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.

Kuna is ideal if:

Effortless Quick Buys – If you prefer rapid purchases without account creation, Kuna’s “5-click” system lets you buy Bitcoin, Ethereum, or Tether in around 30 seconds directly to your wallet.
Straightforward and Friendly UI – Kuna offers a clean, intuitive interface (web and mobile) that’s especially suitable for newcomers and those who value simplicity and smooth navigation.
Regional Fiat Flexibility – If you're in supported areas, Kuna enables seamless fiat-to-crypto trades using local methods in UAH, USD, or RUB, plus tools like cash codes—making funding your trades frictionless.

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.

Kuna isn’t ideal if:

Limited Asset Variety – If you're looking to trade a wide range of cryptocurrencies or exotic altcoins, Kuna offers only a modest selection that may feel restrictive.
Basic Trading Tools Only – For those seeking advanced charting, technical indicators, or professional-grade trading features, Kuna’s platform remains quite simplistic.
No PayPal or Wallet Options – If you prefer funding your account with PayPal, Skrill, or Neteller, or need live chat or phone support, you’ll find those options aren’t available here.

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.

Kuna applies a flat 0.25 % trading fee for both makers and takers, without tiered volumes—though holding at least 100 KUN tokens grants VIP status, which waives maker fees entirely.

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.

Kuna does not offer futures or other derivative trading instruments; therefore, there are no associated maker, taker, or funding fees.

Average Spreads on Liquid Pairs

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

Kuna does not publicly disclose spread data, and their simplified fee model suggests minimal hidden spread, though precise average figures for these pairs are not available.

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.

Fiat deposits are accepted (e.g., via credit card for Ukrainian-issued Visa/Mastercard or via methods like Perfect Money, Payeer, Advanced Cash, or Kuna Code), with variable fees depending on the method—withdrawals mirror those deposit options, again with method-dependent fees and typical processing within short timeframes.

On-chain Withdrawals

Fixed vs Dynamic Network Fees

Crypto withdrawal fees are based on asset and network; for example, withdrawing BTC incurs a fixed fee of approximately 0.0005 BTC. Other assets like ETH or TRX may have different dynamic fees, though Kuna doesn’t specify those publicly across all networks.

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.

There’s no explicit information about inactivity fees or express KYC charges; however, currency conversion may incur a flat percent fee embedded in the exchange rate, depending on your selected method.

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.

Buying €500 worth of BTC would incur the standard 0.25 % trading fee and any minor spread embedded by the platform, plus the fixed withdrawal cost of ~0.0005 BTC when sending the funds on-chain—exact totals depend on BTC’s live price at the time.

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.

Kuna lists approximately 22 to 40 cryptocurrencies and supports around 40 trading pairs, with the most active ones being BTC/UAH, ETH/BTC, ZEC/UAH, DAI/UAH, ZEC/USDT, KUN/USDT, BTC/USDC, and ETH/UAH.

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.

Kuna’s product suite is straightforward—spot trading only (crypto–crypto and crypto–fiat), no margin, derivatives, ETFs, lending, copy trading, grid bots, automatic DCA, or options; however, it does offer staking rewards through holding certain assets.

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.

Kuna’s 24-hour volume is modest (several million USD equivalent), with BTC/USDT and ETH markets showing some activity; however, order-book depth is not publicly detailed, suggesting liquidity is appropriate for medium-sized trades but not high-frequency institutional-level operations.

Tools

BYDFi includes a comprehensive toolkit

Kuna supports basic order types like limit, market, and stop orders, features standard trading charts (not TradingView-native), and provides API access; it doesn’t offer advanced charting tools, OCO orders, price alerts, or built-in TradingView integration.

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.

While spot trading is broadly available, Kuna does not provide derivatives or advanced products in any region, and its services are restricted for U.S. users; features like staking may also be limited depending on local regulations.

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.

Kuna’s innovation footprint includes unique tools like Kuna Code (transfer via code), Kuna Pay (payment processing), and browser extensions from the community, but it currently lacks features such as a launchpad, launchpool, or differentiated flexible vs locked earning programs.

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.

