Kraken 與 Buenbit：比較這些加密貨幣交易所

When comparing Kraken vs Buenbit, investors are evaluating a global crypto exchange against a Latin American investing platform designed to help users protect and grow savings in volatile economies. Buenbit offers crypto, stocks and ETFs alongside yield products and OTC services, while Kraken provides a deeper exchange ecosystem with advanced trading tools, staking, derivatives and broader global reach. Below, we analyze how the two platforms compare across products, supported assets, fees, security and customer support to help you determine which fits your investment goals.

Kraken 於 2011 年在美國成立，是加密貨幣業界最早成立且最具規模的品牌之一。交易所於 Bitcoin 推出後不足兩年便正式成立，憑藉對安全、營運透明度及優質用戶體驗的高度重視，贏得全球認可。

目前，Kraken 為超過 190 個國家的逾 1,500 萬名客戶提供服務。Kraken 的產品由面向個人投資者的旗艦 Kraken 平台，以至透過 Kraken Pro 平台及 Kraken Desktop app 為進階及機構交易者提供的強大一站式交易平台，涵蓋多個範疇。

Kraken 的機構服務套件涵蓋現貨、槓桿、期貨市場、質押及場外交易，服務合資格客戶。Kraken 亦透過 Kraken 學習中心 大力投資教育，支援新手及經驗豐富的交易者。

Kraken 總部位於懷俄明州，並透過定期發布 Proof of Reserves 強調其對問責的承諾。這項做法早於 2014 年便由 Kraken 引入業界。Kraken 亦是首間在 Bloomberg Terminal 上市的加密貨幣交易所，有助於連繫傳統金融與數位資產。

憑藉在美國、加拿大、英國、歐盟等主要市場取得的監管牌照，以及協助處理 Mt. Gox 債權人申索等案件的經驗，Kraken 建立了穩定並符合規例的營運聲譽，成為尋求安全且持久的加密貨幣交易所人士信賴的平台。

Founded in 2018 by Federico Ogue, Buenbit is an Argentine investing platform acquired by Nexo in December 2025. The platform has processed more than $2 billion in volume and serves users primarily in Argentina and Peru, with plans for expansion into Mexico. Buenbit's core product is a mobile app that enables users to purchase over 500 stocks, cryptocurrencies and ETFs. The platform also offers yield-generating products on cryptocurrencies and stablecoins, an OTC desk for large-volume transactions, and support for USD deposits from services like Wise, Deel and PayPal. As a CNV-registered Virtual Asset Service Provider, Buenbit operates within Argentina's regulatory framework. Following the Nexo acquisition, Buenbit clients are gaining access to Nexo's broader suite of products, including crypto-backed loans, structured investment tools, futures trading and a loyalty program. The platform positions itself as a wealth-preservation tool for users in high-inflation markets.

Buenbit has earned trust in the Argentine market through its compliance-first approach and focus on savings protection. However, Kraken's global infrastructure and operational history since 2011 offer a fundamentally different level of exchange maturity. While Buenbit is transitioning under Nexo's ownership, Kraken has operated continuously and independently for over 14 years, building a security-first reputation reinforced by Proof of Reserves audits and internationally recognized certifications (ISO/IEC 27001, SOC 2 Type II). For investors who value long-term platform stability, global liquidity and a proven track record across multiple market cycles, Kraken provides a more established exchange environment.

Kraken 的生態系旨在支援各種交易風格及不同經驗程度的用戶。你可以透過簡潔易用的流動 app 隨時隨地進行交易，或使用 Kraken Pro 的進階工具，包括詳細圖表、自定義訂單類型及即時市場數據。

平台支援所有用戶進行現貨交易；符合資格的地區亦可進行槓桿交易（槓桿最高達 5 倍）及期貨合約（槓桿最高達 50 倍）。機構及高淨值客戶可以透過 Kraken 的場外交易櫃枱及 Kraken Prime 服務使用更多服務。

除交易外，Kraken 亦提供加密貨幣質押，涵蓋超過 21 種資產；獎勵最高可達 17% 年化收益率，實際數額視乎代幣及網絡狀況而定。你可以直接透過平台質押 以太坊（ETH）、Solana (SOL) 及 Cardano (ADA) 等資產，賺取被動收益。

