What changed since the last update: Bitfinex Derivatives moved from the Seychelles to El Salvador in January 2025 after receiving a DASP licence. The core Bitfinex exchange received its own DASP licence in El Salvador on 12 May 2026. Bitfinex has charged no trading fees since 17 Dec 2025. In January 2025, US prosecutors asked the court to return to Bitfinex the 94,643 BTC recovered from the 2016 hack.

About Bitfinex

Bitfinex launched in 2012 and is one of a handful of exchanges still standing from that era. It has never tried to be a retail on-ramp.

Bitfinex BTC/USD trading interface with chart and order form

The platform is built for active traders: margin trading backed by a peer-to-peer funding market, perpetual derivatives, an OTC desk and tokenised securities.

One thing to settle immediately – US persons are strictly prohibited from holding an account under the terms of service, and several other jurisdictions are excluded as "prohibited persons". If you're American, stop here.

The exchange is owned by iFinex Inc., which also owns Tether. Paolo Ardoino serves as Tether's CEO and Bitfinex's CTO.

The link cuts both ways: Bitfinex quotes some of the deepest USDt books anywhere, and a shock to Tether would land directly on the exchange that lists it. That's a genuine concentration risk, and it's priced into how most professional desks size their balances there.

Since 2023 the group has rebuilt its regulatory base in El Salvador, entity by entity. Bitfinex Securities took the country's first Digital Asset Service Provider licence in April 2023.

Bitfinex Derivatives followed in January 2025, leaving the Seychelles and requiring users to accept updated terms. The core exchange received its own DASP licence on 12 May 2026.

All three arms now operate under Salvadoran authorisation.

Fees and Costs

Bitfinex went to zero on 17 December 2025. Maker and taker fees on spot, margin and derivatives are all 0.00%, with no volume tier and no token-holding requirement.

The same applies to tokenised securities and OTC trades. The old schedule – 0.1%/0.2% on spot, 0.02%/0.065% on derivatives – is gone, and the official fee page now simply reads "Zero".

Among large venues, nobody else matches this.

Zero trading fees does not mean zero cost. The costs that remain are worth more attention than the headline:

Zero fees – so who pays?

Bitfinex earns from four other sources: the 15% commission lenders pay on margin-funding interest; LEO token economics (buybacks funded from that revenue); spreads on large OTC and sizing services; and its stake in Tether via parent company iFinex. The trading screen is free; the ecosystem is not – but none of those sources touch your order's execution price.

Margin-funding commission. Lenders in the funding market pay 15% of the interest they earn.

Hidden offers cost 18%. Holding LEO cuts up to 5% off that rate.

If you lend rather than borrow, this is your real fee.

Position takeover. When Bitfinex assumes a position instead of liquidating it, it charges 5% of the loss you avoided.

Everything around the trade. Withdrawal fees, fiat deposit fees and perpetual funding rates are unchanged.

On a leveraged book held for days, funding will dwarf anything the old commission schedule ever cost you.

So who pays? Revenue now comes from the funding market, LEO's economics, OTC and securities flow, and the broader iFinex business.

For a high-turnover trader the arithmetic is unambiguous in Bitfinex's favour – but understand that your costs have moved from a published schedule to variable funding rates, which are harder to forecast.

Products and Features

Spot, margin up to 10x, and perpetual derivatives through Bitfinex Derivatives cover the core. Around 160 assets are listed – broad enough for major and mid-cap pairs, well short of the long tail on Binance or MEXC.

Beyond trading there's staking, Bitfinex Borrow for borrowing against BTC, tokenised securities via Bitfinex Securities, and a paper-trading environment that's genuinely useful for testing API strategies before committing capital.

The peer-to-peer funding market is the real differentiator. Rather than borrowing from the exchange at a fixed rate, you borrow from other users at rates set by supply and demand, choosing your own duration.

Lenders can earn meaningful yield on idle USD or USDt. No other exchange of this size runs margin this way, and traders who learn it rarely leave.

Positioning against the obvious alternatives: Kraken offers better regulatory standing and fiat rails but charges normal fees and caps leverage lower. Binance lists far more assets and has deeper altcoin books.

Deribit remains the venue for serious options. Bitfinex wins on BTC/USD depth, funding-market flexibility and, now, cost.

The interface assumes you already know what you're doing – advanced order types, dense charting, no hand-holding. The API is well documented and stable, which is why algorithmic traders have stayed through everything else.

Security and Regulation

The 2016 breach is the first thing most traders think of. 119,756 BTC were stolen. Bitfinex socialised the loss across all customers and issued BFX recovery tokens, then redeemed every one of them at full value within eight months – nobody was left out of pocket.

In January 2025 US prosecutors moved to return 94,643 recovered bitcoins to the exchange as restitution in kind; the remainder sits in a more complex claims process. Since then we found no reports of a breach or loss of customer funds at Bitfinex through 2024–2026, which is a longer clean run than several better-regulated competitors can claim.

On the regulatory side, the footprint is Salvadoran. CNAD has licensed more than 70 digital asset service providers – a real regime with real requirements, but not equivalent to SEC, FCA or EU MiCA supervision.

We found no MiCA authorisation. Bitfinex and Tether also settled with US authorities in earlier years over statements about Tether's reserves.

Treat El Salvador as a jurisdiction that permits the business, not one that will recover your funds if something goes wrong.

Verdict

88/100. Zero fees across spot, margin and derivatives, the deepest BTC/USD books in the industry, a funding market nobody else replicates, and nine clean years since the breach that defined its reputation.

For an experienced non-US trader who understands the counterparty trade-off, it's a strong venue – arguably the cheapest serious one available right now.

The reservations are structural, not operational. Licensing comes from El Salvador rather than a major financial centre.

The iFinex-Tether relationship concentrates risk in ways most exchanges don't. The 2016 breach still shapes how some traders see it, even though every affected customer was repaid.

And the platform offers nothing to someone learning.

Right for: professional and high-volume traders, funding-market lenders, BTC-focused desks. Wrong for: beginners, US residents, and anyone who wants EU- or UK-grade investor protection behind their balance.
