Coinex is ideal if:

Privacy-minded traders: you can trade without mandatory KYC up to high limits, offering anonymity while retaining full platform access.
Global assets explorer: the platform supports a wide variety of crypto tokens alongside features like strategic trading (Auto-Invest, Spot Grid), making it great for exploring diverse markets.
Security-focused users: with multi-signature wallets, rigorous cold-storage, and committed proof-of-reserves, your funds benefit from robust protection.

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.

Coinex isn’t ideal if:

Strictly fiat-only traders: CoinEx doesn’t support direct fiat deposits or withdrawals; you must use third-party gateways if you want to convert between crypto and traditional currencies.
Regulation-focused investors: It lacks licensing from top-tier regulatory bodies, which may concern users seeking exchanges with clear, formal oversight.
Complete beginners seeking hand-holding: Educational resources and customer service can be less responsive or comprehensive, which may not suit those needing more guidance.

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

Spot trading fees decrease as your 30-day trading volume, CET balance, or VIP level increases—higher tiers enjoy lower maker and taker rates, with an extra discount if you opt to pay using the native CET token.

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

Futures trading applies different maker and taker fees based on VIP status, and while CoinEx doesn’t charge funding directly, perpetual contracts settle funding between long and short positions every 8 hours (or more frequently under extreme conditions).

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

Although CoinEx doesn’t publish spread figures directly, mainstream spot pairs like BTC/USDT and ETH/USDT generally exhibit tight spreads typical of mid-to-high liquidity venues, making execution costs reasonably competitive for active traders.

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

Currency Conversion, Inactivity, Express KYC, etc.

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

If you buy €500 worth of BTC on CoinEx, your total cost comprises the third-party gateway’s currency conversion rate plus its service fee, the spread between buy and sell prices, and the dynamic on-chain withdrawal charge—so the final amount received in your wallet will be less than the gross purchase value due to these combined factors.

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

Number of Coins & Pairs

CoinEx lists over 800 cryptocurrencies and supports more than 1,200 trading pairs, including its most actively traded tokens ranked among the top 20 by volume, which typically consist of mainstream assets such as BTC, ETH, TRX, and a range of emerging altcoins.

Liquidity

CoinEx maintains solid liquidity, especially on BTC and ETH markets, reflected by consistently vigorous 24-hour trading volume and deep order-book depth that supports efficient execution even during volatile periods.

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

You’ll find a robust toolkit featuring common order types like limit, market, stop-limit, plus advanced modes such as OCO and maker-only, along with real-time alerts, charting, API/WebSocket access, and built-in TradingView integration for sophisticated analysis.

Geographic Restrictions by Product

While CoinEx is globally available in over 200 countries, certain products like derivatives and copy trading may be restricted in jurisdictions such as the U.S., Canada, Hong Kong, and China due to regional regulatory limitations.

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

Security, Regulation & Custody

Operating Entity & Jurisdiction

The exchange began in 2017 and is operated under the ViaBTC ecosystem, with its legal base and main offices located in Hong Kong.

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

CoinEx holds registration as a Virtual Asset Service Provider (VASP) in certain jurisdictions such as Estonia and complies with applicable regulations, but it does not currently fall under the EU’s MiCA framework.

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

CoinEx uses its own custody infrastructure with both hot and cold wallets, enhanced by multi-signature security. It publishes frequent Merkle-tree-based Proof of Reserves—maintaining a 1

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

The platform supports its risk management with a “Shield Fund,” which redirects around 10% of fees into a reserve designed to buffer against extreme or unexpected market shocks

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

Since its 2017 launch, CoinEx has maintained a clean security record with no known hacks, outages, freezing of accounts, regulatory fines, or major incidents to date

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

CoinEx implements strong safety protocols, including two-factor authentication (2FA), address whitelisting, anti-phishing measures, support for sub-accounts, and granular API permission controls, designed to minimize unauthorized access and bolster overall platform 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

The platform demonstrates transparent practices through monthly reserve updates, publicly verifiable wallets using Merkle trees, and clear communication via announcements—though formal SLA commitments are not prominently outlined.

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

CoinEx offers fiat deposits through partnerships with eight external providers like MoonPay, Banxa, Simplex, Mercuryo, Paxful, Guardarian, XanPool, and Advcash, enabling methods such as Visa/MasterCard, Apple Pay, UPI, SEPA, bank transfers, Revolut, and PIX. Minimum and maximum order limits vary by provider, and most transactions are completed within around 30 minutes once initiated.

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)

CoinEx features progressive verification tiers—from no-KYC to Basic and Advanced levels—with the scope of trading and withdrawal increasing by tier; higher KYC levels unlock significantly elevated withdrawal capacities.

UX/UI

Performance

The platform boasts a high-speed matching engine built to handle order execution with minimal delay, and though official latency metrics aren’t public, user feedback suggests trading remains responsive even during volatility spikes; KYC processing tends to scale adequately, though verification backlogs can surface during market surges.

Who Each One Is Best For

The platform suits growth-minded individuals who value a balance of clarity and strategy—newcomers benefit from educational tools and a clean interface, while seasoned traders can leverage demo trading, strategic tools like grid bots, and active community programs to refine their approach.

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.
