Crypto Exchanges: Our Review Criteria and What Matters

Reviewed: June 2026  |  Reviewer: Crispus Nyaga  |  Next review scheduled: December 2026

Choosing a cryptocurrency exchange is one of the most consequential decisions a crypto participant makes. Exchanges hold user funds, execute trades, and in many jurisdictions function under financial-services regulation. This page explains how The Market Periodical assesses exchanges and what factors separate a credible platform from a dangerous one. We follow a structured methodology — see our Reviews Methodology for the full process. Some links here may be affiliate links; read our Affiliate Disclosure before acting on any recommendation.

Regulatory Status and Jurisdiction

The single most important factor we evaluate is whether an exchange operates under a recognised regulatory framework. This includes licensing status in the jurisdictions where it actively markets to users, compliance with Anti-Money Laundering (AML) and Know Your Customer (KYC) obligations, and whether it has been subject to enforcement actions. An exchange that evades regulatory scrutiny may offer lower fees in the short term but exposes users to the risk of sudden shutdowns, frozen withdrawals, and legal uncertainty over fund recovery.

We note that regulatory frameworks differ significantly by country. What is compliant in one jurisdiction may be illegal in another. We always flag the jurisdiction context of any exchange we discuss.

Security Infrastructure

We examine the proportion of assets held in cold storage versus hot wallets, the history of security incidents and how they were handled (including user reimbursement policies), whether the exchange publishes regular proof-of-reserves attestations, the availability of two-factor authentication options (preferring hardware keys over SMS), and whether withdrawal address whitelisting is available.

Fee Transparency

Exchanges monetise through trading fees (maker/taker spreads), withdrawal fees, deposit fees, and in some cases spread markups on quoted prices. We map all fee layers clearly, because the headline trading fee is often not the total cost. We also look at whether fee schedules are published clearly in advance or buried in terms of service.

Liquidity and Market Depth

An exchange with thin order books can result in significant price slippage — the difference between the price you expect and the price you receive. We assess liquidity not just for major pairs (BTC/USDT) but for mid-cap assets where depth matters more, using publicly available order book data rather than self-reported volume figures, which can be manipulated.

Customer Support and Fund Recovery

We review the availability and responsiveness of customer support, the presence of a documented process for account recovery and dispute resolution, and whether the exchange maintains a segregated insurance fund or has obtained third-party insurance for user assets. Exchanges that offer 24/7 support with documented escalation paths score better than those with only ticket systems and slow response times.

What Good Looks Like

• Valid regulatory licences in all major markets where the exchange operates.
• Proof-of-reserves published regularly by a recognised auditing firm.
• Clear, complete fee schedules with no hidden spread markups.
• Strong default security (mandatory 2FA, withdrawal whitelisting, login alerts).
• A documented incident history with transparent communication and user reimbursement where losses occurred.

Warning Signs

• Offshore registration with no meaningful regulatory oversight.
• No proof-of-reserves or audited financials.
• Unusually high advertised trading volume relative to market position (may indicate wash trading).
• Withdrawal delays that cannot be explained by standard security procedures.
• Aggressive referral incentives that reward volume over user suitability.

A Note on Risk

Even well-regulated exchanges carry counterparty risk. Funds held on any exchange are not equivalent to funds held in a self-custodial wallet. We recommend users hold only the assets they intend to actively trade on any exchange platform, and withdraw the remainder to self-custodial storage.
