I think you can do in a trust whatever you want. Old money has in the "laws" of their trust that all the money is invested in stocks or real estate. You could make your trust with Bitcoin & Lightning node or Mining hardware.

But I think you should ask yourself first why you even want to dictate what you children and descendants are allowed to do with inheritance? Isn't this unethical? If they want to blow it all on cocaine and hookers ... why patronize them from your grave? If they are responsible and of age?
