Grayscale Investments, the company behind the Bitcoin Investment Trust (OTC: GBTC), announced Tuesday that it had opened four new investment products that provide investors with exposure to cryptocurrencies in a more familiar wrapper. Like Grayscale’s other products, these new trusts will be offered in a private placement to accredited investors who purchase a minimum of $10,000 worth of shares and submit to a one-year vesting period. Eventually, the trust sponsor will likely seek to list these shares on publicly-quoted over-the-counter (OTC) platforms, as it already has with the Bitcoin Investment Trust. Once shares are publicly-quoted, they have more liquidity and can also be purchased through retail brokerage accounts — though often at a steep premium over the value of the underlying assets. Though anathema to many financial analysts due to its heavy premium on the secondary market, the Bitcoin Investment Trust has proven to be extremely popular among both buyers who are nervous to hold cryptoassets directly and investors who desire to gain exposure to Bitcoin through tax-advantaged retirement accounts.
