Dogecoin price rose to an all-time high of nearly 75 cents after Tesla CEO Elon Musk posted a promotional image of his SNL appearance. The picture showed Musk posing alongside two other SNL guest stars, with Dogecoin's mascot, a Shiba Inu, photoshopped in. Earlier, Dogecoin reportedly surpassed XRP to become the fourth-largest cryptocurrency by market capitalisation.
