FTSE plans to roll out the crypto index in December this year and has announced that it will be covering 43 digital assets.While there were very few till 2021 when it comes to crypto, indices have been used to track some particular areas of the stock market throughout its history.A total of eight indices are part of this new series, including four indices that combine coins of more than one market cap size, as well as one each for micro-cap coins, small-cap coins, mid-cap coins, and large-cap coins. The new indices are based on the standard set of 21 criteria to determine which institutions can be trusted to provide accurate pricing data, according to FTSE Russell's website. Once decided by monitoring data from hundreds of exchanges, these institutions' price data will be used to determine which coin goes in which index and to determine the net performance of the index.Arne Staal, CEO at FTSE Russell, argued in a press release that the new FTSE Global Digital Asset Index Series would bring transparency to the crypto market. He said, "FTSE Russell has taken a measured approach to this frontier investment space and has built a rigorous and transparent framework, underpinned by robust governance and comprehensive data to meet investor needs, both where they are now and as they prepare for change in this market."Shashank is founder at yMedia.
