Yellow Card is ideal if:

Ideal if you prioritize local African access – it supports fiat on-ramps and local payment methods like mobile money, cash agents, and bank transfers across many African markets.
Perfect for simplicity and security – the user-friendly interface, strong AML/KYC processes, and embedded compliance make it approachable and trustworthy for new users.
Great for businesses needing robust infrastructure – with tools like embedded widgets, a Payments API, and invoice settlement, it's tailored for seamless crypto-fiat integration in emerging markets.

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.

Yellow Card isn’t ideal if:

Not for variety seekers – the platform offers a narrow range of cryptocurrencies, making it unsuitable if you want exposure to many or newer digital assets.
Limited advanced tools – lacking features like futures, staking, or analytic dashboards, it’s less suited if you're into sophisticated trading strategies.
Not ideal for non-African users – it’s built around African markets and local payment methods, so those outside this region may find it inconvenient or inaccessible.

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

Yellow Card does not use traditional maker or taker fees—instead, it applies a modest spread on spot trades, keeping the user experience simple without volume-based tiers or discounts tied to any native 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

Yellow Card doesn’t offer futures or derivative trading, so there are no associated maker/taker fees, funding charges, or leverage costs to consider.

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

The platform’s spread-based model keeps spreads consistently small for popular pairs, designed for clarity and predictability rather than frequent fluctuations tied to liquidity.

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

You can fund your account using bank transfers, mobile money, or cash-agents—with service fees that vary by channel (typically around 1–2%) and settlement times ranging from near-instant (in local mobile networks) to same-day for bank transfers.

methods, fees, timings

On-chain Withdrawals

Transfers on alt-chains like Polygon or Solana are free, while ERC-20 and TRC-20 stablecoin withdrawals carry a modest flat fee (about 1.5 USDT), and crypto withdrawals like BTC or ETH incur standard miner fees that adjust with network congestion.

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

Hidden Costs

There are no obscure charges like inactivity or express KYC fees; costs are transparent and tied to the payment method or network chosen, with currency conversions integrated into the pricing or spread rather than applied as additional hidden fees.

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 purchase €500 worth of BTC, your cost combines a small spread on the BTC price plus a service fee for converting your fiat (around 1–2%), and if you withdraw on-chain, a standard network fee applies—altogether designed to stay straightforward and avoid unexpected charges.

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

Yellow Card supports a limited selection of core assets—Bitcoin (BTC), Ethereum (ETH), Tether (USDT), Cardano (ADA), Solana (SOL), USD Coin (USDC), Polygon (MATIC), Celo Dollar (cUSD), Tether Gold (XAUt), and PayPal USD (PYUSD)—but does not provide a wide array of trading pairs or a ranked list by volume.

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

The platform specializes solely in spot buying and selling; it does not offer margin, perpetuals, options, crypto ETFs, staking or lending programs, copy trading, grid bots, or automated DCA features.

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

While there’s basic liquidity for BTC and ETH via spot trades and commercial OTC access, the platform does not publish typical 24-hour volume or book-depth metrics, so these indicators remain undisclosed.

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

Yellow Card provides simple buy/sell workflows with minimal advanced order types—no stop, limit, OCO, alert systems, in-app charts, or TradingView integration—but does offer an API and embeddable widget for businesses to integrate fiat-crypto on-ramps.

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

As derivatives and advanced trading products are not offered anywhere, there is effectively no geographic variation—only basic spot services are accessible across supported African markets.

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

The platform does not feature launchpads, launchpools, or different earn modalities; its innovation focus lies in seamless cross-border payments via Stablecoins, API integrations, and improving fiat on-ramp infrastructure.

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

The parent company, Yellow Card Financial Inc., was established in Delaware in 2016 and later converted into a C-corporation, with registered offices in Delaware and Alabama; it also operates through local subsidiaries across Africa to meet regional legal and tax obligations.

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

Yellow Card holds a Virtual Asset Service Provider (VASP) license from Botswana and a Crypto Asset Service Provider (CASP) license in South Africa, reflecting its commitment to working under formal regulatory frameworks in key African markets.

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 cryptocurrencies are securely held via Fireblocks infrastructure, using MPC-CMP to safeguard private keys and equipped with high-level security certifications and regular penetration testing; the platform itself does not engage in staking or borrowing with user assets.

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

Yellow Card does not offer explicit insurance or dedicated protection funds for user assets; instead, its security emphasis lies on institutional-grade custody and compliance rather than insurance-based safeguards.

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

There are no known reports or record of hacks, platform suspensions, asset freezing, or regulatory fines associated with Yellow Card, which suggests a clean operational history 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

Security controls include mandatory multi-factor authentication with options like 2FA and OTP, strong internal training and encryption protocols, real-time threat monitoring with auto-lock features, and robust anti-phishing guidance embedded in the platform experience.

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

While Yellow Card offers secure embedded infrastructure and compliance transparency, there is no indication that it publishes public monthly reports, maintains a viewable public wallet, or guarantees formal service levels (SLA) beyond its regulatory obligations.

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

Yellow Card enables deposits via mobile money, bank transfers (manual), and cash agents, with minimum amounts varying by country and reflecting local currencies; mobile money deposits are typically instant, while manual bank transfers may take up to 48 hours to reflect.

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)

Users begin at an introductory tier with basic identity information and limited functionality, with higher tiers unlocked through document and funding verification—each providing progressively higher deposit, withdrawal, and trading limits.

BigONE features two identity verification tiers

Withdrawals

Withdrawal options mirror deposit methods and differ by country; mobile money withdrawals tend to be quick, while bank transfers are slower, and on-chain crypto withdrawals use networks such as ERC-20 or TRC-20 where available, with specific limits tied to your KYC tier and jurisdiction.

limits, speeds & networks

Customer Support

Support is accessible via in-app chat 24/7 throughout the African operating regions, complemented by email assistance and a knowledge base to guide users through common issues or 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 app is localized in multiple African languages (Hausa, Swahili, Zulu, Yoruba, etc.), and displays amounts in both local fiat and USD, ensuring it fits the region’s linguistic and regulatory contexts.

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 core experience is delivered through native mobile apps on Android and iOS, optimized for stability and security; as of August 1, 2025, legacy access via web and older operating systems will be phased out to improve performance and maintain high reliability.

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

Yellow Card offers a clean, mobile-first interface designed for quick onboarding, especially for new users in Africa, with no “Lite” or “Pro” toggles—though businesses can use a more advanced API and widget for integration, while the app remains streamlined.

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 app is optimized for fast fiat-to-crypto conversions, even during peak demand, without reported crashes or slowdowns in high-volatility periods; KYC processes are integrated into the flow to minimize manual queues, particularly benefiting active 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

Yellow Card provides structured learning through its Academy initiative, boosted by Tether-powered financial literacy campaigns across African universities, though it does not currently offer interactive demos, simulators, or Spanish-language content.

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

A vibrant presence on platforms like social media complements their knowledge base, and they run targeted ambassador programs and referral campaigns—but there are no official community forums or Discord servers listed publicly.

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 platform emphasizes business integrations via its widget and Payments API for seamless fiat-crypto flows; however, it does not integrate with charting tools like TradingView, external trading bots, tax software, or accounting platforms.

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

Yellow Card is ideal for individuals and businesses in Africa seeking simple, secure, and compliant fiat-to-crypto on-ramps using local payment methods—but not for users looking for advanced trading features, educational simulators, or broad third-party tooling.

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.
