Unfortunately there does not seem to be enough legislation or international treaties in this regard given the decentralized and anonymous nature of cryptocurrencies, however there does seem to be some progress in some countries with respect to that possibility.

For example, in my country a new law has been approved that seeks to regulate the use of cryptocurrencies, which would imply that the user of them would benefit from legal protection against the risk of possible fraud, since the law is aimed at regulating the terms of service of those companies or organizations that accept cryptocurrencies to avoid them defrauding potential investors.
