Cryptocurrency is so completely run-through with scams, top to bottom, that frankly it needs to become a criminal violation of fiduciary duty to go anywhere near it if you are managing other people's money (and they have not explicitly consented to invest in crypto stuff). Do you manage a bank, and you touch crypto? Arrested. Do you manage a pension fund, and you touch crypto? Arrested. Are you in charge of a trust, or in some other way a caretaker of someone else's money, and you touch crypto? Arrested.

This needs to be done loudly and often to make it very clear to everyone involved in the business of managing others' money that they should treat everything even remotely cryptocurrency-related as radioactive.
