Choosing the right cryptocurrency payment processor can make or break an online business’s margins. With four prominent options dominating the market — NOWPayments, CoinGate, Cryptomus, and BTCPay Server — the decision often comes down to fee structure, setup complexity, and feature availability. For merchants evaluating their options, resources comparing btcpay server vs coingate vs cryptomus provide useful context alongside this detailed fee breakdown. Each platform takes a different approach to pricing, and understanding these differences helps you avoid unexpected costs as your volume grows.
NOWPayments
NOWPayments operates as a non-custodial payment gateway, meaning funds go directly to your wallet without intermediate holding. The base processing fee sits at 0.5% per transaction, which is competitive among multi-asset processors. The platform supports over 100 cryptocurrencies and offers both hosted checkout pages and API integration for merchants who want full control over their payment flow.
Beyond the standard fee, NOWPayments provides additional services that carry separate costs. Their crypto-to-fiat conversion service charges between 1.5% and 3% depending on the payout currency and region. Invoice creation is free, and recurring billing through their subscription tool does not add extra charges. Withdrawals to external wallets use network gas fees only — NOWPayments does not markup these.
Integration and Features
Setting up NOWPayments takes minutes. You create an account, select your preferred currencies, and receive API keys. The platform offers plugins for WooCommerce, Shopify, Magento, and other major e-commerce systems. For custom integrations, RESTful APIs are available in multiple programming languages.
The free plan includes basic invoicing, a merchant dashboard, and email notifications. Paid tiers unlock features like multi-signature support, advanced reporting, and dedicated account management. However, most small to mid-sized businesses find the free tier sufficient given the low base fee.
CoinGate
CoinGate has been operating since 2014 and supports payments in more than 200 cryptocurrencies. Their fee structure differs from competitors: 0.5% for crypto-to-crypto transactions and 1% when payouts go to fiat wallets. This makes CoinGate slightly more expensive for merchants who want direct bank deposits but reasonable for those staying entirely within crypto.
CoinGate also offers a developer card and business card that let users spend their crypto balances, though these are consumer-facing products rather than merchant tools. Their marketplace listing feature allows sellers to publish products directly on CoinGate’s platform, which carries its own commission beyond the payment processing fee.
Platform Strengths
CoinGate’s standout feature is its broad coin support, including lesser-known altcoins alongside Bitcoin and Ethereum. Their merchant dashboard provides settlement analytics, transaction history, and customer management tools. Payouts to bank accounts in Europe and select other regions typically settle within one to three business days.
One consideration: CoinGate is a custodial service for fiat settlements, meaning funds pass through their accounts before reaching your bank. If you prefer non-custodial routing, you would need to keep everything in cryptocurrency.
Cryptomus
Cryptomus entered the market more recently and positioned itself around aggressive pricing. The standard fee is 0.5% for regular merchants, dropping to 0.25% for high-volume operations exceeding $500,000 monthly turnover. This volume-based discount structure rewards scaling businesses more aggressively than many alternatives.
Cryptomus supports approximately 80 cryptocurrencies and offers instant conversions between assets within their platform. Their self-hosted solution option lets larger merchants run their own instance while still benefiting from Cryptomus infrastructure — a rare offering among the smaller processors.
Merchant Tools
The platform provides a clean API, webhook support, and plugins for popular CMS platforms. Settlement options include crypto wallets, bank transfers in multiple currencies, and stablecoin payouts. Customer-facing features include a customizable payment page, multi-language support, and automated receipt generation.
Cryptomus does not charge any hidden fees for account maintenance, API calls, or plugin usage. The main cost remains the per-transaction percentage, which scales down as your volume grows.
BTCPay Server
BTCPay Server takes a different approach entirely. It is open-source, self-hosted software with zero processing fees charged by the platform itself. Instead, you pay only the underlying payment processor or mining pool fees you configure — typically 0% when running a full Bitcoin node or around 0.1% to 1% when using third-party forwarding services.
The trade-off for zero fees is technical overhead. Running BTCPay Server requires a server (VPS or dedicated hardware), ongoing maintenance, and some familiarity with Bitcoin node operations. You are responsible for security, updates, and uptime. This makes it ideal for technically competent teams and organizations that prioritize sovereignty over convenience.
When BTCPay Makes Sense
Self-hosting pays off when transaction volume justifies the infrastructure cost. A business processing thousands of dollars monthly will save significantly on fees compared to any percentage-based processor. Smaller merchants may find the setup effort outweighs the financial benefit.
BTCPay Server also supports Lightning Network natively, enabling near-instant, near-zero-fee microtransactions. Neither NOWPayments, CoinGate, nor Cryptomus offer the same depth of Lightning integration out of the box. If you need Lightning capabilities without building them yourself, this becomes a decisive advantage.
Fee Comparison
The table below summarizes the core transaction fees for each processor under standard conditions:
| Processor | Crypto-to-Crypto Fee | Crypto-to-Fiat Fee | Minimum Volume Discount | Self-Hosted Option |
|---|---|---|---|---|
| NOWPayments | 0.5% | 1.5 – 3% | No | No |
| CoinGate | 0.5% | 1% | No | No |
| Cryptomus | 0.5% (0.25% above $500K/mo) | 0.5 – 1% | Yes | Yes |
| BTCPay Server | 0% (infrastructure cost only) | Depends on processor | N/A | Yes |
Hidden Costs to Watch
Beyond headline percentages, several secondary costs affect your true processing expense:
Network fees. Every on-chain transaction incurs blockchain miner fees. During periods of high network congestion, these can add noticeable cost per transaction, especially for smaller payments. Lightning Network mitigates this for Bitcoin, but not all processors support it equally.
Conversion spreads. When converting between cryptocurrencies or to fiat, exchange rate spreads can exceed the stated processing fee. NOWPayments and CoinGate both apply spreads during conversions that are not always visible upfront. Cryptomus discloses theirs in the dashboard. BTCPay Server lets you avoid spreads entirely by staying within your chosen assets.
Chargeback handling. Most crypto processors do not offer traditional chargebacks since blockchain transactions are irreversible. However, some platforms provide dispute resolution tools that may involve fees if you opt into mediated conflict resolution.
Which Processor Fits Your Business
If you need a simple, no-hassle setup and process under $100,000 monthly, NOWPayments or CoinGate deliver solid performance with minimal friction. Both handle the technical heavy lifting and let you focus on selling.
If volume is higher and you want lower rates without self-hosting, Cryptomus offers the best balance of low fees and ease of use, particularly once you qualify for the reduced tier.
If technical expertise is available and fee minimization is the top priority, BTCPay Server is unmatched. Zero platform fees combined with full control over your payment infrastructure make it the most cost-effective option for serious operators willing to manage the setup.
