Kraken vs KuCoin: Como estas bolsas de criptoativos se comparam

Choosing an exchange can shape your entire trading experience, from which assets you can access to how confident you feel about security, regulation, and support. With hundreds of platforms available, finding one that matches your comfort level is essential.

Kraken is a global brand with over a decade of experience and tens of millions of clients. Thanks to a variety of investment products and award-winning customer support, Kraken appeals to both beginner investors and expert traders.

KuCoin positions itself as a global exchange built for users who want access to a broad range of tokens, margin and futures trading, and automated trading tools.

However some users may prefer platforms with tighter regulatory alignment, simpler interfaces and higher customer service standards. This Kraken vs. KuCoin article will walk you through how the two crypto exchanges compare.

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 2017 by Michael Gan and Eric Don, KuCoin is a global cryptocurrency exchange that markets itself as “The People’s Exchange.” It has grown rapidly by focusing on broad asset availability and accessibility for retail traders worldwide.

KuCoin offers spot trading, margin trading, futures, staking, lending, trading bots, and various earn products across 1000+ cryptocurrency, including many small-cap and emerging tokens. The platform supports both beginner and advanced users, with features such as automated trading tools and passive income products that appeal to retail participants.

Indeed, KuCoin’s vast range of listed tokens has made it popular among traders seeking broader crypto exposure. Additionally, a user-friendly interface and low barriers to entry have resulted in strong adoption in emerging markets.

It should be noted that KuCoin’s offshore operations have resulted in regulatory scrutiny and enforcement action in certain jurisdictions, relating to its lack of proper registration. For users concerned with compliance, this may be a high-risk signal. Additionally, it is unavailable in the US and UK.

Traders consistently turn to Kraken for its focus on security, transparency and compliance—principles that have earned long-term trust from millions worldwide.

Where other exchanges emphasise breadth and experimentation, Kraken prioritizes stability, clear regulation and protection of client assets.

This disciplined approach has allowed it to build one of the industry’s strongest reputations for reliability and user confidence.

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.

KuCoin offers an extensive range of trading products designed for both retail and advanced users. Alongside spot markets, it supports margin and futures trading with various contract types, including USDT and coin-margined perpetuals. The platform also features crypto staking and lending, as well as savings tools for users seeking yield-generation opportunities.

KuCoin’s suite of automated trading bots enables users to deploy strategies such as grid and futures bots without coding experience. KuCoin provides API access for tech-savvy developers and users to automate their trading, access real-time market data, and integrate with third-party platforms. The API supports spot, margin, and futures trading, and users can create API keys to connect their applications securely.

KuCoin's Web3 wallet gives users control over their private keys and access to DeFi, NFTs, and other Web3 applications.

This broad product mix makes KuCoin appealing to active traders who want flexibility and access to emerging crypto opportunities.

While KuCoin provides a vast range of trading tools, including margin, futures, automated bots, staking, lending and early-access token listings, this breadth comes with more operational complexity and regulatory unknowns.

In comparison, Kraken, presents a more refined product ecosystem; a streamlined spot market, regulated futures, staking, and support for U.S. stocks and ETFs, all underpinned by clear governance and institutional-level infrastructure.

Traders who value advanced features and oversight will find Kraken’s balanced approach more suited to scalable, long-term use than KuCoin’s high-feature but higher-risk environment.

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.

KuCoin supports a notably wide spectrum of digital assets, positioning it as a platform favoured by users seeking broad token access and niche altcoins.

KuCoin lists over 1,000 cryptocurrencies across spot and futures markets, including BTC, ETH and SOL, plus a large number of lower-cap and recently launched coins. It offers more than 1,300 trading pairs, reflecting its asset-breadth and market variety.

KuCoin also supports 50 fiat currencies including USD, EUR, AUD, INR, ARS, PHP and more, alongside its fiat on-ramp services such as Simplex, Banxa and OTC gateways, as well as support for 12 different stablecoins including USDT and USDC.

Although KuCoin provides a broader selection of cryptocurrencies, Kraken’s curated listings and regulated approach give clients confidence that the assets they trade have been vetted for quality and compliance.

From leading tech stocks such as Tesla and Apple, to liquid staking tokens and memecoins, Kraken not only supports the most popular assets across TradFi and crypto, but also provides powerful tools for trading these assets all within a single streamlined platform. Investors can trade stocks and ETFs, explore the latest cryptocurrencies, stake assets or even send money globally at zero cost.

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.

KuCoin maintains a competitive fee structure aimed at rewarding active traders and KCS token holders. Standard spot trading fees begin at 0.10% for both makers and takers, with reductions available through higher trading volumes or by using KCS to pay fees.

Futures trading fees are typically around 0.02% for makers and 0.06% for takers, with additional discounts for VIP users. Deposits are generally free, while withdrawal fees vary based on the asset and network.

KuCoin’s approach prioritizes flexibility and tiered incentives, making it one of the lower-cost options among major global exchanges.

While KuCoin offers attractive discounts and rewards for active traders, Kraken appeals to users who value transparent, predictable pricing without complex token-based incentives.

Kraken’s flat and clearly published fee structure makes it easier for traders to understand their true costs, with no need to hold an exchange token or meet high-volume thresholds to access competitive rates.

Combined with its regulated operations and consistent operational quality, Kraken provides a straightforward, trust-driven exchange for users who prefer stable pricing over tiered or promotional fee models.

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.

KuCoin implements multiple security measures, including multi-factor authentication, withdrawal whitelists, and regular Proof of Reserves audits verified by third-party firm Hacken. These audits show KuCoin maintains collateral ratios above 100% across major assets, helping reassure users that funds are backed 1:1.

However, the exchange has previously faced scrutiny over its regulatory standing and exposure to compliance risks, particularly in the U.S. market. In September 2020, KuCoin suffered a major hack that resulted in the theft of approximately $280 million worth of cryptocurrencies from its hot wallets.

Kraken’s approach to security and custody goes far beyond just technical safeguards, it is a key part of the company’s brand.

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 KuCoin 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.

KuCoin advertises 24/7 customer service through its online help centre. However, user-feedback is mixed, reviews frequently cite delayed response times, opaque support communications and problems with account or withdrawal issues.

Some users do report positive experiences, but the overall sentiment highlights customer support as a relative weak point for the crypto exchange.

Although KuCoin provides a broader selection of cryptocurrencies, Kraken’s curated listings and regulated approach give clients confidence that the assets they trade have been vetted for quality and compliance.

From leading tech stocks such as Tesla and Apple, to liquid staking tokens and memecoins, Kraken not only supports the most popular assets across TradFi and crypto, but also provides powerful tools for trading these assets all within a single streamlined platform. Investors can trade stocks and ETFs, explore the latest cryptocurrencies, stake assets or even send money globally at zero cost.

Kraken and KuCoin both cater to active traders but differ sharply in philosophy and track record. KuCoin prioritizes asset variety and trading flexibility, offering a vast range of cryptocurrencies, margin and futures products, and automated trading tools that appeal to users seeking high market exposure.

Kraken takes a more measured approach, focusing on security, regulatory compliance, and transparency. Its predictable fee model and reputation for trust make it a preferred choice for users who value stability and oversight, as well as token choice and high quality investment products.

Kraken offers a comprehensive platform for both individuals and institutions, with over 500 digital assets available, advanced trading features, and 24/7 multilingual support, Kraken is built for clients who want transparency, choice and long-term reliability. Meanwhile, KuCoin focuses on digital asset range, automation and market exposure.
