Kraken vs Bitfinex: Como estas exchanges de cripto se comparam

Finding the right crypto exchange can be challenging with so many options available. Kraken and Bitfinex both provide platforms to trade digital assets, but they cater to different types of users.

Kraken, founded in 2011, is known for its strong security, transparent operations, and varied product offering suitable for beginners, active traders, and institutions. Bitfinex provides access to a limited number of digital assets and appeals to experienced investors rather than crypto newcomers.

This Kraken vs. Bitfinex article breaks down how the two crypto exchanges differ in key areas such as products, fees, asset support, security, and customer service.

Fundada em 2011 nos Estados Unidos, a Kraken está entre os nomes mais antigos e estabelecidos na indústria de criptomoedas. Lançada menos de dois anos após a estreia do Bitcoin, a exchange ganhou reconhecimento global pelo seu forte foco em segurança, transparência operacional e uma experiência de utilizador de alta qualidade.

Hoje, a Kraken serve mais de 15 milhões de clientes em mais de 190 países. As suas ofertas variam desde a plataforma principal Kraken para investidores individuais, até plataformas de negociação completas e poderosas para traders avançados e institucionais através da plataforma Kraken Pro e da aplicação Kraken Desktop.

A suite institucional da Kraken abrange mercados à vista (spot), de margem, de futuros, staking e negociação OTC para clientes qualificados. A Kraken também investe fortemente em educação através do Kraken Learn, apoiando traders novos e experientes.

Com sede em Wyoming, a Kraken destaca o seu compromisso com a responsabilidade através de Provas de Reservas regulares, uma prática que introduziu na indústria em 2014. Foi também a primeira crypto exchange a ser listada no Bloomberg Terminal, ajudando a preencher a lacuna entre as finanças tradicionais e os ativos digitais.

Com licenças regulatórias em mercados-chave, incluindo os EUA, Canadá, Reino Unido, UE e um histórico de assistência em casos como os pedidos de credores da Mt. Gox, a Kraken construiu uma reputação de operações estáveis e conformes, o que a torna um destino de confiança para quem procura uma crypto exchange segura e duradoura.

Founded in 2012 by Raphael Nicolle, Bitfinex is a long-standing cryptocurrency exchange catering primarily to professional and institutional traders. Operated by iFinex (the same company that owns stablecoin issuer Tether), it played a prominent role in early crypto market development and remains an influential platform today.

Bitfinex is known for its spot, margin and derivatives capabilities, as well as its deep liquidity on major crypto pairs. While it lists a much smaller range of assets than many of the more consumer-focused exchanges, its advanced order types, customizability and APIs clearly make it an attractive venue for its ~2m users. Bitfinex also operates an OTC desk for large trades, and delivers services such as lending and staking on select assets.

Bitfinex’s reputation can be attributed to its deep liquidity and sophisticated trading infrastructure (particularly for large-cap crypto assets). Given its lengthy track record, its margin funding and lending markets are some of the industry’s most established options. It continues to be a popular platform for advanced traders placing large orders.

However, the exchange is unavailable in major jurisdictions (the US, Canada and parts of Europe), and its proximity to Tether has previously attracted regulatory scrutiny. And while it delivers sophisticated tools for power users, its focus on advanced trading makes it less suitable for beginners and casual users.

When comparing platforms, users frequently lean toward Kraken because of its track record for regulatory compliance, transparency and institutional-grade security. Kraken serves tens of millions of clients, providing them access to products such as spot, margin, futures and tokenised equities, all under a unified, trusted ecosystem.

In contrast, Bitfinex has typically catered to more speculative users, with its deep liquidity and advanced derivatives, yet its history of regulatory scrutiny and security incidents increases perceived risk for users who prioritize long-term stability and oversight.

For traders who emphasise reliability, clear governance and a streamlined platform for both retail and institutional needs, Kraken’s long-established foundation often makes it the preferred choice.

O ecossistema de produtos da Kraken foi concebido para suportar uma vasta gama de estilos de negociação e níveis de experiência. Os utilizadores podem negociar em movimento com a sua aplicação móvel otimizada ou aceder a ferramentas mais avançadas através do Kraken Pro, que oferece gráficos detalhados, tipos de ordem personalizados e dados de mercado em tempo real.

A plataforma suporta a negociação spot para todos os utilizadores, com negociação de margem (até 5x de alavancagem) e contratos de futuros (até 50x de alavancagem) disponíveis em regiões elegíveis. Clientes institucionais e de elevado património líquido podem aceder a serviços adicionais através da mesa OTC da Kraken e da oferta Kraken Prime.

Além da negociação, a Kraken oferece staking de cripto em mais de 21 ativos, com recompensas até 17% APY dependendo da moeda e das condições da rede. Os utilizadores podem ganhar passivamente ao fazer staking de ativos como Ethereum (ETH), Solana (SOL) e Cardano (ADA) diretamente através da plataforma.