Kraken 亦透過 Krak 支援全球數碼支付。這項功能讓你可以免交易手續費發送加密貨幣或現金。

2024 年，Kraken 推出建基於 Optimism 的 SuperChain 的 Ink Layer-2 網絡，為中心化交易所與熱門 DeFi 協議之間提供順暢的連接。

Buenbit provides a multi-asset investing experience through its mobile app, enabling users to buy and sell cryptocurrencies, stocks and ETFs from a single interface. The platform also offers yield-generating accounts on selected cryptocurrencies and stablecoins, with an OTC desk available for large-volume transactions. Following the Nexo acquisition, users are gaining access to additional products including crypto-backed credit, structured products like Dual Investment, advanced futures trading and the NEXO token loyalty program. Buenbit does not natively offer advanced exchange-style trading tools such as professional charting, multiple order types or high-frequency API access — its interface is oriented toward simplicity and accessibility.

Buenbit offers a practical multi-asset investing experience for users seeking wealth preservation in volatile markets, and the Nexo integration is expanding its product suite. However, its core interface remains oriented around simplicity rather than exchange-grade execution. Kraken delivers a more comprehensive crypto-native platform: Kraken Pro for professional trading, spot, margin and futures markets, staking on 21+ assets, recurring buys, asset bundles and institutional services via Kraken Prime and OTC. For investors who need advanced order execution, deeper liquidity and a fully developed trading and investing stack, Kraken provides a stronger overall environment.

客戶可在 Kraken 使用超過 600 種加密貨幣，包括 Bitcoin (BTC) 和 XRP (XRP) 等主要加密貨幣，以及各種山寨幣，從迷因幣到流動性質押代幣，一應俱全。

你亦可直接在 Kraken 應用程式交易超過 11,000 隻免佣金 ETF 及股票。合資格地區的客戶亦可投資xStocks，即這些股票的代幣化版本。
Kraken 支援以 10 種主要法定貨幣提款及充值，讓全球客戶可以快速便捷地為帳戶存入資金。

支援的法定貨幣包括：

• USD（美元）

• CAD（加拿大元）

• GBP（英鎊）

• EUR（歐元）

• JPY（日圓）

• AUD（澳元）

• CHF（瑞士法郎）

• ARS（阿根廷披索）

• MXN（墨西哥披索）

• BRL（巴西雷亞爾）

Kraken 亦支援 15 種穩定幣，包括 Tether (USDT)、USDC 及 USDG。

Buenbit offers access to over 500 stocks, cryptocurrencies and ETFs through its mobile app, providing a multi-asset portfolio experience. The platform supports fiat deposits in Argentine pesos and USD transfers via services like Wise, Deel and PayPal. Stablecoins such as USDT, USDC and DAI are available for savings and yield products. While the combined stock and crypto offering is broad for a regional platform, the specific depth of crypto listings may be more limited compared to large global exchanges focused exclusively on digital assets.

Buenbit's multi-asset model offers convenient portfolio diversification within one regional platform. However, Kraken's crypto-specific depth is significantly broader. With 500+ cryptocurrencies, 10 fiat currencies (including ARS), 15 stablecoins and access to 11,000+ stocks and ETFs in select regions, Kraken provides both wider digital asset coverage and comparable multi-asset capabilities. For investors who prioritize extensive crypto market access alongside traditional investment exposure, Kraken offers a more comprehensive and globally accessible portfolio experience.

Kraken 的交易量分級手續費模式分層清晰且透明，兼顧專業交易者及一般投資者的需要。

掛單手續費由 0.25% 起，吃單手續費為 0.40%；高交易量的個人及機構亦可享有折扣。訂閱 Kraken+ 後，合資格客戶在每月交易量達到指定上限前，更可完全免除這些手續費。

大部分加密貨幣及法定貨幣充值均可免費，惟部分充值方式及特定資產可能例外。Kraken 亦透過在交易確認前顯示所有手續費，進一步提升透明度，讓客戶事先清楚了解相關手續費，避免面對高昂的意外費用。

Buenbit's pricing structure includes spread-based fees on crypto and stock transactions, with specific costs varying by asset type and transaction method. Yield products and OTC services may carry their own fee considerations. Following the Nexo acquisition, the NEXO token loyalty program may introduce additional fee discount tiers for active users. Users comparing platforms should evaluate total execution costs including spreads, deposit fees and any subscription or loyalty requirements, particularly if they plan to trade frequently or in larger volumes.

