Bitfinex wins on fees by a wide margin. But the fee advantage comes with a clear tradeoff: the 2016 hack history, the Tether connection, and the lack of US access. For traders who have weighed those risks and accepted them, zero fees is a compelling reason to trade here. For beginners or those prioritizing safety and regulation, the fee savings do not justify the additional risk.

Yes. And not just as an afterthought. Bitfinex was the first major exchange in the world to integrate the Lightning Network, adding support before any other comparable platform. That early commitment translated into real infrastructure: Bitfinex operates some of the largest Lightning nodes globally, with substantial channel capacity to support high-value transactions.
Both deposits and withdrawals work over Lightning. You can send Bitcoin from your self-custodial Lightning wallet directly to Bitfinex, or withdraw from Bitfinex to a Lightning wallet in seconds for near-zero cost. The maximum per Lightning transaction is 0.5 BTC, with payment channels supporting up to 2 BTC.
One useful feature: Bitfinex lets you convert between regular BTC and LN-BTC on the platform without paying a fee and without needing to open or manage a payment channel yourself. If you need to prepare Bitcoin for a Lightning withdrawal, the conversion is instant and free.
For context on why this matters: on-chain Bitcoin withdrawals can cost $1 to $20+ depending on mempool congestion. A Lightning withdrawal for the same amount costs a fraction of a cent in routing fees. For users who regularly move smaller amounts between exchange and mobile wallet, the savings accumulate quickly. Bitfinex's Lightning infrastructure is genuinely one of the best in the industry.
Bitfinex is built for traders who know what they are doing. The interface is dense, customizable, and packed with tools that go well beyond what casual buyers need. Here is what sets it apart:
Hidden orders, iceberg orders, scaled orders (split across a price range), trailing stops, fill-or-kill, immediate-or-cancel, One-Cancels-Other (OCO), and algorithmic routing. Most exchanges offer 4 to 6 order types. Bitfinex offers more than a dozen.
Integrated TradingView charting with over 100 technical indicators, drawing tools, and multi-timeframe analysis. The same charting engine used by professional trading desks worldwide.
Practice with real-time market data and virtual funds. Uses a separate balance so there is zero risk to actual holdings. Supports all order types including margin simulation.
Full REST and WebSocket APIs for algorithmic trading. Customizable API key permissions let you create read-only keys, withdrawal-only keys, or trading-only keys with specific IP allowlists.
Create sub-accounts within your main account for portfolio separation, team trading, or strategy isolation. Each sub-account can have its own API keys and funding.
For large trades (typically $100,000 and above) that would move the public order book, Bitfinex's OTC desk provides private liquidity at negotiated prices.
The interface is not beginner-friendly. That is by design. Bitfinex targets traders who already understand order books, margin mechanics, and position management. If you are new to Bitcoin, start with Kraken or Coinbase first, then consider Bitfinex once you have the fundamentals down. Jumping into Bitfinex with no trading experience and using margin is a reliable way to lose money quickly.
Bitfinex uses a peer-to-peer margin funding model, which is different from how most exchanges handle leverage. Instead of Bitfinex acting as the lender, its users lend to each other through an open marketplace.
For borrowers (margin traders): You can take on up to 10x leverage on supported pairs including BTC/USD. You post collateral, borrow funds from the lending pool, and pay a floating interest rate set by the market. Positions are liquidated if your collateral falls below the maintenance margin. With zero trading fees since December 2025, the only ongoing cost of a margin position is the funding rate you pay to lenders.
For lenders: You deposit USD, BTC, or other supported assets into the funding marketplace and set your minimum acceptable rate and duration. When a borrower accepts your terms, your funds go to work earning daily interest. Rates fluctuate with market demand. During high-volatility periods when leveraged traders are active, lending rates can spike significantly. This is a passive income mechanism that does not require you to trade.
The lending feature is one of the most distinctive aspects of Bitfinex. For users with significant idle stablecoin or Bitcoin holdings, lending on Bitfinex can generate returns. But understand the risk: your funds are on exchange while lending, not in self-custody. Given Bitfinex's history, that counterparty risk is real. Only lend what you can afford to have frozen or delayed in a worst-case scenario.
A note on leverage: margin trading with 10x leverage means a 10% adverse price move wipes out your entire position. Bitcoin can move 10% in a single hour. Treat margin trading as a tool for experienced traders with clear risk management, not a way to amplify returns for beginners.
