CoinDesk Indices, a subsidiary of CoinDesk, introduced the CoinDesk20 index on Wednesday. The CoinDesk 20 is a broad crypto market benchmark, representing over 90% of the total value. While bitcoin and ether (ETH) account for just over 50% of the index, other tokens like filecoin (FIL), stellar’s XLM, aptos’ APT, XRP, dogecoin (DOGE), and others make for the rest, making it an S&P 500-like gauge.
