This article mentions one of several metrics we offer regarding top holders addresses. Please check this article for an introduction on 'Top Holders' and the complete list of metrics offered.
This graph shows the relative amount of tokens held by all the top holders compared to the total amount of tokens in existence, as well as the asset's price.
As you can see, we also display the top holder's share of the total supply split by exchange- and non-exchange wallets.
The amount of top holders addresses included in the calculation can be chosen at the top by selecting 'HoldersCount'. The HoldersCount in the above screenshot of BAT's top holders percentage of total supply is set to 50.
The assets's price can be displayed in USD or BTC, which can be selected through the 'Currency' field at the top.
