Digital Assets: S&P Cryptocurrency Index Series
- What is the S&P Cryptocurrency Index Series? The S&P Cryptocurrency Index Series is part of S&P DJI’s Digital Assets indices and is designed to measure the spot-based performance of a selection of cryptocurrencies, also referred to as “coins” in this document, that meet minimum liquidity and market capitalization criteria and are listed on trading facilities (referred to within this document as “exchanges”) included among the primary markets covered by the Lukka Prime data product published by Lukka, Inc.