A Kraken também suporta pagamentos digitais globais através do Krak, uma funcionalidade que permite aos utilizadores enviar cripto ou dinheiro sem taxas de transação.

Em 2024, a Kraken lançou a sua rede Ink Layer-2, construída na SuperChain da Optimism, proporcionando uma ponte contínua entre exchanges centralizadas e protocolos DeFi populares.

Para aqueles que procuram aprofundar os seus conhecimentos financeiros, o Kraken Learn oferece recursos educacionais que abrangem desde os princípios básicos da blockchain até estratégias de negociação avançadas.

Bitfinex offers a comprehensive range of trading products designed for sophisticated market participants. The platform supports spot trading of more than 170 cryptocurrencies and 400+ trading pairs.

It also provides margin trading with up to 10x leverage via peer-to-peer funding, a derivatives market featuring perpetual swaps and futures, and a dedicated OTC desk for large-volume trades.

Beyond these, Bitfinex supports tokenised securities and ecosystem features aimed at bridging real-world assets and digital markets.

Kraken offers a broader, more extensive product set than Bitfinex. Beyond key spot, futures and margin trading, it also provides crypto staking, zero-fee global payments, and stock and ETF investing.

Kraken offers clients more tools, markets, and assets, all in one streamlined platform. This breadth and pace of innovation are why many clients pick Kraken over Bitfinex.

Os clientes podem aceder a mais de 600 criptomoedas na Kraken, incluindo as principais como Bitcoin (BTC) e XRP (XRP), bem como uma variedade de altcoins, desde memecoins até liquid staking tokens.

Existem também mais de 11.000 ETFs e ações sem comissão disponíveis para negociar diretamente na aplicação Kraken. E para clientes em locais elegíveis, podem investir em xStocks, que são versões tokenizadas destes ativos.
A Kraken suporta levantamentos e depósitos em dez principais moedas fiduciárias, tornando rápido e conveniente para os clientes globais financiarem as suas contas.

As moedas fiduciárias suportadas incluem:

• USD (Dólar dos EUA)

• CAD (Dólar Canadiano)

• GBP (Libra Esterlina)

• EUR (Euro)

• JPY (Iene Japonês)

• AUD (Dólar Australiano)

• CHF (Franco Suíço)

• ARS (Peso Argentino)

• MXN (Peso Mexicano)

• BRL (Real Brasileiro)

Existem também 15 stablecoins suportadas, incluindo Tether (USDT), USDC e USDG.

Bitfinex supports a limited selection of assets, listing just over 170 cryptocurrencies and more than 400 trading pairs.

The platform also supports five different fiat currencies and six leading stablecoins including USDC and DAI. Trading pairs span major coins such as BTC, ETH and USDT, along with some smaller-cap tokens, but Bitfinex’s selection is much more restricted compared to Kraken.

Bitfinex lists more than 170 assets, covering a balance of large-cap and mid-cap cryptocurrencies.

Kraken, however, offers a broader and more regulated selection of over 500 digital assets and 11,000+ traditional instruments via Kraken Securities. From leading tech stocks such as Tesla and Apple, to memecoins, this integration of digital and traditional markets allows Kraken users to diversify across popular asset classes while maintaining exposure to carefully vetted cryptocurrencies.

Bitfinex has recently added tokenized securities however they are only regulated in Kazakhstan and El Salvador offering limited exposure for global traders.

For traders who prioritize compliance, liquidity, and institutional oversight, Kraken’s curated listings offer a higher level of market trust than Bitfinex’s more selective approach.

O modelo de taxas da Kraken baseado no volume é escalonado e transparente para apoiar tanto traders profissionais quanto investidores ocasionais.

Com taxas de maker a começar em 0.25% e taxas de taker em 0.40%, existem também descontos disponíveis para indivíduos e instituições de alto volume. Com uma subscrição Kraken+, estas taxas podem ser totalmente eliminadas para clientes elegíveis até determinados volumes mensais.

A maioria dos depósitos de cripto e fiduciários são gratuitos, com algumas exceções dependendo do método de transação e do ativo específico. A Kraken também destaca a transparência ao exibir todas as taxas antes de uma transação ser confirmada, garantindo que os clientes estão cientes de todas as taxas antecipadamente e evitam surpresas dispendiosas.

Bitfinex employs a maker-taker fee model with pricing tiers tied to trading volume and native token holdings. For spot markets, makers begin at 0.10% and takers at 0.20%, with reductions available as 30-day trade volume increases.

On the derivatives side, maker fees may drop to 0.020% and taker fees to around 0.045%, again depending on volume and token-based discounts.

Cryptocurrency deposits are generally free on Bitfinex, while fiat deposit and withdrawal fees vary. For example, wire deposits are charged at 0.10% (with a minimum amount) and withdrawals via express bank wire can incur 1% fees.

Bitfinex offers volume-based discounts and token incentives for active traders, but Kraken sets itself apart through fee transparency and consistent pricing across its global markets.

