The International Monetary Fund wants El Salvador to drop the highly volatile cryptocurrency Bitcoin as legal tender and strictly regulate the electronic wallet the government has pushed adoption of across the country.

The global lenders board urged the authorities to narrow the scope of the Bitcoin law by removing Bitcoins legal tender status, the IMF said in a statement Tuesday.

The adoption of a cryptocurrency as legal tender, however, entails large risks for financial and market integrity, financial stability and consumer protection, the IMF statement said.

President Nayib Bukele led the push to adopt Bitcoin as legal tender alongside the U.S. dollar. El Salvadors Legislative Assembly made the country the first to do so in June.

Tracing El Salvador’s journey of adopting bitcoin as legal tender

After nearly doubling in value late last year, Bitcoin has plunged and on Tuesday was slightly below where it was when the congress voted June 9. The Bitcoin law went into effect in September.

From the start there were concerns that a digital currency created to be beyond the control of governments would attract criminal activity. Bukele promoted the adoption as way for thousand of Salvadorans to avoid money transfer fees when relatives living outside the country sent home remittances.

El Salvadors law called for all businesses with the technological ability to accept Bitcoin as payment. The rollout was glitchy, but seems to have smoothed out.

Bukele became a darling of the cryptocurrencys promoters and has since spoken of building a Bitcoin city and issuing Bitcoin-backed bonds, something else some IMF directors expressed concern over.

Bukeles office said it did not immediately have a comment on the IMFs statement.
