Bitflyer is ideal if:

Great for cautious starters – Offers a clean, beginner-friendly interface with strong regulation and security, especially suited if you value peace of mind and a guided experience.
Smart for professionals too – Its Lightning platform and API support advanced trading styles while remaining within a trusted, compliant ecosystem.
Best for mainstream assets – Focuses on the core major cryptocurrencies rather than obscure altcoins—ideal if you're after simplicity, not a sprawling asset list.

Bigone is ideal if:

Strong security foundations — BigONE deploys cold wallet reserves, multi-signature storage, and enforced two-factor authentication, making it a solid pick if asset protection is your priority.
Flexible services ecosystem — Offers margin and futures trading, copy trading, staking, lending, and liquidity mining—all within a single platform, ideal for users who want diverse earning and trading options.
Beginner-friendly features — With demo accounts, low minimum deposits, an intuitive interface, and mobile access, it provides a gentle entry point for new traders keen to learn hands-on.

Bitflyer isn’t ideal if:

Not for altcoin hunters — Offers only a small selection of mainstream cryptocurrencies, limiting your options if you're looking to explore lesser-known tokens.
Limited advanced trading tools — Lacks robust derivatives, futures, lending, and staking features that active or margin traders often need.
Less competitive for cost-focused users — May involve higher spreads or fewer deposit options compared to more versatile, low-cost exchanges.

Bigone isn’t ideal if:

Not fully regulated transparency — The exchange doesn’t clearly disclose its regulation structure or provide detailed company background, which could raise trust concerns for users seeking fully licensed platforms.
Fiat limitations affect access — Lacks direct fiat deposit support in many regions and doesn’t allow bank/card funding in most cases, making it inconvenient for users who prefer traditional payment methods.
Security breach history — Recently suffered a significant hack targeting its hot wallet, temporarily halting trading and deposit services—which may deter those prioritizing operational resilience.

Fees & Total Costs

Spot Maker/Take

On bitFlyer’s Lightning Spot, maker and taker fees decrease progressively as your 30-day trading volume grows—from about 0.10 % at lower volumes down to roughly 0.03 % for very high turnover, with potential bespoke discounts for particularly active users or sizeable trades.

BigONE charges a flat 0.2 % for both maker and taker orders on spot trading, and applies discounts through its tiered VIP system—higher levels (Bronze to Challenger) qualify for lower maker/taker fees based on privilege points earned via volume, referrals, or holdings, with fees notably reduced at top tiers

Futures/Derivatives

bitFlyer offers Bitcoin futures and crypto CFDs with margin, where trading fees fall in the same low double-digit-basis-point range, plus a funding cost applied at fixed intervals based on price divergence from spot—creating a small rollover cost for open positions.

For perpetual futures contracts, BigONE charges 0.02 % maker and 0.06 % taker fees, with funding rate payments exchanged between long and short positions at regular intervals and no additional platform fee for funding itself

Average Spreads on Liquid Pairs

Spread information isn’t explicitly disclosed on bitFlyer, but based on its exchange design, liquid pairs typically carry modest spreads that are embedded in prices, especially via the Easy Exchange interface where the buy/sell price includes conversion margin rather than a separate fee.

While BigONE-specific spread data is scarce, the exchange’s BTC/USDT and ETH/USDT pairs are generally expected to align with tight spreads seen across highly liquid platforms—typically well below 0.1 % for such major pairs

Hidden Costs

There are no apparent idle-account or express-KYC charges; however, minor implicit costs can stem from currency conversion spreads if you’re using a non-native fiat, and any third-party wire or bank fees—which vary regionally—can affect your overall cost.

Implicit costs can include exchange rate conversion within OTC trades, inactivity charges (none publicly indicated), expedited KYC processes (not clearly associated with extra cost), or fallback spreads embedded in peer-to-peer OTC fiat conversions—so while not labeled as fees, these can quietly affect overall costs.

Real-World Cost Example: “€500 BTC

Buying €500 worth of BTC would entail a small embedded spread (via Easy Exchange) or low Lightning fee, plus the flat withdrawal charge (e.g., ~0.0004 BTC) if you choose to withdraw—resulting in a modest overall impact relative to the value but with no hidden or percentage-based surprises.

Suppose you convert €500 via OTC into USDT or BTC (with a typical provider fee of ~2 %), then place a spot trade paying ~0.2 % spot fee and accept a spread of ~0.05 %; if you then withdraw BTC on-chain (0.0005 BTC fee), your total cost would roughly include

Crypto Offering & Trading Features

Number of Coins & Pairs

bitFlyer supports around 7–8 core cryptocurrencies with roughly 10–12 trading pairs, mainly focused on major assets like BTC, ETH, LTC, BCH, ETC, LSK, MONA, and a few fiat pairings—its offering remains intentionally compact.

