How we score crypto exchanges
Every exchange on CryptoReview UK carries a single score out of 10. This page explains exactly where that number comes from, so you can check it yourself and decide how much weight to give it.
Quick answer
The CryptoReview UK score is a weighted average of four public rating sources, each normalised to a 0–10 scale: Trustpilot 35%, Reddit 25%, Google Play 20%, App Store 20%. It is recalculated automatically whenever a source rating is updated. It does not yet include first-hand testing, and we say so wherever the score appears.
How the aggregated score is calculated
Each source publishes a rating on its own scale (Trustpilot out of 5, app stores out of 5, Reddit sentiment as a percentage of positive mentions). We convert each one to a0–10 figure, multiply it by its weight, and add the four results together. The calculation runs inside our database every time a source figure changes, so the score on a review can never drift from the inputs shown in its score breakdown.
| Source | Weight | What it measures |
|---|---|---|
| Trustpilot | 35% | Verified and unverified customer reviews, especially on withdrawals, support and account closures. |
| 25% | Sentiment of mentions across UK and general crypto subreddits, which surfaces problems earlier than review sites. | |
| Google Play | 20% | Android app quality and stability from the store rating. |
| App Store | 20% | iOS app quality and stability from the store rating. |
Worked example: an exchange rated 8.0 on Trustpilot, 7.0 on Reddit, 9.0 on Google Play and 8.5 on the App Store scores (8.0 × 0.35) + (7.0 × 0.25) + (9.0 × 0.20) + (8.5 × 0.20) = 8.05 / 10.
Where each source comes from
Trustpilot figures are taken from the exchange's UK Trustpilot profile. App ratings come from the UK Google Play and App Store listings for the exchange's main consumer app. Reddit sentiment is our own read of recent threads mentioning the exchange, scored for the share of positive versus negative experiences. Every review page shows the four inputs individually under “Our Aggregated Score Breakdown”.
How often data is verified
Each review and comparison shows a “Last updated” date. That is the date the four source figures were last checked and, where needed, changed. FCA registration data is checked separately against the FCA Financial Services Register and each exchange's Firm Reference Number is quoted so you can verify it.
What we do not do
- No first-hand real-money testing yet. Today's score is entirely an aggregate of public ratings. We are building a tested layer (deposit time, real fees paid on a fixed buy, withdrawal time, KYC time) and will label it clearly and separately when it goes live.
- No price predictions or investment advice. We cover costs, safety and regulatory status, not which coin to buy.
- No paid placements. Exchanges cannot buy a position in a ranking or a change to a score.
Affiliate links and independence
Some links to exchanges are affiliate links and may earn us a commission if you sign up. Because the score is a fixed formula over public data, an affiliate relationship cannot change it. Our full policy is on the editorial policy page.
