Probit is ideal if:

Great for exploring diverse assets If you value access to a broad selection of cryptocurrencies—especially niche altcoins—ProBit Global offers one of the widest catalogs available.
Perfect for privacy-minded traders With optional KYC and no compulsory identity checks for standard usage, it suits users who prefer trading with minimal personal data.
Solid for passive income seekers Integrated staking options and opportunities to participate in IEOs make ProBit attractive for investors looking to earn without active day trading.

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.

Probit isn’t ideal if:

Not for advanced margin traders Limited functionality for leveraging or derivatives may frustrate experienced users seeking more complex strategies.
Not ideal for fiat-heavy users If you prefer depositing or withdrawing traditional currencies directly, ProBit relies on third-party gateways and doesn’t natively support fiat operations.
Not beginner-friendly The interface and limited real-time support options—like no live chat—can make it challenging for newcomers navigating the platform solo.

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

ProBit Global charges a flat 0.2% for both maker and taker spot trades by default, but if you stake PROB (the native token), you’ll qualify for VIP levels and can reduce fees significantly—even down to around 0.05% or lower when paying with PROB, depending on your tier.

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

ProBit Global currently does not offer futures or derivatives trading, so there are no associated maker, taker, or funding fees to consider.

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

While ProBit doesn’t publicly publish exact spread figures, the BTC/USDT pair on major platforms typically shows mid-market spreads of a few dollars or a very small fraction of a percent; ProBit’s liquid pairs likely fall within that tight range, especially for well-traded assets.

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

Fiat deposits are handled via third-party gateways (like Simplex, MoonPay, Mercuryo), each with varying fees typically ranging from ~1–5%; speed depends on the provider—often near instant or up to a few business days—while ProBit does not support fiat withdrawals, only crypto withdrawals.

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

Withdrawal fees vary by blockchain and adjust dynamically based on network congestion; they are typically network-level fees—deducted in the asset you’re withdrawing—and fluctuate rather than being fixed values.

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 are generally no inactivity penalties; hidden costs may include currency conversion spreads when funding via non-USD/EUR gateways, and expedited KYC or premium services may incur extra fees through payment partners, not from ProBit directly.

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

If you convert €500 via a payment gateway, expect ~3–5% fee plus a small spread, then trade into BTC with roughly a 0.2% trading fee, and finally withdraw crypto with a small dynamic network fee—altogether, total costs could range around ~4–6% of the original amount, depending on variables.

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

ProBit Global features a vast catalog—around 800+ cryptocurrencies across 1,000+ spot markets, with the top-20 by volume including major pairs like BTC/USDT and ETH/USDT, alongside other highly traded 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

It offers spot trading, staking/earn programs, grid trading bots, automated DCA tools via third-party bots (e.g., Cryptohopper, DeltaBadger), and token launchpads, but does not support margin, futures/perpetuals, options, crypto ETFs, loans, or copy trading.

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

ProBit Global maintains solid liquidity with daily trading volumes typically ranging in the hundreds of millions USD, and order book depth on BTC/USDT and ETH/USDT is sufficient for smooth execution, especially for mid-sized orders.

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

The platform supports limit, market, IOC, and FOK order types, integrated grid and algorithmic trading via visual bots, offers API/WebSocket access, and customizable trading interfaces—but it doesn’t have native TradingView charting.

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

Some products like staking events or launchpad access may be limited in certain countries, and derivatives are universally unavailable—some services might even be restricted where KYC isn’t supported.

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

ProBit continues to innovate with an active launchpad program (hosting hundreds of token sales), and staking/earn offerings that may include flexible vs locked options, helping users participate in new token listings and earn passive rewards.

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

ProBit Global is a privately held cryptocurrency exchange, founded in 2017, operating under a corporate entity based in the Seychelles, with additional registered points of contact in European hubs to support compliance and local operations.

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 exchange does not hold formal VASP or MiCA licenses and operates outside of comprehensive regulated frameworks, relying instead on regional registrations and voluntary compliance where practicable.

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

ProBit Global secures around 95% of user assets in offline cold wallets, combined with encryption and multi-factor authentication; however, it does not publish proof of reserves or formal audit reports.

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

There is currently no custodian insurance or dedicated protection fund backing user assets, meaning funds are not covered in the event of a breach or other loss.

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

Incident History

ProBit maintains a clean track record—no hacks, breaches, floods, or regulatory fines have been reported since its founding—highlighting a strong security reputation to date.

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

Users benefit from comprehensive security controls, including support for 2FA (with hardware keys like FIDO U2F), passkeys, biometric authentication, anti-phishing safeguards, and granular API permissions; there are also options for account whitelisting and layered access controls.

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

Although there are no public monthly reserve or audit reports nor on-chain wallet disclosures, the platform does offer a bug bounty program and maintains stable infrastructure uptime, but does not publish SLAs or external transparency metrics.

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

ProBit Global allows fiat purchases via credit/debit card and bank transfer through third-party providers, with buys typically processed within minutes to a few hours depending on provider; minimums and maximums vary by provider and region, and exact values are defined by the payment gateways rather than ProBit itself.

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)

There are two KYC tiers: Step 1 (email only) allows basic deposits, trading, and withdrawals up to about $5,000 daily; Step 2 (identity verification) unlocks full platform access, staking, IEO participation, and higher withdrawal ceilings (up to $500,000 with 2FA enabled for at least 7 days).

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 have defined minimum amounts and dynamic network fees; supported networks include major blockchains like ERC-20, TRC-20, and BEP-20—withdrawals are generally processed promptly, subject to blockchain confirmation times.

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

ProBit offers customer support primarily via email and a ticketing system, with response times generally within a few hours to a day; it also maintains a well-structured FAQ and help center to guide users through common queries.

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 is localized in over 40 languages, including English, and displays pricing in major fiat terms like USD or EUR; local payment methods vary by region, and relevant fees are shown at the point of transaction.

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 mobile app is described as stable and user-friendly across devices, with regular updates enhancing features and performance; while exact crash rate data isn’t publicly stated, user feedback suggests a smooth and reliable experience.

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

The platform offers a clean, intuitive interface with a short learning curve; the mobile app even includes a lighter version (“ProBit Global Lite”) optimized for simplicity, while the standard web and mobile versions offer more control and customization for experienced users.

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

ProBit Global delivers fast order execution with minimal latency and reliable uptime, even during volatile market spikes; however, identity verification (KYC) may take longer during high-traffic periods, especially around major crypto bull runs.

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

While ProBit has a help center and support articles, it lacks built-in simulator or demo trading tools; educational content in Spanish or other languages tends to focus on FAQs rather than structured courses or videos.

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

ProBit maintains active community channels including Discord and Telegram, as well as a referral program that rewards users for bringing in others—creating a collaborative and engaged user community.

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

The platform integrates directly with TradingView charts and supports third-party trading bots like Cryptohopper or WunderTrading; tax or accounting tools aren’t built-in but users can export data to manage finances externally.

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

ProBit suits privacy-conscious traders who value wide crypto choice and automated bot support, while beginners and those expecting advanced derivatives or educational tools may find it less fitting.

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.
