Bydfi is ideal if:

Great for automation fans – If you enjoy trading bots, copy trading, or demo accounts, BYDFi delivers robust tools to trade efficiently without constant manual oversight.
Suited to traders chasing leverage – With support for high-leverage strategies and user-friendly interfaces, it's a solid pick for aggressive traders seeking powerful instruments in an accessible format.
Ideal for global beginners and pros alike – Its intuitive design and broad feature set make it equally approachable for new users just starting and those looking for advanced trading options.

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.

Bydfi isn’t ideal if:

No staking or lending features – If you're seeking income through asset staking or crypto loans, BYDFi currently doesn’t offer these options.
Limited fiat withdrawal support – Converting crypto into local currency outside the platform can be inconvenient or unavailable directly within BYDFi.
Advanced tools might overwhelm newcomers – Beginners may find features like high-leverage derivatives and automated bots more complex than user-friendly.

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

BYDFi charges a flat maker and taker fee of 0.1% for all spot trades; while VIP tiers may offer reductions, there’s no native-token discount outlined as standard.

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

Perpetual contracts carry a maker fee of 0.02% and taker fee of 0.06%, and the funding fee is exchanged every eight hours depending on market sentiment (positive or negative)—paid by longs to shorts or vice versa.

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

For major perpetual pairs, typical bid-ask spreads hover around 0.06%, reflecting tight pricing in high-liquidity markets.

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

Fiat Deposits & Withdrawals

Users can deposit fiat via providers like Banxa, Transak, Coinify, and Mercuryo; fees and processing speeds vary by region, with no flat rate transparency but generally fast credited times.

Hidden Costs

There’s a small fee embedded in crypto-to-crypto conversions, and while no inactivity fees are standard, express KYC or other convenience services may involve additional charges.

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

Purchasing €500 of BTC would incur a spot fee (~0.1%) plus any spread embedded in the quote, and if you then withdraw on-chain, you’d pay the network-based withdrawal fee—combining all these into the total cost.

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

Offering a robust selection, BYDFi supports over 550–900 cryptocurrencies and 600–800+ trading pairs for spot markets; the top 20 by volume typically include BTC/USDT, ETH/USDT, XRP/USDT and other high-liquidity altcoin pairs.

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 delivers a versatile range of trading tools, including spot, perpetual derivatives (Coin-M & USDT-M), copy trading, automated bots (grid, martingale), DCA strategies, demo accounts, on-chain trading via MoonX, but currently lacks options, ETFs, staking, or lending.

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

Liquidity remains moderate compared to major exchanges—with mid-level 24-hour volume and modest order book depth for BTC/USDT and ETH/USDT—implying that traders may encounter slightly wider pricing gaps than on deeper venues.

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

BYDFi includes a comprehensive toolkit

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

Certain regions face limitations—derivatives or high-leverage tools may be unavailable in places like the United Kingdom or other restricted jurisdictions, reflecting regulatory constraints in those locales.

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

The platform shines with its innovative MoonX on-chain engine offering DeFi access to hundreds of thousands of token pairs, and provides flexible bot-driven strategies, yet it doesn’t currently offer launchpad/pool features or staking/earn products.

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

BYDFi is legally operated by BYDFi Blockchain Limited, founded in April 2020, and is headquartered in Singapore; it serves a global client base under that corporate structure.

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

The platform holds Money Services Business (MSB) registrations in both the United States (FinCEN) and Canada (FINTRAC), but lacks explicit VASP or MiCA licensing in Europe, though it remains active across EU states.

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

BYDFi uses its own custody with deep cold storage and multi-signature wallets, and transparently publishes proof-of-reserve data showing full backing plus buffer for assets like BTC, ETH, and USDT, along with a user protection fund of 800 BTC.

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

A protection fund equivalent to 800 BTC is maintained to safeguard users’ assets in case of emergency situations or platform distress.

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

There are no public records or reports of hacks, service suspensions, asset freezes, or regulatory fines associated with BYDFi to date, indicating a clean operational track record.

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 multi-layered risk safeguards such as Google Authenticator–based 2FA, withdrawal whitelist, anti-phishing systems, and granular API or sub-account permissions for additional user control.

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

BYDFi publishes regular proof-of-reserve disclosures and maintains segregated user funds, though it does not appear to offer publicly visible monthly audit reports, wallet explorers, or guaranteed service-level agreements (SLAs).

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

BYDFi allows fiat deposits through credit/debit cards, e-wallets, and bank transfers via partners like Transak, Coinify, Alchemy Pay, and Mercuryo; minimums vary by method, card and e-wallet deposits are typically nearly instant, while bank transfers may take 1–3 business days.

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)

BYDFi offers trading with no KYC initially, but requires KYC for fiat withdrawals and higher limits; unverified users have lower withdrawal caps, while verified accounts unlock substantially higher limits and access to promotions.

BigONE features two identity verification tiers

Withdrawals

Crypto withdrawals depend on verification level and risk-controls; limits escalate from modest (e.g., ~1.5 BTC/day) for unverified users to higher tiers for verified ones, and you can withdraw via supported networks like ERC20, BEP20, TRC20, with processing subject to blockchain conditions.

limits, speeds & networks

Customer Support

BYDFi offers 24/7 live chat and email support, with a comprehensive FAQ and Help Center for self-service; response times are generally fast, especially via live chat, and documentation covers most common user inquiries.

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 provides a multilingual interface, displays balances and fees in multiple currencies (EUR, USD), and adapts to local regulations in supported countries, though full regulatory compliance varies by jurisdiction.

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 BYDFi mobile app is regularly updated and widely reported as stable and responsive, with minimal crashes noted by users—reflecting consistent maintenance and enhancements over time.

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

Users describe BYDFi’s interface as intuitively unified—a single layout that handles both spot and futures trading seamlessly—making it accessible for beginners while offering sufficient power for advanced users, though explicit “Lite” vs. “Pro” toggles aren’t prominent.

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

BYDFi’s robust infrastructure and low-latency design ensure fast order execution even during surges, reducing slippage and delays common in highly volatile periods.

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 exchange offers a fully functional demo trading environment and a Q&A support hub, though comprehensive educational materials or guides in Spanish are limited or not prominently featured.

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

BYDFi maintains active official communities across Discord, Telegram, X, and Medium, and offers referral programs that reward users for onboarding others—building engagement through a global network.

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

Seamless integration with TradingView enables direct charting and trade execution inside the platform; plus, BYDFi connects with third-party tax tools like CoinLedger and Divly via API or CSV exports for streamlined financial tracking.

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

BYDFi suits traders who value low-latency order execution, demo environments, community engagement, and powerful interface features—all in a unified layout—making it ideal for users transitioning from beginner to more sophisticated strategies.

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.
