Bitcoin is legal in India. There is no ban on buying, selling, mining, and trading of digital assets in the country.
In April 2018, RBI had released a circular which had prohibited banks from providing services to companies dealing in cryptoassets. But on March 4 2020, the Supreme Court of India quashed this circular, stating, “the business of dealing in these (virtual) assets ought to be treated as a legitimate trade that is protected by the fundamental right to carry on any occupation, trade or business.”
In May 2020, RBI itself clarified that there is no ban on cryptoassets in reply to an RTI query.
