The legal status of cryptocurrencies varies substantially from one jurisdiction to another, and is still undefined or changing in many of them.[1] Whereas, in the majority of countries the usage of cryptocurrency isn't in itself illegal, its status and usability as a means of payment (or a commodity) varies, with differing regulatory implications.[2]
While some states have explicitly allowed its use and trade, others have banned or restricted it. Likewise, various government agencies, departments, and courts have classified cryptocurrencies differently.
