I agree that many governments have yet to accept crypto for fear that many people will join and lose money by crypto-related scam projects. However, as far as I can see, even when they have not yet accepted, a lot of investors still join ponzi projects and lose money. If the government saw this as a solution, it would have failed completely.
I think it is necessary to enact the legal framework. It specifies issues related to investment & activities of organizations & individuals in the crypto sector, forms of handling fraudulent projects, taxation on crypto income and plan on education, adoption, development of crypto.
