The bitcoin price has topped $90,000 per bitcoin, up 20% in a week, as traders eye $100,000 in the wake of Donald Trump's U.S. presidential victory, with Musk's "favorite" cryptocurrency dogecoin leading a price pump that's sent the combined market back over $3 trillion for the first time since 2021.

Musk and Vivek Ramaswamy were appointed by Trump to lead DOGE, which will function as an advisory committee outside of the government.
