"The matter was escalated to Twitter and the account has been immediately secured," the Indian Prime Minister's office tweeted on Sunday.
"In the brief period that the account was compromised, any Tweet shared must be ignored," officials warned.
When the Indian Prime Minister's personal Twitter account, @narendramodi, was hacked, several Twitter users tweeted screenshots of the tweet.
The screenshot stated, "India has officially accepted bitcoin as legal tender. The government has officially bought 500 BTC" and would be "distributing them to all residents of the country."
That tweet has since been removed from the internet. A probable fraud link was also included to the tweet.
Modi has more than 70 million Twitter followers, making him one of the most popular world leaders.
Bitcoin is not accepted as legal money in India.
El Salvador became the first government in the world to accept Bitcoin as legal payment in September, and the country's president, Nayib Bukele, announced last month that he plans to establish the world's first "Bitcoin City" — first funded by Bitcoin-backed bonds.
India has even considered outlawing cryptocurrency recently. Modi's government announced last month that it was working on a measure that would "prohibit any private cryptocurrencies in India." However, the bill's summary states that it would enable "limited exclusions to promote the underlying technology of cryptocurrency and its applications.”
There's a lot of space for interpretation in that phrasing. Because the bill doesn't define "private" cryptocurrencies, it's unclear whether that includes the world's most widely traded coins, such as bitcoin and ethereum. The Indian finance ministry did not react to CNN Business's concerns concerning the bill passed last month. In the current legislative session, it has yet to be presented.
