    We have removed the 25% cap on any single asset in our currency sector. There is no longer any limit to the maximum weight an asset may have in the currency index. The platform and application indexes remain unchanged with the 25% cap in place.

    We are switching our source for the market capitilzation, and float percentages, of crypto assets from coinmarketcap.com to onchainfx.com. This is in accordance with our view that the typical market caps the community has been using are flawed, and a switch to fully diluted market cap is necessary. We applaud onchainfx for rising to fill that need.

    This change will result primarily in zcash and stellar lumens being in the ten index. It will also make ethereum classic, maidsafecoin, and gnosis much higher on the selection list than before. Weightings will be relatively unaffected, as the publicly available supply is consistent between the two sources.

    Additionally, we are adding a new rule to our general methodology. We are adding a float percentage requirement (or % available supply) of 10% to prevent the inclusion of assets that are extremely centralized. This requirement currently only excludes NEO GAS.

    Also starting with the October rebalance we will no longer be updating the tables in the methodology section with the weightings at each rebalance. You can instead find a link to those on our updates page. We will leave the tables up to help provide historical context.


    The September Rebalance will be effective as of 9/20/2017 and index membership changes are confirmed. Please see the tables in the methodology section for member weightings after the rebalance.
