Dogecoin rose to an all-time high Sunday, as Elon Musk tweets “Who let the Doge out” amid the rally.

The Shiba Inu-themed digital coin surpassed 8 US cents (10.67 cents) for the first time, just a week after crashing to 2.5 US cents and sparking an outcry on Reddit. It rose 53% in the last 24 hours to 8.2 cents as of 5.45pm in New York on Sunday, according to CoinMarketCap data, breezing through its recent record of 7.8 US cents posted in late January.

It now has a market value of US$10 billion, making it the 8th-biggest cryptocurrency.
