Bitcoin services: terms, custody and responsibility

Self-custody puts key management and recovery in the user's hands. Custodial service adds dependence on a provider; it may simplify operation but does not transfer all your risks to that provider. The provider manages keys; the app balance is its record. Executing a withdrawal depends on its processes, terms and availability. Proof of Reserves may demonstrate selected assets at a particular moment. It may not include all liabilities, encumbrances or client rights and is not a solvency guarantee.

Running BTCPay Server yourself involves deployment choices, maintenance and support; hosting and custody of funds are separate questions. Trading through Bisq has counterparty, payment and dispute rules; P2P does not mean an absence of conditions or risks. These are examples from specific documentation, not descriptions of every service or version. Before use, check country eligibility, identity verification, payment method, total costs, limits and withdrawal terms. Legal protection depends on the contract, product and country. This directory does not rank or recommend services or promise current availability. Linked entries have their own sources and reviews.