BigONE supports over 500 cryptocurrencies across more than 170 trading pairs, with its top-20 by volume typically including heavyweights like BTC/USDT, ETH/USDT, XRP/USDT, and SOL/USDT.

Product Range

The platform offers spot trading, margin trading (up to around 2×–4× leverage depending on region), Bitcoin futures (derivatives), Ethereum staking (upcoming), and OTC for large volume trades—but lacks more exotic features like options, ETFs, lending, copy-trading, automated bots, or full DCA tools.

You’ll find a broad suite of offerings—spot, margin trading (up to 10×), perpetual futures (up to 100× leverage), structured products (like dual investment), lending, staking, liquidity-mining, copy-trading, grid-bots, and DCA-style automated tools.

Liquidity

bitFlyer handles daily trading volumes in the low-hundreds of millions USD (with top pairs like BTC/JPY and ETH/JPY dominating), while its order book depth on main pairs remains modest compared with major global exchanges—sufficient for moderate trades but not for ultra-large orders.

The 24-hour trading volume is in the high hundreds of millions of dollars, and for key pairs like BTC and ETH, order book depth is robust enough to ensure smooth execution on sizable trades.

Tools

Advanced users benefit from a Lightning platform offering standard order types (limit, stop), custom alerts, charting, API and WebSocket access, and a native professional interface—but there’s no built-in TradingView integration or OCO orders.

BigONE supports a full range of order types—including limit, stop, TP/SL, OCO, post-only and reduce-only—along with trading alerts, advanced charting (TradingView integration), and both REST API and WebSocket access for automating or building strategies.

Geographic Restrictions by Product

Derivatives and margin capabilities vary by region, with limited pairs available in the U.S. (e.g., BTC/USD, ETH/USD, BCH/BTC) and broader altcoin access in Europe and Japan, reflecting regulatory constraints across jurisdictions.

Some advanced products—especially derivatives—are not accessible in restricted regions such as the United States and China, limiting access based on user location.

Innovation

Recent enhancements include ETH staking (pending launch) and ongoing CFD asset expansions. However, bitFlyer does not currently offer launchpads, flexible vs locked Earn products, or structured innovative financial instruments.

The platform includes innovative features like flexible versus fixed staking options, launchpad/launchpool alternatives, and other evolving income opportunities to help users engage with new projects or yield mechanisms.

Security, Regulation & Custody

Operating Entity & Jurisdiction

bitFlyer, Inc. was founded in 2014 and is based in Tokyo, Japan; it has extended operations internationally through regulated subsidiaries such as bitFlyer Europe to serve multiple regions globally.

BigONE is operated by One Trading Limited, founded in 2017 and registered in Seychelles; it also operates under the regulated entity BigONE Eurasia based in Astana International Financial Centre (AIFC), which is governed by the Astana Financial Services Authority.

Licenses/Registration

It holds Virtual Asset Exchange licensing under Japan’s FSA, and its European arm is a fully regulated payment institution in Luxembourg, holds the first VASP registration there, and undergoes annual audits by a Big Four firm.

The AIFC-based segment of BigONE holds licenses for operating as an investment exchange, clearing house, trading facility, and custodian—indicating formal oversight in that jurisdiction, though global licensing appears limited.

Custody

Customer assets are stored offline in proprietary cold wallets (often over 80–100%), with multilayer physical security; while specific Proof of Reserves disclosure isn’t public, financial statements undergo external audit and assets are held separately from company funds.

BigONE maintains a mixed custody model with segregated cold and hot wallets, employs multi-signature safeguards, and claims 100 % asset reserves with a mechanism enabling users to track reserves—though external audit or formal Proof of Reserves verification remains unpublished.

Insurance & Protection Funds

There’s coverage for unauthorized withdrawal via encrypted authentication and secure wallet infrastructure, but no widely advertised comprehensive insurance fund for hacks or exchange-level failures.

The platform holds an internal insurance reserve pool which it drew upon to fully compensate users after a security breach, acting as a form of self-insured protection.

Incident History

Apart from regulatory enforcement fines (e.g., levied by New York DFS), bitFlyer does not have public records of hacks or fund losses, reflecting a clean operational history with no major security breaches or customer fund suspensions.

In July 2025, BigONE endured a supply-chain attack targeting its hot wallet, resulting in a $27 million loss—private keys remained intact, the threat was contained, and full user compensation was made from internal reserves.

Risk Controls

The platform enforces strong password policies, two-factor authentication, account lockouts, encryption, and segregates client and company funds; features such as whitelists, sub-accounts, anti-phishing, and granular API permissions enhance security.

Security measures include mandatory two-factor authentication, real-time wallet monitoring, cold-hot wallet separation with multi-signature use, encrypted key management, and a public bug bounty program to surface vulnerabilities.

Transparency

While bitFlyer doesn’t publish monthly reserve reports or wallet addresses, it provides audited compliance, segregated custodian practices, encryption standards transparency, and maintains clear regulatory and operational SLAs via its regional legal frameworks.

