The document summarizes the Bitcoin Investment Trust (BIT), which is a private investment vehicle that solely invests in bitcoin. It allows investors to gain exposure to bitcoin prices without having to buy, store, or safekeep bitcoins directly. The BIT addresses issues like dealing with unregulated bitcoin sources, illiquid bitcoin markets, unclear title and auditing of bitcoin holdings, and challenges storing bitcoin safely. It provides exposure to bitcoin through a security that can be held in traditional investment accounts. As of December 2014, the BIT held over 134,000 bitcoin worth around $50.9 million and was administered by Grayscale Investments and its affiliates.
