Every crypto asset recorded in the property and interest declarations filed with the Bulgarian Court of Audit — which coin, how much of it, and the value put on it. The declarations cover MPs, cabinet members, mayors, councillors and agency heads, so this register is not tied to a single institution.
The value is the one the declarant stated at the time of filing, not a current market price. The same asset is re-declared on every filing that covers it, so the default view shows one year per person; „all years" gives the full history.