Buenbit's evolving fee structure under the Nexo umbrella may introduce loyalty-based discounts, but comparing total costs against exchange-style pricing requires careful evaluation of spreads and additional charges. Kraken's maker-taker fee model is publicly documented with transparent volume tiers. No loyalty tokens or subscription tiers are required to access competitive rates, and withdrawal fees are fixed and clearly displayed. For traders who prioritize predictable, exchange-grade pricing without complexity, Kraken's model offers greater transparency and scalability.

Kraken 廣泛被視為業內最安全的加密貨幣平台之一。自成立以來，Kraken 從未發生導致客戶資金損失的保安事故，這是少數其他交易所能夠作出的保證。客戶可享有多層帳戶保障，包括使用密碼金鑰的雙重認證、PGP 電郵加密、設有範圍限制的細緻 API 金鑰權限、可設定的帳戶逾時、即時監察可疑活動、提幣白名單及主密鑰設定。

Kraken 於 2014 年率先推出儲備證明，並持續透過定期及可由獨立人士驗證的審計引領業界。這項加密程序讓客戶可以隨時親自查閱其帳戶餘額如何由真實資產作為支持。Kraken 亦持有 ISO/IEC 27001:2013 認證，符合 SOC 2 Type 2 審計要求，並營運一項穩健的公開漏洞獎勵計畫。

Buenbit is registered as a Virtual Asset Service Provider with Argentina's CNV (Comisión Nacional de Valores), operating within the country's regulatory framework for crypto services. The platform implements standard account-level security controls including two-factor authentication and KYC verification. Following the Nexo acquisition, Buenbit clients are gaining access to Nexo's broader security infrastructure, which includes cold storage practices and additional custody safeguards. However, the security model is in transition as the two platforms integrate, and users may want to monitor how operational practices evolve during this period.

Buenbit's CNV registration and the upcoming Nexo integration provide regulatory grounding and potentially enhanced custody. However, the integration period introduces transitional uncertainty that users should consider. Kraken's security model has been tested and refined over 14+ years with no reported client fund breaches. Its Proof of Reserves audits, ISO/IEC 27001 and SOC 2 Type II certifications, and layered defense architecture operate as an established, independently verifiable system. For investors who prioritize a mature, stable security framework with a long-standing track record, Kraken provides a higher level of operational assurance.

Kraken 以回應迅速且專業的客戶服務見稱，提供多個客服渠道以滿足不同用戶的需要。客戶可以使用真人客服提供的 24/7 線上客服、透過電郵提交請求，或在特定情況下直接致電與客服專員交談。

Kraken 的多語言客服團隊可以使用十多種語言為用戶提供協助，讓公司更有效地服務全球客戶群。

交易所亦在客戶滿意度方面獲得高度評價，並在 Customer Centricity World Series 中獲選為「最佳 AI 客戶體驗應用獎（歐洲）」得主。Kraken 專注於清晰度、同理心及解決問題的速度，持續令其客戶體驗在競爭激烈的市場中脫穎而出。

Buenbit provides customer support through its app and email channels, with an online help center for common questions. Following the Nexo acquisition, the platform's support infrastructure is expected to expand with Nexo's 24/7 personalized client care model. However, during the integration period, support structures and response times may vary as the two systems merge. Users requiring immediate, time-sensitive assistance should consider how the current support model compares with exchanges that already offer established, round-the-clock global support.

Buenbit's multi-asset model offers convenient portfolio diversification within one regional platform. However, Kraken's crypto-specific depth is significantly broader. With 500+ cryptocurrencies, 10 fiat currencies (including ARS), 15 stablecoins and access to 11,000+ stocks and ETFs in select regions, Kraken provides both wider digital asset coverage and comparable multi-asset capabilities. For investors who prioritize extensive crypto market access alongside traditional investment exposure, Kraken offers a more comprehensive and globally accessible portfolio experience.

Buenbit and Kraken both serve Argentine investors but with different positioning. Buenbit provides a multi-asset investing platform focused on savings protection in high-inflation markets, now bolstered by Nexo's global infrastructure following its December 2025 acquisition. Kraken operates as an established global exchange ecosystem with 500+ cryptocurrencies, advanced trading tools, staking, derivatives in eligible regions and transparent exchange-grade pricing. For investors who prioritize trading depth, global liquidity, an independently proven security track record and a stable, fully integrated platform, Kraken represents the more comprehensive and established option.
