(82)In order to ensure protection of their clients, crypto-asset service providers should have adequate arrangements to safeguard the clients’ ownership rights with respect to the crypto-assets they hold. Where their business model requires them to hold funds as defined in Directive (EU) 2015/2366 in the form of banknotes, coins, scriptural money or electronic money belonging to their clients, crypto-asset service providers should place such funds with a credit institution or a central bank, where an account with the central bank is available. Crypto-asset service providers should be authorised to make payment transactions in connection with the crypto-asset services they offer only where they are authorised as payment institutions in accordance with that Directive.
