How we rate

Every value we show comes from the provider's own pages: its terms, help center, app or code. We record when it asks for ID, its limit without ID and what its terms say happens to your coins if a check fails, each with the page and the date we checked it. Where its own pages disagree, we show both sides. How we rate

Our process

We take fees, availability, licenses and coin counts from primary sources: each provider's own fee schedules, terms and help pages, and the public registers kept by regulators. Every value carries the date we last checked it. The values on this page were checked between October 14, 2026 and October 23, 2026.
