Our Methodology: How We Review & Rank Crypto Exchanges
Our Methodology: How We Review & Rank Crypto Exchanges
Written by AffMiss Editorial · Updated:
Every exchange review and ranking on AffMiss follows a fixed, repeatable methodology. We test each exchange with real accounts, real deposits, and real trades. Ratings are calculated from a weighted scoring system across five categories. No exchange can pay for a higher score. This page explains exactly how we arrive at every number.
Scoring System: 5 Categories, Fixed Weights
| Category | Weight | What We Measure |
|---|---|---|
| Security | 30% | Cold storage ratio, proof-of-reserves frequency, audit firms, insurance fund, hack history, certifications (SOC 2, ISO 27001, CertiK rating), regulatory licences |
| Fees | 25% | Maker/taker fees (spot + futures), withdrawal fees, deposit fees, fee tier structure, BNB/token-based discounts, hidden costs (funding rate premiums, spread markup) |
| Trading Features | 20% | Order types (limit, market, OCO, TWAP, iceberg), charting tools, API quality, copy trading, trading bots, options/derivatives product range, mobile app |
| Liquidity | 15% | 24h trading volume, order book depth (BTC/USDT top-of-book spread), slippage on $50K and $100K market orders, number of trading pairs |
| User Experience | 10% | Account creation time, KYC speed, interface clarity, customer support response time, educational resources, fiat on-ramp options |
The final score is a weighted average: Score = (Security × 0.30) + (Fees × 0.25) + (Features × 0.20) + (Liquidity × 0.15) + (UX × 0.10)
Each category is scored on a 1–5 scale (5 = best in class). The weighted total produces a score out of 5.0, displayed as a star rating on every review page. Security carries the highest weight (30%) because after FTX, exchange solvency and fund safety are the most critical factors for traders.
How We Test Each Exchange
| Phase | What We Do | Data Collected |
|---|---|---|
| 1. Account setup | Register a new account, complete KYC verification | Registration time (minutes), KYC approval time (hours/days), documents required, geo-restrictions |
| 2. Deposit | Deposit via crypto (BTC, USDT) and fiat (where available) | Processing time, minimum deposit, fiat methods accepted, on-ramp fees |
| 3. Spot trading | Execute 5+ spot trades on BTC/USDT using limit and market orders | Actual maker/taker fees charged (verified against published schedule), spread, fill time |
| 4. Futures trading | Open and close 5+ perpetual futures positions with varying leverage | Fee rates to 4 decimal places, funding rate, liquidation price accuracy, margin modes available |
| 5. Withdrawal | Withdraw crypto to an external wallet, withdraw fiat (where available) | Processing time, withdrawal fee, minimum withdrawal, confirmation speed |
| 6. Platform testing | Test charting tools, order types, mobile app, API endpoints | Chart load time, order types available, API latency, app stability |
| 7. Support testing | Submit a support ticket and measure response | Response time (hours), resolution quality, live chat availability |
| 8. Security audit | Verify proof-of-reserves, insurance fund, cold storage claims, regulatory filings | PoR frequency, audit firm, reserve ratios, licence jurisdictions, hack history |
We complete all 8 phases for every exchange before publishing a review. The entire process takes 5–10 business days per exchange.
Data Standards
| Standard | How We Apply It |
|---|---|
| Fee precision | All fees reported to 4 decimal places (e.g. 0.0200% maker, not “low fees”) |
| Time precision | Processing times in hours or minutes, not “fast” or “slow” |
| Volume data | 24h trading volume sourced from CoinGecko or CoinMarketCap, cross-referenced with exchange API |
| PoR data | Reserve ratios sourced from published audit reports (Hacken, Mazars, etc.), not exchange marketing |
| Regulatory data | Licence status verified against regulator databases (MAS, AUSTRAC, VARA, FCA, MiCA registry) |
| Source citation | Claims cite original sources: exchange fee pages, regulatory filings, on-chain data, auditor reports |
| Last verified date | Every review displays a “Last Verified” date. We re-verify data when fees, features, or regulatory status change. |
How Rankings Work
Our Best Exchange Rankings (Best Futures Exchange, Best for Beginners, Lowest Fees, etc.) use the same 5-category scoring system but apply category-specific weighting adjustments based on the ranking’s focus:
| Ranking | Primary Weight Adjustment | Rationale |
|---|---|---|
| Best Futures Exchange | Features ↑ to 30%, Liquidity ↑ to 20% | Futures traders need advanced order types and deep order books |
| Best for Beginners | UX ↑ to 25%, Security ↑ to 35% | New traders need simple interfaces and maximum fund safety |
| Lowest Fees | Fees ↑ to 40% | Fee-focused ranking prioritises cost above all else |
| Most Secure | Security ↑ to 50% | Security-focused ranking weighs hack history, PoR, and licences most |
| Best Copy Trading | Features ↑ to 35% (copy-specific) | Evaluates copy trading depth, lead trader pool, and profit-sharing models |
The base scoring data remains the same. Only the weights shift to match what matters most for each ranking’s audience.
How Comparison Articles Work
Our head-to-head comparisons (e.g. Binance vs Bybit, Bybit vs Bitget) follow three rules:
Neutral framing. We present data side-by-side and let readers decide. We state which exchange wins each category but do not push one platform over the other. If Exchange A wins on fees and Exchange B wins on security, we say that — not “Exchange A is better.”
Same data points. Both exchanges are compared on identical metrics: fees, leverage, pairs, volume, PoR, licences. No selective data that favours one side.
Affiliate disclosure. Both exchanges in a comparison may be affiliate partners. The comparison outcome is not influenced by commission rates. We disclose all affiliate relationships on every page.
Editorial Independence & Affiliate Disclosure
AffMiss earns revenue through affiliate partnerships with exchanges including Binance, Bybit, OKX, Deribit, Bitget, MEXC, Gate.io, BingX, and others. When you click an affiliate link and create an account, we may earn a commission at no extra cost to you.
Affiliate relationships do not influence scores, rankings, or editorial content. Our scoring weights are fixed and published on this page. An exchange cannot purchase a higher rating. If an affiliate partner scores lower than a non-partner on our methodology, the non-partner ranks higher. We have published reviews with 3.5–4.0 scores for affiliate partners when the data supports it.
All affiliate links are marked with rel="nofollow sponsored" as required by Google’s guidelines and FTC disclosure standards.
Corrections & Updates
If we publish an error, we correct it within 24 hours and note the correction at the top of the affected article. If an exchange changes its fee structure, security features, or regulatory status, we update the review within 7 days and change the “Last Verified” date.
