This Kraken vs. Bullish comparison breaks down several common and crucial aspects to help you choose which platform is best suited to your goals.

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 2020 by Brendan Blumer, Bullish is a cryptocurrency exchange with a strong emphasis on regulatory compliance, transparency and institutional-grade market infrastructure. The platform caters to professional and institutional players over retail, offering its services in 50+ jurisdictions. As of 2025, it trades publicly on the New York Stock Exchange (NYSE:BLSH).

Bullish’s stack consists of spot, margin and derivatives trading, complete with modest levels of leverage. Its modern infrastructure is engineered to support high volume and API usage, making it particularly attractive to quantitative traders, market makers and institutions. Beyond its core offering, it also recently launched Bullish Social — a blockchain-based Web3 social platform.

Bullish’s well-rounded suite, high-throughput design and commitment to compliance separate it from some of its offshore competitors who operate with less regulatory clarity. As a professional venue, it also stands out against consumer-oriented platforms and legacy exchanges.

Bullish doesn’t target global accessibility, favoring jurisdictions with regulated markets over worldwide coverage. Additionally, it is much more restricted in both its asset support and its maximum leverage than retail-focused competitors.

These are not necessarily downsides for serious traders and institutional investors. However, consumers may be better served by competitors with familiar interfaces, better accessibility and broader asset listings.

As one of the longest standing cryptocurrency exchanges, Kraken’s reputation and consistency over the years have attracted a loyal and ever-growing clientbase. Founded in 2011 and headquartered in Wyoming, it has thrived in bull and bear markets alike, delivering a secure, trustworthy and innovative investment platform.

Kraken’s deep-rooted commitment to security and transparency still shines through today. With their powerful infrastructure combined with compliance-ready products, clients can trust that their funds and data are safe.

While Bullish specializes in institutional-grade trading, Kraken provides the best of both worlds — offering user-friendly solutions for entry-level investors, as well as advanced tools for high value traders.

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.

Bullish focuses on providing a regulated trading environment, with products aimed at high networth individuals and institutional clients. Its core offering is spot and margin trading with up to 3× leverage for eligible users, as well as perpetual and dated futures contracts on major cryptocurrencies like BTC, ETH and SOL with up to 7x leverage.

These derivatives are only offered in select jurisdictions to professional and institutional traders. Bullish also provides API access for algorithmic traders, alongside connectivity options designed to handle high-volume strategies.

Recently, Bullish has expanded its ecosystem through Bullish Social, a Web3 social platform where users can connect, share content, and interact with token-based features.

Kraken provides a wider, more comprehensive product set than Bullish. Beyond core spot and margin trading, it offers futures and margin trading, stock and ETF investing, zero-fee global payments, advanced staking and emerging services such as ICO access, AI-driven automation and access to proprietary funding.

On Kraken, clients have more markets, tools, and opportunities in a single platform. This breadth and pace of innovation are why many choose Kraken over Bullish.

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.

Bullish’s offering is limited with a little over 50 cryptocurrencies available, six stablecoins and two different fiat currencies with USD and EUR.

Many of the supported assets on Bullish are restricted by the specific regions’ legal requirements.

Kraken appeals to users who want access to hundreds of cryptocurrencies and thousands of commission-free ETFs, all from within the same streamlined platform.

From leading tech stocks such as Tesla and Apple, to DeFi tokens and memecoins, Kraken not only supports the most popular assets across TradFi and crypto, but also provides powerful tools for trading these assets.

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.

Bullish offers competitive maker and taker fees, charging no maker fees on spot markets, while taker fees start at 0.01% but vary depending on trading volume, market and location. For margin and derivatives, fees are volume-based and differ by product, with details published in Bullish’s fee schedule.

Fiat deposits and withdrawals are only supported in USD and EUR, and associated banking fees depend on the method used. Users should check the latest information, as costs vary by region and payment type.

While Bullish might appeal to high-value traders and institutions thanks to their competitive pricing, Kraken’s equally competitive volume-based fees is a model friendly to beginners and experts alike.

Clients also benefit from Kraken’s broad fiat support — including USD, EUR, GBP, JPY, and more — making deposits and withdrawals more flexible compared to Bullish’s limited USD and EUR coverage.

Additionally, Kraken reinvests its fees into core business areas such as the exchange’s award winning customer support, industry leading security and an expanding product set.

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.

Bullish emphasizes a regulatory-first approach, operating under the supervision of the Gibraltar Financial Services Commission. The platform employs a layered security model, including two-factor authentication (2FA), encryption of data in transit and at rest, as well as strict withdrawal controls.

User assets are primarily held in cold storage, with only a small portion kept in hot wallets for liquidity purposes. Bullish also integrates real-time risk monitoring and institutional-grade custody standards.

While it has not experienced any major security breaches since launch in 2021, Bullish does not currently publish Proof of Reserves. Instead, it relies on regulatory compliance and third-party audits to verify solvency and asset protection.

Kraken is recognized as one of the most secure exchanges in the world. The majority of assets are held in offline cold storage, supported by regular Proof of Reserves audits and over a decade-long history without major breaches.

While Bullish emphasizes regulatory compliance and institutional safeguards, Kraken’s long track record of security and transparency provides greater reassurance to retail and institutional clients.

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.

Bullish provides customer support through its Help Center, email and ticketing system. Clients can browse self-service articles or submit a request for assistance via the platform.

Unlike Kraken, Bullish does not currently offer live chat or phone support, and available language coverage is limited to English. Its support services are more limited in scope compared to leading competitors such as Kraken, who provide real-time assistance and multilingual support across a number of different communication channels.

Kraken appeals to users who want access to hundreds of cryptocurrencies and thousands of commission-free ETFs, all from within the same streamlined platform.

From leading tech stocks such as Tesla and Apple, to DeFi tokens and memecoins, Kraken not only supports the most popular assets across TradFi and crypto, but also provides powerful tools for trading these assets.

Kraken and Bullish both emphasize security and regulatory compliance, but they take different approaches. Bullish is a newer, institutionally focused exchange with tight spreads and low fees, but it has limited fiat support, a narrower range of assets and restricted customer service. Its design appeals to advanced traders who value regulated infrastructure and a streamlined experience.

By contrast, Kraken offers a more comprehensive platform for both individuals and institutions. With 500+ supported digital assets, advanced trading features, crypto staking, Proof of Reserves audits, and 24/7 multilingual support, Kraken is built for clients who want transparency, choice and long-term reliability.

Bullish may appeal to institutional participants seeking a regulated environment, but for most retail and professional traders, Kraken provides the broader, more versatile option.
