Tesla (NASDAQ: TSLA ) Inc boss Elon Musk said on Wednesday that a Tesla vehicle can now be purchased using bitcoin and that the option will be available outside the United States later this year.

“Now you can buy a Tesla with bitcoin,” he tweeted on Wednesday. “Bitcoin paid to Tesla will remain as bitcoin, it will not be converted to fiat currency.”

Last month, Tesla revealed that it had bought $1.5 billion worth of Bitcoin and would soon accept it as payment for cars, sending the price of the world’s most popular cryptocurrency skyrocketing.
