Coinjar is ideal if:

Best for beginners: Its intuitive interface and built-in wallet features make buying, holding, and sending crypto simple—even if you’re new to the space
Great mobile experience: The sleek iOS and Android apps let you manage crypto conveniently on the go, with dependable support and solid security
Option for power users: The CoinJar Exchange platform delivers advanced, customizable trading layouts and tools for those who need greater control

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.

Coinjar isn’t ideal if:

Not for advanced traders: It lacks sophisticated tools like margin trading, futures, lending, or staking that power users often look for.
Limited crypto variety & regions: Offers fewer coin options and full functionality only in Australia and the UK, so global reach is constrained.
Suitable only for simpler needs: No demo accounts, investment advice, or educational overlays—so beginners seeking guided learning might not find that support.

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

CoinJar Exchange charges tiered maker/taker fees for fiat-to-crypto pairs—starting around 0.10% for both and reaching as low as approximately 0.02% maker / 0.06% taker at high volume—with zero maker fees on crypto-to-crypto and very low taker fees; there is no native-token discount system.

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

CoinJar does not support futures or derivative trading, so there are no associated maker/taker or funding costs.

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

Spreads aren’t published explicitly, but CoinJar Exchange advertises razor-thin spreads on liquid pairs backed by deep liquidity, catering especially to institutional 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

Fiat Deposits & Withdrawals

Fiat deposits and withdrawals via common routes (such as Faster Payments, SEPA, PayID) are typically free and fairly fast (ranging from minutes to a few business days), though wire transfers (especially USD via Fedwire) may incur a fixed fee (e.g., around USD 10/20) with processing times of several business days.

methods, fees, timings

On-chain Withdrawals

External crypto withdrawals are charged a dynamic network fee, recalculated every ~15 minutes based on blockchain congestion and transaction size, differing per coin (e.g. BTC, ETH, TRX), rather than a flat fixed fee.

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

Hidden Costs

CoinJar applies straightforward conversion fees (e.g., converting between fiat and crypto typically carries a flat 1%), and while there are no inactivity or express KYC fees, dispute or investigation requests can incur extra charges; currency conversion rates may also implicitly impact cost.

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

Suppose you use €500 to buy 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

Crypto Offering & Trading Features

Number of Coins & Pairs

CoinJar supports around 60 to 70 cryptocurrencies on the main platform, while the CoinJar Exchange offers roughly 380 to 390 trading pairs—many of which involve top-volume coins like BTC, ETH, ADA, DOT, LINK, SOL, and XRP depending on market dynamics.

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

CoinJar provides spot trading, recurring buys (DCA), and thematic crypto bundles, plus a crypto-linked Mastercard; however, it does not support derivatives like margin, futures, options, ETFs, copy trading, grid bots, or lending—staking isn’t yet officially offered via the platform.

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

CoinJar Exchange handles moderate daily trading volume in the low-millions of USD, and touts “ultra-deep liquidity” and a low-latency matching engine for its top pairs, ensuring narrow spreads and reliable order execution.

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

The platform supports standard order types—limit, market, stop, and OCO-style (time-enforced)—alongside customizable dashboards with chart overlays; it also offers documented APIs and WebSocket feeds for integration, though there’s no built-in TradingView interface.

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

CoinJar’s advanced trading tools (like CoinJar Exchange) are fully available only in supported jurisdictions (e.g. Australia, UK, select European countries), while derivative products are not offered anywhere—restricting professionals to spot and bundle offerings.

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

CoinJar continues innovating with features like auto-DCA via recurring buys and themed crypto bundles, but does not currently offer offerings such as launchpads, launchpools, or both flexible and locked earn programs.

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

CoinJar was founded in 2013 in Melbourne, Australia, and operates under CoinJar Australia Pty Ltd; it also maintains a registered presence in the UK through its London-based subsidiary.

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

CoinJar is officially registered with AUSTRAC in Australia and is also recognized by the UK’s Financial Conduct Authority as both a Cryptoasset Exchange Provider and Custodian Wallet Provider.

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

Customer assets are held via trusted third-party custodians (BitGo and Fireblocks), with over 90% stored in cold, multi-sig or MPC wallets; CoinJar maintains full backing of customer balances and undergoes regular security audits.

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

Institutional-level custody solutions include optional insurance coverage up to US $250 million for eligible clients; retail customer protection is built through secure infrastructure and audit readiness.

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

CoinJar has a strong safety track record with no known major hacks, system-wide suspensions, or regulatory fines, and has provided uninterrupted service since its founding.

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 robust security measures—mandatory 2FA, machine-learning based fraud detection, whitelists for trusted devices, encrypted API access with granular permission settings, and anti-phishing safeguards.

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

CoinJar offers real-time system status updates, maintains customer-friendly incident reporting, and operates with clear internal infrastructure processes—but does not publish public wallet addresses or monthly reserve reports.

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

CoinJar accepts deposits via bank transfer (wire in the US, PayID, FPS, or SEPA in supported regions), credit/debit card in some countries, and e-wallets where enabled; minimums and maximums vary by region and identity-verified status, and processing times range from near-instant (e.g. PayID, Faster Payments) to a few business days for standard transfers.

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)

Accounts must complete identity verification to unlock any transaction limits; before verification, deposit, withdrawal, and trading capabilities are restricted to zero, while verified accounts gain rolling daily and monthly limits tailored to their region.

BigONE features two identity verification tiers

Withdrawals

Crypto withdrawals are subject to dynamic network fees varying by blockchain; withdrawal limits and processing speeds align with verification status, and supported networks align with each coin (e.g., ERC-20, TRC-20) as shown post-login under account limits.

limits, speeds & networks

Customer Support

CoinJar provides support via email and a detailed self-help knowledge base, with availability during extended hours (typically local business hours into late evening), and generally responds within a business day—no 24/7 live chat, but clear help articles for common questions.

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 operates in English (with localized versions like US, UK, AU), displays fees in local fiat (e.g. EUR, USD, GBP), and tailors regulatory compliance messaging according to jurisdictions.

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 CoinJar mobile app is stable and regularly updated across iOS and Android, with few reported crashes; although exact crash rates aren’t published, user feedback indicates a smooth experience and frequent updates for performance and UI enhancements.

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

CoinJar offers a polished and intuitive interface that scales from beginner to professional use—while there’s no formal “Lite/Pro” toggle, the platform’s clean design adapts seamlessly from simple recurring buys to a fully customizable trading dashboard tailored for advanced users.

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

The platform’s upgraded matching engine ensures swift order execution and noticeably smoother performance during volatile periods, without documented service interruptions or KYC backlog issues—even during high-traffic bull markets.

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

CoinJar does not currently offer a dedicated academy, trading simulator, or demo mode, and educational materials remain primarily in English—Spanish-language support and interactive learning tools are not yet incorporated.

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

While CoinJar lacks public forums or an official Discord/Telegram community, it does support engagement through its blog, in-app news feed, and a referral program that encourages users to invite friends—though direct peer-to-peer community hubs are limited.

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

The mobile app now features integrated TradingView charts for enhanced technical analysis; additionally, CoinJar supports external tax and portfolio tools like CoinTracker, Koinly, and CryptoTaxCalculator via API or CSV integration—but there’s no formal marketplace for trading bots or accounting plugins.

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

CoinJar excels for casual investors and beginners who appreciate recurring buys, clean design, and mobile-friendly tools, while also meeting the needs of intermediate traders through its adjustable interface and integrated charting—though it may feel limited to users seeking demo accounts, Spanish-based learning, or vibrant community forums.

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.
