President-elect Donald Trump has expressed support for the bitcoin idea, which some economists see as inflationary and costly, depending on its implementation.

Bitcoin came within a whisker of closing above $100,000 for the first time on Thursday as the election of Republican Donald Trump as U.S. president spurred expectations that his administration will create a friendly regulatory environment for cryptocurrencies.

President-elect Trump's social media company is reportedly in advanced talks to purchase cryptocurrency exchange Bakkt as digital assets continue to soar.
