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.

Changenow is ideal if:

You value privacy and self-custody — ChangeNOW is non-custodial and doesn’t require registration for most swaps, keeping you in full control of your funds.
You seek convenience and speed — It enables fast, no-account-needed swaps across a wide range of cryptocurrencies, ideal for quick, frictionless trades.
You want flexibility to upgrade — With ChangeNOW Pro, you can access optional perks like cashback, enhanced security, and better transaction tools when you're ready to level up.

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.

Changenow isn’t ideal if:

You want advanced trading features — If you're into charting tools, order types, margin, or futures, ChangeNOW's simple swap interface might feel too basic.
You expect swift, direct support — Without live chat or phone options, help is slower, often via tickets or messaging channels.
You prioritize strict regulation — ChangeNOW operates without formal licensing from leading financial regulators, which may concern users who value regulatory oversight.

Fees & Total Costs

Spot Maker/Take

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

ChangeNOW doesn’t operate with traditional maker/taker fee tiers—its costs are embedded in floating (or optionally fixed) exchange rates that vary by currency pair and volume, with no public tier schedule or explicit native-token discounts, though using the NOW token can yield rebate perks through cashback mechanisms.

Futures/Derivatives

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

ChangeNOW does not currently offer futures or derivative trading, so there are no maker/taker or funding fees of that type.

Average Spreads on Liquid Pairs

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

While ChangeNOW doesn’t publish spread data, it sources liquidity from partners and embeds margin within the quoted floating rate—spreads are typically competitive and dynamically adjusted based on real-time market conditions.

Fiat Deposits & Withdrawals

methods, fees, timings

Fiat purchases on ChangeNOW are facilitated through third-party providers (e.g., Simplex, Transak, Guardarian) using Visa or Mastercard; fees depend on the provider (typically a few percent), and processing times range from near-instant to several minutes.

On-chain Withdrawals

fixed vs dynamic fees (BTC, ETH, TRX, etc.)

ChangeNOW doesn’t charge separate withdrawal fees—network (mining) fees are passed through as dynamic costs based on the chosen blockchain (e.g., BTC, ETH, TRX), reflected in the quoted rate rather than stated separately.

Hidden Costs

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.

ChangeNOW doesn’t impose inactivity penalties or hidden fees; currency conversion and network fees are included in the exchange quote, and express KYC (if triggered) depends on transaction specifics, with any associated costs transparently presented before confirmation.

Real-World Cost Example: “€500 BTC

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

Suppose you buy €500 worth of BTC via ChangeNOW’s fiat gateway—the quote would include the provider’s purchase margin (around a few percent), underlying spread to liquidity, and on-chain sending fee, all bundled in the total you see before confirming purchase.

Crypto Offering & Trading Features

Number of Coins & 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.

ChangeNOW supports over 1,225 cryptocurrencies and more than a million exchange pairs, giving you access to virtually any major or niche token in the market.

Product Range

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.

ChangeNOW offers instant spot swaps, non-custodial swaps, native wallet staking, and crypto-backed loans via ChangeNOW Pro, but it does not currently provide margin, perpetuals, options, ETFs, copy trading, grid bots, or automatic DCA.

Liquidity

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.

Liquidity is aggregated through multiple exchange partners, ensuring robust 24-hour volumes and order depth for major assets like BTC and ETH—even though precise statistical metrics are not publicly disclosed.

Tools

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.

The platform refrains from offering advanced tools—no limit, stop, OCO orders, custom alerts, charting, TradingView integration, or APIs are openly provided; its focus is on simplicity and instant swaps rather than complex trading infrastructure.

Geographic Restrictions by Product

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

As a swap-first platform, ChangeNOW does not typically impose product-based geographic blocks, but advanced features like Pro loans or staking may have regional restrictions depending on local compliance and third-party partner availability.

Innovation

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.

While ChangeNOW lacks crypto ETFs or launchpad offerings, it has innovated in token utility—offering automatic staking of its native NOW token in Pro accounts, flexible crypto loans collateralized with major coins, and easy wallet-integrated staking in NOW Wallet.

Security, Regulation & Custody

Operating Entity & Jurisdiction

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.

ChangeNOW is operated by CHN Group LLC, registered in Saint Vincent and the Grenadines, with roots dating back to 2017 and additional administrative presence in the Netherlands. (Information compiled from official sources.)

Licenses/Registration

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.

While it doesn’t hold specific exchange licenses or operate as a regulated VASP (Virtual Asset Service Provider) under frameworks like MiCA, ChangeNOW complies with global AML/KYC mandates by triggering identity checks when its risk engines flag transactions.

