How comparisons and tools are built.

A comparison begins with eligibility

The US exchange table includes only providers in our existing catalog with documented US access. State and product exceptions stay visible. XRP buying has an additional asset-access check.

The hardware-wallet catalog checks manufacturer shipping and model support. A model marketed today is not a guarantee of inventory, a delivered price or access to an integrated exchange.

No inherited US score

The German ratings use their own market and criteria. The English table does not silently reuse a MiCA-centered score, change a score to fit a partnership or call a provider a US test winner without an applicable test.

Facts, estimates and scenarios

Fetched prices are labelled with source and fetch time. A ledger count is a network fact at a specific ledger. Assets-under-management divided by price is an estimate, not a verified list of fund wallets.

Calculator inputs are assumptions unless explicitly fetched from a source. Historical tests refuse uncovered dates. Forecast scenarios are calculations, not probabilities or promises.

Partner and source checks are independent

Official eligibility confirms product access. It does not confirm that a referral campaign accepts this domain, country or traffic source. Unverified US campaign eligibility remains unverified, even for a German partner.

What a public wallet cannot prove

A transfer into an address does not prove purchase date, price paid, ownership or taxable income. The wallet tool helps gather evidence; acquisition and legal records remain separate.