While BigONE communicates openly during incidents and allows reserve tracking, it currently does not publish regular reports, maintain a public wallet address, or offer formal service-level agreements.

Deposits, Withdrawals, KYC & Support

Fiat Deposit Methods

Bank transfers (like SEPA, ACH, Fedwire) are available (sometimes free), with PayPal accepted in Europe; credit/debit card options depend on region, and deposit limits lift with full Trade Pro verification, while processing ranges from instant (cards) to 1–3 business days (bank transfers).

BigONE doesn’t support traditional fiat deposits directly through bank transfer, card, or e-wallets; instead, users rely on its OTC desk, where they can use channels like Alipay or WeChat Pay to convert fiat to crypto for trading. No official minimums or maximums are advertised, and timings depend on third-party provider processing.

Supported Fiat Currencies & Conversion

KYC (Verification Levels)

Accounts start at a basic (Standby) level with entry-only access, upgrade to Trade Class to deposit and trade within limits, and finally Trade Pro unlocks unrestricted activity—requiring progressively more ID documentation during verification.

BigONE features two identity verification tiers

Withdrawals

Crypto withdrawals have fixed minimums (e.g., 0.001 BTC plus fee), fiat withdrawals via bank take about 1–3 business days, and supported networks include the standard ones like BTC and ETH—no TRC20/BEP20 options mentioned.

limits, speeds & networks

Customer Support

Support is accessible via email and contact form (weekdays during business hours), with response typically within that timeframe; a FAQ/help center exists, but there’s no live 24/7 chat available.

The exchange offers 24/7 multilingual assistance via live chat and ticketing/email, though it lacks a direct call center; users can also consult an extensive FAQ and support library through the help center for self-service.

Languages & Localization

The platform offers native-level English (and other EU languages like French); pricing and fees are shown in local fiat (€/USD/JPY), with region-specific regulatory compliance embedded per locale.

BigONE’s interface supports over a dozen languages, including English, and displays trading figures in widely used currencies such as USD and EUR, but local regulatory nuances aren’t highlighted or tailored for specific jurisdictions.

App Quality & Stability

The mobile app supports core functions, is generally stable, though users report some limitations in advanced trading features, occasional minor bugs, and mixed ratings—recent updates aim to improve usability and reliability.

The BigONE mobile app—available on iOS and Android—is reported to be stable and smooth, with fast loading times, no significant lags or crashes noted, frequent updates, and a responsive UI that supports real-time trading and charting.

Experience, Performance & Ecosystem

UX/UI

bitFlyer strikes a balance between accessibility and power—casual users will find the Lite interface intuitive with a gentle learning curve, while experienced traders can switch to a Pro mode that offers deeper functionality without overwhelming novice users.

BigONE delivers a clean and intuitive interface that’s approachable for newcomers yet robust for advanced users; mobile and web platforms provide streamlined default views for quick trades and a more advanced layout (pro-style) for detailed charting and order control.

Performance

Order execution is generally responsive during normal conditions, but like many exchanges, there can be brief latency or slight slowdown during high-volatility spikes; KYC queues may also lengthen during strong bull runs, potentially delaying onboarding.

Order execution is generally fast and consistent, with minimal delays under normal conditions; even during high-volatility spikes, the system scales reliably, and KYC processing experience remains responsive without long queue delays—even in peak bull markets.

Education

The bitFlyer Academy provides beginner-friendly articles and guides to help users understand crypto fundamentals, though there’s no live demo or simulator, and educational content in languages other than English is limited.

The platform offers educational resources like a learning center and trading guides, though a full demo or simulator isn’t currently available; Spanish content is moderate—translated basic materials exist but in-depth tutorials are primarily in English.

Community

bitFlyer maintains an official help center and blog for updates, but lacks public community forums like Discord or Telegram; it does offer a referral program to incentivize bringing new users—but no broad peer-to-peer community space is currently provided.

BigONE nurtures an active community with official channels on Telegram and Discord, maintains a robust referral rewards program offering fee discounts, and engages users through social updates rather than formal forums.

Integrations

The platform supports API and WebSocket access for automated trading, yet does not offer native TradingView charts, external bot marketplaces, or integrated tax/accounting tools—so users typically rely on external systems for advanced analytics or bookkeeping.

There’s a built-in TradingView terminal for advanced technical analysis, supports integration with external trading bots via API, though it doesn’t offer native tax or accounting tools; users typically export data for external bookkeeping.

Who Each One Is Best For

bitFlyer is ideal for traders who want a secure, regulated platform with a choice between streamlined and professional UIs, while those who prefer community-driven tools, extensive integrations, or a learning sandbox may find more options on other platforms.

This platform suits a wide range—from beginner users who value simplicity and educational support to intermediate traders who want tools like grid bots and copy-trading, but power users seeking full tax or accounting automation may need complementary tools.