After the 2016 hack, Bitfinex rebuilt its security infrastructure significantly. Here is the current setup:
| Security Feature | Details |
|---|---|
| Cold Storage | 99.5% of user assets in offline multi-signature wallets |
| Two-Factor Authentication | Mandatory on all accounts. Supports Google Authenticator, hardware keys (YubiKey) |
| Withdrawal Address Whitelisting | Only pre-approved addresses can receive withdrawals |
| Time-Delayed Withdrawals | New withdrawal addresses require a waiting period before first use |
| Manual Review for Large Amounts | Large withdrawals are manually reviewed before processing |
| IP Tracking and Login Monitoring | Real-time alerts for new login locations, with instant account freeze option |
| PGP Email Encryption | Communications can be PGP-signed and encrypted |
| Third-Party Security Audits | Regular audits by external cybersecurity firms |
| Bug Bounty Program | Researchers paid to find and disclose vulnerabilities |
| DDoS Protection | Infrastructure-level protection against denial-of-service attacks |
The 99.5% cold storage figure is industry-leading. Most exchanges keep 95 to 98% cold. The combination of address whitelisting, time-delays, and manual review for large withdrawals creates multiple checkpoints before funds can leave the platform. These are the right controls.
What is missing compared to peers like Kraken: Bitfinex does not publish proof of reserves. Kraken runs quarterly Merkle tree audits that users can cryptographically verify. Bitfinex has not implemented equivalent transparency. That gap matters for sophisticated users who want to verify their funds exist without trusting Bitfinex's word. It is a notable omission given the platform's history.
Bitfinex operates under iFinex Inc., which is incorporated in the British Virgin Islands. It adheres to standard KYC and AML protocols, requiring identity verification for account access. However, Bitfinex's regulatory profile is thinner than exchanges that have pursued major regulatory licenses in their primary markets.
The platform explicitly does not serve US residents, having exited that market following the 2021 NYAG settlement. This is not a soft restriction. Bitfinex actively blocks US IP addresses and verifies residency during KYC.
Bitfinex Securities, its tokenized assets arm, holds regulated status in two jurisdictions: the Astana International Financial Centre (AIFC) in Kazakhstan, regulated by the Astana Financial Services Authority (AFSA), and El Salvador under the Comision Nacional de Activos Digitales. Bitfinex Securities received an increased platform capacity from AFSA in late 2025, expanding to $310 million total capacity.
For the main exchange, Bitfinex is described by independent analysts as having a "moderate regulation and safety profile" compared to competitors. Kraken holds FCA registration in the UK and is MiCA-compliant in the EU. Coinbase is SEC-registered and NASDAQ-listed. Bitfinex operates without equivalent regulatory anchoring in major Western jurisdictions. For users who prioritize regulatory protection, this is a meaningful difference.
The honest bottom line on regulation: Bitfinex is a legitimate operating exchange with real compliance infrastructure, not a fly-by-night operation. But it operates with less regulatory oversight than its top-tier competitors. You get less protection if something goes wrong, and no recourse through Western financial regulators.
Bitfinex is not for everyone. But for the right kind of trader outside the US, it is a powerful platform. Here is the honest breakdown:
Bitfinex is a paradox. It offers the best trading fees in the industry (literally zero), the deepest Lightning Network integration of any major exchange, and a professional toolkit that rivals dedicated trading platforms. At the same time, it carries the most baggage of any exchange on this list: the 2016 hack, the Tether conflict of interest, the NYAG settlement, and a regulatory profile thinner than its top competitors.
The fees alone would justify a much higher score. Zero trading fees permanently, with no strings attached, is genuinely remarkable. That is why the trading tools category scores 10. But an exchange that lost 119,755 BTC in a security breach less than a decade ago, that shares its parent company with the most controversial stablecoin in crypto, and that settled a regulatory case involving misrepresented reserve disclosures cannot score 9 out of 10 on trust. The baggage is real.
Compare this to Kraken at 8.5: never hacked, MiCA-compliant, proof of reserves, slightly higher fees. For most Bitcoin buyers outside the US, Kraken is the better choice because security and regulatory standing matter more than the fee difference. But for experienced traders who have priced in those risks and want maximum tools at zero cost, Bitfinex makes sense.
How to use Bitfinex correctly: Complete KYC verification. Enable 2FA with a hardware key if possible. Whitelist withdrawal addresses. Never leave more Bitcoin on the platform than you need for active trading. Withdraw to a hardware wallet regularly. Treat Bitfinex as a trading venue, not a storage solution. That approach captures the fee advantage while limiting your exposure to exchange risk.

Bitfinex has made significant security improvements since the 2016 breach. The exchange now stores 99.5% of user assets in offline, multi-signature cold storage. It mandates two-factor authentication on all accounts, supports hardware security keys like YubiKey, and conducts regular third-party security audits. Withdrawal protections include address whitelisting, time-delayed processing for new addresses, and manual review for large amounts. The 2016 hack was a serious failure, but the infrastructure rebuild since then has been substantial. No repeat incident has occurred in the decade since.
