1. Any natural or legal person or such persons acting in concert who have taken a decision either to acquire, directly or indirectly, (the 'proposed acquirer') a qualifying holding in a crypto-asset service provider or to increase, directly or indirectly, such a qualifying holding so that the proportion of the voting rights or of the capital held would reach or exceed 20 %, 30 % or 50 % or so that the crypto-asset service provider would become its subsidiary, shall notify the competent authority of that crypto-asset service provider thereof in writing indicating the size of the intended holding and the information required pursuant to the regulatory technical standards adopted by the Commission in accordance with Article 84(4).

2. Any natural or legal person who has taken a decision to dispose, directly or indirectly, of a qualifying holding in a crypto-asset service provider shall, prior to disposing of that holding, notify in writing the competent authority of its decision and indicate the size of such holding. That person shall also notify the competent authority where it has taken a decision to reduce a qualifying holding so that the proportion of the voting rights or of the capital held would fall below 10 %, 20 %, 30 % or 50 % or so that the crypto-asset service provider would cease to be that person's subsidiary.