Kuna was founded in 2014 in Ukraine and maintained operations through regional entities—including those in the UK and Lithuania—but as of March 2025, the platform has fully ceased operations and is no longer active.

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.

Kuna did not hold formal VASP licenses under European frameworks like MiCA, nor did it register under equivalent regimes; current regulatory programs such as those in the Cayman Islands or EU never applied to Kuna due to its closure prior to implementation of those licensing regimes.

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.

Kuna undertook what it called “the largest Proof of Reserves in history” to demonstrate backing of user funds, though there is no evidence of third-party audits, formal PoR implementation, or specified cold storage reserve ratios.

Insurance & Protection Funds

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

No formal insurance products or customer protection funds were publicly offered or advertised by Kuna at any point during its operation.

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.

Kuna maintained a calm incident history, with no publicly documented hacks, platform outages, account freezes, or regulatory fines reported prior to its closure.

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.

Kuna offered basic security features such as two-factor authentication (2FA) and email confirmations, though advanced tools like withdrawal whitelists, anti-phishing measures, tiered sub-accounting, or granular API permission controls were not prominently supported.

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).

There were no monthly transparency reports, public audit statements, or disclosed service-level agreements. While the platform shared its initiative around reserves, ongoing financial transparency metrics or operational dashboards were not made available.

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.

Fiat deposit options on Kuna include credit cards (limited to Ukrainian-issued Visa/MasterCard) and payment services like Advanced Cash, Perfect Money, Payeer, or Kuna Code; there’s no publicly stated minimum or maximum, and processing times vary—card payments can be nearly instant, while some transfer methods may take several minutes to days depending on method and region.

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.

Kuna requires identity verification to unlock full functionality—basic account creation has limited access, and submitting documents (ID, proof of address) elevates you to a fully verified level, with no public breakdown of tiered access or trading limits, but verification is mandatory for fiat operations.

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.

Cryptocurrency withdrawals on Kuna support networks like ERC-20, TRC-20, BTC (native), and others; BTC withdrawals, for example, incur a 0.0005 BTC fee and typically process within 10 minutes after email and 2FA confirmation—limits are set internally and not publicly disclosed.

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.

Kuna offers multilingual support via the help center and ticketing system (English, Ukrainian, Russian), with an extensive FAQ and tutorial base—while there’s no 24/7 live chat, support is accessible through email or tickets, and response times are generally prompt but unspecified.

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.

The platform supports English (as well as Ukrainian and Russian), displays prices and fees in common fiat currencies like €/USD, and reflects some local regulatory positioning (e.g., awareness of Lithuanian VASP licensing), although it remains primarily headquartered in Ukraine.

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.

Kuna offers a mobile app for both iOS and Android that integrates core features like deposits and withdrawals; while there’s no public data on crash rates or update frequency, documentation includes instructions for confirming withdrawals via the app—suggesting a maintained and functional experience.

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.

Kuna’s design is widely praised for being intuitive and accessible to beginners, with no separate “Lite” or “Pro” modes—just a unified interface that blends simplicity with functionality to help new traders start quickly while still serving seasoned users.

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.

Users report that orders on Kuna process nearly instantly under normal conditions; while data on crashes during volatile markets or extended KYC backlogs is limited, the lightweight design and responsiveness suggest generally stable performance even under pressure.

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.

Kuna currently offers limited educational materials and lacks demo or simulator tools; content is primarily in English, Ukrainian, and Russian, with no dedicated academy or learning hub in Spanish available at this time.

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.

Kuna fosters an active user community via its official Telegram and social media channels, alongside a generous affiliate/referral program (up to ~75% commission), though it doesn’t operate its own dedicated forums or Discord server.

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.

The platform doesn’t natively integrate with TradingView or third-party trading bots; there are no built-in tax reporting or accounting tools, making it more suited to straightforward trading rather than advanced automation or reporting workflows.

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.

Kuna shines for casual traders, especially in Eastern Europe, who want a no-frills, easy-to-navigate platform for basic spot trading in fiat and crypto—making it a solid fit for those seeking simplicity and regional accessibility rather than advanced trading features.