Yes. Since December 17, 2025, Bitfinex has permanently eliminated all maker and taker trading fees across spot, margin, derivatives, securities, and OTC markets. This is not a promotional offer. There are no volume requirements, no token holding conditions, and no account tier restrictions. Other fees still apply: fiat deposits by wire incur 0.1% (with a minimum), fiat withdrawals are 0.1%, and crypto withdrawals carry dynamic network fees. But the actual trading itself costs nothing.
Bitfinex stopped serving US customers after regulatory pressure and a 2021 settlement with the New York Attorney General. The NYAG investigation found that Bitfinex had used Tether reserves to cover $850 million in losses and failed to disclose this to users. Bitfinex paid $18.5 million to settle without admitting wrongdoing, and chose not to pursue the extensive federal and state licenses required to operate legally in the US. American residents cannot create accounts or trade on the platform.
On August 2, 2016, hackers exploited a vulnerability in Bitfinex's multi-signature security setup with BitGo, stealing 119,755 BTC (worth roughly $72 million at the time). Bitfinex issued BFX tokens to affected users, with each token representing one dollar of losses. All accounts took a generalized 36% haircut. Within eight months, Bitfinex redeemed all BFX tokens at full face value, either in cash or as equity shares in parent company iFinex. In February 2022, US authorities recovered approximately $3.6 billion worth of the stolen Bitcoin and arrested two suspects.
Bitfinex and Tether (USDT) share the same parent company, iFinex Inc. This relationship has drawn heavy scrutiny. The NYAG investigation revealed that Tether lent $850 million to Bitfinex to cover losses from a payment processor called Crypto Capital. Critics argue this creates a conflict of interest where the largest stablecoin issuer is financially intertwined with an exchange. Supporters note that Tether has since published regular attestation reports and that the loan was repaid. The connection is a legitimate concern for risk-conscious users.
Yes. Bitfinex was the first major exchange to integrate Lightning Network, supporting both deposits and withdrawals. Lightning transactions settle in seconds with near-zero routing fees. The platform operates some of the largest Lightning Network nodes globally. Maximum Lightning payment capacity has expanded over time to 0.5 BTC per transaction, with payment channels supporting up to 2 BTC. Bitfinex also offers free on-platform conversion between standard BTC and LN-BTC without opening a payment channel.
Bitfinex offers peer-to-peer margin funding with leverage up to 10x on supported trading pairs. Instead of Bitfinex lending you money directly, other users fund your margin positions through the platform's lending marketplace. Borrowers pay interest rates set by market supply and demand. Lenders earn passive income on idle assets. This P2P model creates competitive rates and gives lenders a way to generate yield without trading. Margin trading carries significant risk: liquidation can wipe out your position if the market moves against you.
Bitfinex supports a wide range of order types built for professional traders. Beyond standard market and limit orders, you get stop-limit orders, trailing stops, fill-or-kill, immediate-or-cancel, scaled orders (spread across a price range), hidden orders (invisible on the order book), iceberg orders (partial visibility), and algorithmic order routing. The platform also offers One-Cancels-Other (OCO) orders for bracketed trading. This is one of the deepest order-type selections on any exchange.
Yes. Bitfinex offers a Paper Trading feature that lets you simulate trades using real-time market data with virtual funds. Paper Trading uses a separate account balance so there is no risk to your actual holdings. It supports the same order types and interface as live trading. This is useful for testing strategies, learning the platform, or experimenting with margin positions before committing real capital.
Both are veteran exchanges targeting experienced traders, but they differ in important ways. Bitfinex now charges zero trading fees, while Kraken Pro charges 0.26% taker and 0.16% maker. Both support Lightning Network deposits and withdrawals. Kraken has a 14-year hack-free record, while Bitfinex suffered the 2016 breach. Kraken serves US customers and offers proof of reserves; Bitfinex does not serve the US and has the Tether relationship as a trust concern. Kraken is the safer, more regulated option. Bitfinex wins on fees and advanced trading tools.
Bitfinex Securities is a regulated platform for tokenized real-world assets (RWAs) operated as a separate entity. It is regulated by the Astana Financial Services Authority in Kazakhstan and the Comision Nacional de Activos Digitales in El Salvador. The platform facilitates tokenized bond and equity offerings. Total assets on Bitfinex Securities grew to $250 million in 2025, with platform capacity expanded to $310 million. This is a separate product from the main exchange and targets institutional capital markets rather than retail traders.
No. Do not store significant amounts of Bitcoin on any exchange long-term, and this applies doubly to Bitfinex given its history. The 2016 hack resulted in a 36% haircut on all customer balances. Even with improved security since then, exchange custody means you do not control your private keys. Buy on Bitfinex if the zero fees and liquidity suit your needs, then withdraw to a hardware wallet like a Trezor, Ledger, or Coldcard. Self-custody removes exchange risk entirely.