Kraken’s clearly published maker-taker structure and absence of complex token dependencies make it easier for users of all experience levels to estimate actual trading costs.

For traders who prioritize stable, predictable fees within a regulated framework, Kraken delivers clarity over Bitfinex’s volume-tier model.

With Kraken’s consistent execution quality and its regulated operations, the platform offers a simple, trustworthy experience for users.

A Kraken é amplamente considerada uma das plataformas de cripto mais seguras do setor. Desde a sua criação, a Kraken nunca sofreu uma violação que resultasse na perda de fundos de clientes, uma afirmação que poucas outras exchanges podem fazer. Os clientes beneficiam de proteção de conta multicamadas, incluindo 2FA com chaves de acesso, encriptação de e-mail PGP, permissões de chave API granulares com limites de alcance, tempo limite de conta configurável, monitorização em tempo real para atividade suspeita, lista de permissões para levantamentos e definições de chave mestra.

A Kraken foi pioneira na Prova de Reservas em 2014 e continua a liderar o setor com auditorias regulares e independentemente verificáveis. Este procedimento criptográfico permite que os clientes revejam pessoalmente como os seus saldos de conta são apoiados por ativos reais, a qualquer momento. A Kraken também possui a certificação ISO/IEC 27001:2013, conformidade com a auditoria SOC 2 Type 2 e opera um robusto programa de recompensas por bugs público.

Bitfinex implements strong security controls including two-factor authentication, biometric login options, cold-storage wallets, and automated fraud/abuse monitoring systems.

The platform requires all users to enable 2FA on their accounts for logins, withdrawals, and API access. Bitfinex’s security features also include setting a custom withdrawal confirmation phrase, which serves a function similar to anti-phishing codes. And for the majority of its cryptocurrency holdings, Bitfinex uses a multi-layered system that incorporates cold storage.

Unfortunately, its security history is marked by a substantial hack in 2016 in which approximately 119,756 BTC were stolen, underscoring its past governance lapses and tainting its reputation.

Kraken’s approach to security goes beyond technical safeguards, it’s a core part of the company’s identity.

With a clean record of zero breaches since 2011, consistent Proof of Reserves audits, and adherence to strict regulatory standards, Kraken delivers institutional-grade protection for every user.

While Bitfinex offers extensive verification and transparency efforts, Kraken’s long-standing commitment to security continues to set it apart.

A Kraken é conhecida pelo seu serviço de apoio ao cliente profissional e responsivo, oferecendo vários canais de apoio para satisfazer as diferentes necessidades dos utilizadores. Os clientes podem aceder ao chat ao vivo 24 horas por dia, 7 dias por semana, com agentes humanos reais, enviar pedidos por e-mail ou (em casos selecionados) falar diretamente com um especialista de apoio por telefone.

A equipa de apoio multilingue da Kraken pode ajudar os utilizadores em mais de uma dúzia de idiomas. Isto ajuda a empresa a servir a sua base de clientes global de forma mais eficaz.

A exchange também obteve altas classificações na satisfação do cliente e foi reconhecida como Vencedora do Melhor Uso de IA em CX (Europa) na Customer Centricity World Series. O seu foco na clareza, empatia e rapidez na resolução de problemas continua a distinguir a experiência do cliente da Kraken num espaço competitivo.

Bitfinex provides customer support through its online help center and email ticketing system, with response times varying based on query volume.

The platform offers multilingual support documentation and a detailed knowledge base, covering account management, API integration, and trading guidance. However, unlike some competitors such as Kraken, Bitfinex does not currently provide live chat or phone-based assistance.

User feedback often highlights professional responses, but they are sometimes delayed causing customer frustration.

Bitfinex lists more than 170 assets, covering a balance of large-cap and mid-cap cryptocurrencies.

Kraken, however, offers a broader and more regulated selection of over 500 digital assets and 11,000+ traditional instruments via Kraken Securities. From leading tech stocks such as Tesla and Apple, to memecoins, this integration of digital and traditional markets allows Kraken users to diversify across popular asset classes while maintaining exposure to carefully vetted cryptocurrencies.

Bitfinex has recently added tokenized securities however they are only regulated in Kazakhstan and El Salvador offering limited exposure for global traders.

For traders who prioritize compliance, liquidity, and institutional oversight, Kraken’s curated listings offer a higher level of market trust than Bitfinex’s more selective approach.

Both Kraken and Bitfinex are established exchanges that cater to active traders and institutions, but they differ in priorities. Kraken emphasizes trust, transparency, and regulation, offering users a secure environment backed by independent Proof of Reserves audits and robust compliance standards.

Bitfinex appeals to professional traders comfortable operating in a more open, less regulated environment. However, its history of security breaches and regulatory scrutiny may concern users who prioritize long-term stability and oversight.

For users seeking a compliant and trusted venue with a growing range of traditional and digital assets, Kraken remains a preferred choice.

For most investors, from individuals to institutions, Kraken’s reputation for reliability, compliance, and client protection makes it the stronger all-around choice.
