Buyucoin is ideal if:

For users favoring convenience in India If you’re an Indian resident looking for a smooth, secure on-ramp from Indian Rupees to crypto with a friendly app and wallet, BuyUcoin is a great match.
For those exploring extra perks If you enjoy incentives like crypto cashback scratch cards, an OTC desk with zero fees, and a growing NFT ecosystem, BuyUcoin adds an engaging twist to your trading experience.
For beginners or casual traders If you value an intuitive interface, mobile-first design, and educational tools like webinars, BuyUcoin offers an approachable path into the crypto world without overwhelming complexity.

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.

Buyucoin isn’t ideal if:

If you prefer global fiat options BuyUcoin mostly supports INR deposits and limited alternative fiat methods, making it less suited for those needing diverse fiat integrations.
If fee clarity matters The platform’s fee structure isn’t fully transparent at first glance, which can frustrate users who demand simple, upfront cost breakdowns.
If you're targeting deep altcoin markets While BuyUcoin covers many popular tokens, serious altcoin traders may find the selection somewhat narrow compared to global multi-asset platforms.

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

BuyUcoin charges a flat trading fee of around 0.24 % for both maker and taker trades (including relevant taxes), without offering tiered volume discounts or reductions for using its 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

BuyUcoin does not currently offer futures or derivative contracts, so there are no maker/taker fees or funding rate mechanisms 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

Trading spreads for major pairs like BTC/USDT or ETH/USDT aren’t explicitly published on the platform, though users report that liquid pairs generally maintain competitive spreads thanks to its decent market depth.

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 deposit INR via bank transfers (including UPI, IMPS, NEFT/RTGS) or card options; bank-to-bank transactions typically have minimal processing delay and no direct fees, though instant cash-outs to cards may incur additional charges and processing time may vary.

methods, fees, timings

On-chain Withdrawals

Withdrawals of crypto assets are charged as fixed network-based fees (for example, BTC withdrawals are a set amount of BTC), not percentage-based, and rates differ by blockchain—BuyUcoin covers moving crypto between own wallets for free, but external transfers incur standard network fees.

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

Hidden Costs

BuyUcoin has no KYC or inactivity fees, nor storage charges, and sends within its own ecosystem incur no transfer fees; currency conversion costs are implicit in spreads rather than explicit charges.

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 convert €500 to BTC, you’d first use INR (so there’s currency exchange implied), pay a ~0.24 % trading fee embedded in the buy price, then face a spread implied in the rate, and finally incur a fixed network fee when withdrawing, depending on the specific chain—so your total cost would reflect trading fee + spread + withdrawal fee.

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

BuyUcoin currently lists over 170 cryptocurrencies, including most of the top-20 coins by market cap, offering a wide selection for spot trading across well-known tokens.

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 focuses on spot trading, OTC trades, staking (and earning through NFTs), recurring buys like SIPs, and an NFT marketplace—margin, futures, options, ETFs, and bots are not yet available.

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 precise figures aren’t published, liquidity for major pairs such as BTC and ETH is sufficient for smooth execution, though deeper institutional-level data and 24-hour volume statistics remain unclear.

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

Users get standard order types like limit and stop, along with charting via integrated views, but advanced features like OCO, native TradingView, alerts, or API access have limited visibility and may not be fully implemented.

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

BuyUcoin’s services are tailored for Indian residents only, with fiat options limited to INR; that means global availability of advanced products like derivatives or margin is restricted.

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 stands out with its NFT marketplace, SIP-based recurring crypto buys, cashback scratch cards, and flexible vs locked staking—features that reflect creative engagement rather than traditional financial tools.

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

BuyUcoin is legally operated by iBlock Technologies Pvt. Ltd, established in 2016 and headquartered in the Delhi-NCR region of India.

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

BuyUcoin is officially registered as a reporting entity under India’s Prevention of Money Laundering Act (PMLA) and holds registration with the Financial Intelligence Unit – India (FIU-IND).

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

Custody is handled in-house by BuyUcoin; there’s no publicly available proof of reserves, audit reports, or details on the proportion of assets held in cold storage.

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 are no public disclosures indicating institutional insurance or a protection fund covering user assets in the event of a breach or insolvency.

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

BuyUcoin has no recorded history of major security breaches, platform-wide suspensions, regulatory fines, or notable withdrawal freezes to date, based on public records.

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

Basic security measures like mandatory KYC and anti-money laundering policies are in place, but more advanced features—such as two-factor authentication, address whitelisting, anti-phishing tools, sub-accounts, or granular API permissions—are either limited or not visibly featured.

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 BuyUcoin participates in regulatory sandbox initiatives and maintains compliance reporting via FIU-IND, it does not offer monthly transparency reports, public wallet statements, or a formal service-level agreement (SLA) for uptime or responsiveness.

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

Bank transfers via IMPS, UPI, NEFT, and RTGS are available for depositing INR; there are no minimum or maximum amounts publicly listed, and funds usually arrive quickly depending on the chosen transfer method.

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)

BuyUcoin operates with mandatory KYC; beyond that, the platform does not publicly distinguish between basic or advanced tiers or provide specific transaction limits for each tier.

BigONE features two identity verification tiers

Withdrawals

Crypto withdrawals are subject to fixed network fees and processed on typical blockchains (e.g. BTC, ETH), with timing and limits largely dependent on network congestion and internal review standards, but multi-network options or daily caps aren’t explicitly disclosed.

limits, speeds & networks

Customer Support

Users can access support via help center articles, email, and live chat (when available), though response times vary; the platform also provides an FAQ section for self-help guidance.

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 interface operates in English and INR pricing, tailored primarily to Indian users; international fiat display or regulatory tailoring is minimal, as it focuses on the local market.

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 mobile app offers several security layers (2FA, PIN, biometric login) and promises fast deposit/withdrawal performance; while user feedback varies, recent updates suggest ongoing maintenance with occasional performance reports.

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

BuyUcoin presents a clean, mobile-first interface with both light and dark themes; onboarding is straightforward, minimizing friction, though it doesn’t offer distinct “Lite” or “Pro” modes.

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 in-house engine is said to process over 100,000 orders per second, contributing to fast order execution; while it appears reliable during normal activity, details on handling volatility spikes or KYC backlog during bull markets aren’t widely discussed.

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

Users benefit from online learning through webinars and real-time crypto news; however, there’s no dedicated academy, demo account, simulator, or Spanish-language resources currently available.

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

BuyUcoin fosters engagement via its referral program offering lifetime trading-fee commissions, and users can connect through its social media channels and forums, though there’s no official Discord or Telegram mentioned.

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 exchange supports smart trading strategies and copy trading options, but lacks native TradingView integration or tax accounting tools; however, third-party bot platforms can nonetheless connect to BuyUcoin.

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

BuyUcoin is ideal for Indian newcomers seeking a rewards-focused mobile experience with easy KYC and referral income; advanced traders seeking multi-asset tools or deep customization may find it less fitting.

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.
