Bill Miller, a seasoned Wall Street investor and founder of Miller Value Partners, advocated for the rise of Bitcoin (BTC) during a recent conversation with author William Green but voiced skepticism around many of the altcoins birthed during 2017. Miller subscribes to the well-documented thesis that Bitcoin portrays digital gold, and unlike many of his financial contemporaries — Warren Buffet being the most prominent — he has been a keen investor in the digital asset space. Back in early 2016, Miller dedicated 30% of his portfolio to the leading crypto asset Bitcoin at an average value of $500 and has more recently filed a motion with the SEC for Miller Opportunity Trust to invest in BTC via the institutional-grade $2.25 billion Grayscale Bitcoin Trust.
