Where is cryptocurrency legal?

A better question might be “where is cryptocurrency NOT legal”.

Cryptocurrency is legal in most countries and only banned in a few. Some examples of countries which have banned cryptocurrency are China, India, Russia, Vietnam, Bolivia, Ecuador, and a few others. Some of these bans may only be temporary as these countries reevaluate their position on the subject.

Most other countries allow cryptocurrency with no limitations or at least have some government imposed regulations.
