Simpleswap is ideal if:

Great for quick, no-registration swaps: Ideal if you want to exchange coins swiftly and privately, without creating an account or going through KYC.
Perfect for privacy-focused users: Its non‑custodial design helps you maintain full control over your assets throughout the transaction.
Suited for users exploring a wide range of coins: Offers an expansive selection of crypto assets—from mainstream to lesser-known altcoins—making it handy for flexibility and experimentation.

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.

Simpleswap isn’t ideal if:

Not for beginners needing fiat on-ramps: If you don’t already own crypto, SimpleSwap doesn’t support seamless fiat-to-crypto purchases without extra partner steps.
Limited for advanced traders: No margin, futures, charting tools, or sophisticated order types—only basic instant swaps.
Less suitable during network congestion: Transactions can slow when blockchains are busy, affecting speed and predictability.

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

SimpleSwap doesn’t distinguish between maker and taker fees—instead, all costs are embedded within the quoted exchange rate, so there are no separate fee tiers or native-token discounts to worry about.

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

SimpleSwap does not offer futures or other derivatives at all, so there are no associated maker, taker, or funding fees 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

Spread details aren’t openly published, but market comparisons suggest a mark-up hovering around 1.2%, meaning the price you see already includes a slight premium over market rates.

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 transactions are handled via a partner (like Mercuryo), typically using Visa or Mastercard, with fees built into the exchange rate and shown upfront—there’s no platform-stated flat rate or set timing for processing.

On-chain Withdrawals

There’s no separate withdrawal fee charged by SimpleSwap—only the blockchain’s own network (gas) fees apply, which vary by network and reflect real-time congestion levels.

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

Hidden Costs

There are no inactive-account fees or express-KYC charges; any currency conversion or rate-related cost is already baked into the exchange price, so you face no surprises beyond the displayed rate.

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 exchange €500 to BTC, the platform displays the rate including a small mark-up (around 1–2%) at the time, and then the final BTC received reflects that pricing, minus network fees; there are no extra line-item charges added afterward.

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

SimpleSwap supports over 1,500 cryptocurrency assets for instant swaps; while there’s no public list of the top 20 by trading volume, it’s safe to infer that mainstream heavyweights like BTC, ETH, USDT-based pairs, and other popular altcoins lead the most frequently exchanged.

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

SimpleSwap is designed solely for instant, spot crypto-to-crypto swaps and staking through integrated programs; it does not offer margin, futures/perps, options, crypto ETFs, lending, 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

Exact liquidity metrics like 24-hour trading volume or order-book depth aren’t published, but SimpleSwap sources liquidity from multiple partner exchanges, enabling smooth execution for BTC and ETH swaps via aggregation rather than a unified internal book.

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 is minimalist—neither limit nor OCO orders are available beyond fixed-and-floating rate swaps; it lacks advanced charting or alerts, though it does offer integration tools like APIs and widgets rather than a native 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

Since SimpleSwap doesn’t offer derivatives, there are no region-based limitations on those products specifically, but its fiat-to-crypto service is restricted in a set of countries flagged by regulatory or partner 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.

Innovation

While SimpleSwap doesn’t run launchpads or launchpools, it does innovate in passive earning via its loyalty and affiliate programs, offering flexible cashback and staking-like benefits rather than locking funds into fixed-term products.

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

SimpleSwap is operated by SimpleSwap Limited, established in 2018 and based in George Town, Cayman Islands, functioning under that jurisdiction while also listing a U.S. office in San Francisco for support operations.

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

The platform operates under money transmitter licenses where applicable, respecting relevant regulatory frameworks without explicitly holding licensing such as VASP registration or MiCA compliance, though its services may vary regionally to meet local requirements.

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

As a non-custodial exchange, SimpleSwap never holds user assets, reducing exposure to custodial risks; the platform does not currently offer public Proof of Reserves, cold reserve percentages, or external audit disclosures.

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

There is no public program offering insured coverage or asset protection funds—security relies on infrastructure practices like SSL encryption and secure transaction channels rather than third-party insurance.

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

SimpleSwap has maintained a clean record—no documented security breaches, funds seizures, or regulatory enforcement actions appear in public sources, reflecting a history free from major incidents.

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 strong security protocols including SSL encryption, optional two-factor authentication for added account safety, and compliance-driven KYC escalation in higher-risk cases; however, features like address whitelists, sub-accounts, granular API controls, or anti-phishing mechanisms are not prominently offered.

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

SimpleSwap does not provide regular reporting like monthly reports or SLAs, nor does it maintain public wallet addresses; its transparency relies on its non-custodial structure and clear service terms rather than open reserve disclosures or performance metrics.

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

SimpleSwap supports fiat deposits exclusively through its partner Mercuryo, typically via Visa or Mastercard, including virtual, debit, and credit cards, zero stated minimums or maximums, and instant payment processing, though processing limits are influenced by third-party policies.

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)

SimpleSwap enables anonymous crypto-to-crypto swaps without KYC, but using fiat services or large transactions may trigger partner-enforced identity verification (e.g., basic KYC via Mercuryo) depending on risk assessments, without predefined tiers disclosed.

BigONE features two identity verification tiers

Withdrawals

Since SimpleSwap is non-custodial, withdrawals simply reflect on-chain transfers to your wallet, with no platform-imposed limits; completion typically takes between several minutes up to an hour depending on network load and chosen blockchain.

limits, speeds & networks

Customer Support

SimpleSwap offers 24/7 live chat and email support with generally fast response times, backed by a detailed FAQ and blog guides that serve as a robust self-help resource.

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 is available in around 10 languages on the website (with app support in 6), displays pricing and rates in common fiat like EUR or USD based on your region, while service availability is tailored to local regulatory environments.

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

SimpleSwap’s mobile app is designed for smooth, user-friendly crypto swaps and applies the same core functionalities as the web platform; while precise crash rates aren’t published, user feedback reports high stability and ongoing updates to expand asset availability and app performance.

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

SimpleSwap’s interface shines with its minimalist design—there’s no “Lite” or “Pro” toggle, but the intuitive layout makes the learning curve nearly nonexistent, allowing users of all levels to initiate swaps quickly and effortlessly on both desktop and mobile.

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 generally executes instant swaps with low latency by sourcing multiple liquidity providers; while it doesn’t face order system overloads, swaps may take slightly longer during high blockchain congestion—there’s no bulk KYC process since accounts aren’t required.

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

SimpleSwap offers robust educational support via its blog, guides, and FAQs—but lacks demo or simulator tools; however, it caters to Spanish speakers with translated articles and interface options for enhanced accessibility.

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

Community engagement thrives through its ambassador and affiliate programs, offering users access to private Telegram groups, content support, and cashback incentives—though public forums or Discord channels aren’t prominently advertised.

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

SimpleSwap doesn’t embed TradingView charts or offer native bot support, but it does provide a transparent API and widget for smooth integration with external tools and developer workflows; no built-in tax or accounting tools are included.

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

SimpleSwap is ideal for both newcomers and seasoned crypto users who value instant, no-account swaps with strong privacy and multi-language support—especially useful when speed, simplicity, and broad coin access matter more than advanced trading tools.

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.
