For example, when it comes to the obligation to produce reports, we know that banks have very important obligations in terms of submitting reports to FINTRAC and other organizations.
However, in your case and in the case of Bitcoin, there is no central administration. If I understand correctly, the whole principle consists in not having any kind of a centralized system.
Banks have to run checks when suspicious transactions are entered into the system, among other situations. When an operation is suspicious, we know that it may be related to crime or criminal activities.
In the case of bitcoin, when suspicious transactions take place and it is known that they are made for criminal purposes, who would be responsible for reporting them to the authorities to ensure that the case is well documented?