Custody

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.

The platform is primarily non-custodial—users send and receive directly from their own wallets—but offers optional custodial service via ChangeNOW Pro Custody (a hot wallet model). It does not publicly share PoR, audit results, or precise cold storage ratios.

Insurance & Protection Funds

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.

There’s no public mention of insurance coverage or dedicated asset protection funds, though ChangeNOW demonstrates active anti-fraud and risk-response measures when unauthorized activity is detected or reported.

Incident History

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.

ChangeNOW has a strong track record of catching suspicious transactions in real time—successfully halting and assisting recovery of funds in cases like SIM-swap thefts and phishing scams, working with law enforcement to return millions to victims.

Risk Controls

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.

The platform enforces automated AML checks, address whitelisting for Pro users, and KYC triggers as needed. However, it doesn’t offer typical user security features such as 2FA, sub-accounts, granular API permissions, or anti-phishing tools.

Transparency

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.

ChangeNOW publishes trust-focused updates—highlighting recovered funds and AML activity—but does not provide continuous transparency tools like public wallets, monthly reserve reports, or service-level agreements (SLAs).

Deposits, Withdrawals, KYC & Support

Fiat Deposit Methods

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.

ChangeNOW facilitates fiat-to-crypto purchases through third-party partners such as Simplex, Transak, and Guardarian, enabling payment via Visa/MasterCard, Apple/Google Pay, SEPA, SWIFT, PIX, Revolut, and more. Minimum purchase amounts typically start around $50 (or equivalent), with no firm maximum on classic exchanges, and most transactions finalize within minutes though timing can vary by provider and method.

Supported Fiat Currencies & Conversion

KYC (Verification Levels)

BigONE features two identity verification tiers

ChangeNOW generally operates registration-free and KYC-free for smaller transactions, but it may prompt identity verification via its third-party partner if transactions are large or flagged. Completing KYC under the Pro tier unlocks higher transaction and withdrawal limits, rate advantages, and additional Pro features, with verification typically processed in minutes.

Withdrawals

limits, speeds & networks

On-chain crypto withdrawals occur across supported networks—like ERC-20, TRC-20, BEP-20, etc.—and are processed in real time based on network conditions; there are no preset withdrawal limits for classic exchanges, though Pro users may benefit from elevated thresholds.

Customer Support

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.

ChangeNOW offers 24/7 customer support via live chat and email/ticket systems, backed by a comprehensive help center. Response times are generally quick (particularly via live chat), and its self-help knowledge base covers most common topics—though dedicated response patience may vary depending on case complexity.

Languages & Localization

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.

The platform supports multiple languages (around 15) and displays pricing in common fiat formats (€, $, etc.), offering localized experiences in many regions; however, availability of features and compliance may differ by jurisdiction.

App Quality & Stability

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.

The ChangeNOW mobile apps are available on Android and iOS and deliver a streamlined experience for swaps; while formal crash-rate data isn’t public, user rankings are strong (around 4.7–4.8/5 on app stores), and the app receives regular updates to enhance performance and fix bugs.

Experience, Performance & Ecosystem

UX/UI

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.

The platform features a clean, intuitive interface ideal for beginners—swaps proceed in just a few clicks—while the Pro tier introduces a richer dashboard with transaction history, analytics, cashback tracking, and more advanced features tailored to power users

Performance

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.

ChangeNOW delivers near-instant swap execution thanks to its aggregator model, even during volatile periods; KYC processing within Pro remains efficient, and there’s no known backlog during bull-market surges.

Education

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.

While there’s no formal academy or simulation tools, ChangeNOW provides educational articles (especially via its blog) covering topics like crypto strategy and security practices—though Spanish content appears limited

Community

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.

Community engagement centers around Telegram, Twitter Spaces AMAs, and blogs; additionally, ChangeNOW rewards referrals with customizable affiliate links offering commission—developers and partners can integrate swaps via widget, API, or bot for seamless referrals

Integrations

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.

ChangeNOW offers a robust API with 99.99% uptime and sub-second response times, enabling integration into bots, widgets, or partner platforms; while there’s no native TradingView or tax tool, users can export swap history via CSV for external accounting or analytics

Who Each One Is Best For

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.

The platform shines for users who seek fast, private, no-frills crypto swaps—regular users will appreciate the simplicity of the Lite experience, while frequent traders and businesses benefit from Pro’s added tools, cashback, loans, and AML features.
