Grayscale, who owns 3% of all BTC and 1% of all ETH in circulation, said it attracted $115 million in BTC purchases in the last 24 hours, adding to its $9.8 billion in assets under management (AUM). Grayscale Bitcoin Trust is a financial vehicle that enables investors to trade shares in financial trusts holding large pools of bitcoin. Shares in the fund track the price of Bitcoin, but only roughly. In April, Grayscale said it bought about 50% of all newly mined ethereum in the year, holding the equivalent of 1.1% of all ETH in circulation. Grayscale has profited dearly from surging institutional interest in bitcoin, such as PayPal’s accelerated timetable for launching their crypto exchange, as well as Jack Dorsey's Square and Michael Saylor's MicroStrategy. On Thursday, all eligible PayPal accounts in the U.S. can now buy, hold and sell bitcoin, ether, and litecoin. Barry Silbert, the CEO of Grayscale who heads the Digital Currency Group, explained recently that half of U.S. investors reported in a survey they were interested in investing in Bitcoin in 2020, a significant increase from 36% in 2019. Silbert said a tweet this morning, "$200 million to go," while referencing Grayscale's whopping $9.8 billion in AUM, which quickly approaches $10 billion. Grayscale’s model benefits from the strict absence of a U.S. Bitcoin ETF (exchange-traded fund), causing Grayscale shares to trade at a premium over the price of Bitcoin. Outside BTC and ETH, Grayscale also offers XRP, XLM, LTC, BCH, XLM, ZEC, and others.
