Portfolio company Tradeblock has publicly launched its index for Ethereum Classic, which will also be used as the reference rate for the Grayscale's Ethereum Investment Trust.
The sustained economic growth of bitcoin has been a catalyst for an increasing interest in the broader digital currency market. Once a market filled with a multitude of novel yet unproven offerings, digital currencies are now maturing into a market with established leaders that attracts the interest of casual and professional investors alike. Increasingly, these markets are being used by the public to store value, transfer value, profit on their volatility and to diversify portfolios. They also act as havens for the ongoing debates regarding the governance and technological aspects of the various technical protocols.
