Bitcoin stood on the verge of $90,000 on Tuesday, riding a wave of euphoria since the election of Donald Trump as U.S. president on expectations his administration will be crypto friendly. It is surging along with Elon Musk's automaker Tesla, which is up nearly 40% since voting results rolled in as investors figure Trump's friends and interests will do well while he is in office. "Obviously (it's) a clear Trump trade as he is so supportive of the industry, and this can only mean more demand both for crypto stocks as well as the currencies themselves," said Nick Twidale, chief market analyst at ATFX Global in Sydney.
