I used two dates. The first date is August 7, 2014 and 5 coins were used, the second date is January 1, 2015 and 6 coins were used.
The green line corresponds to the first date and the blue line corresponds to the second date. Thus, we obtain two variants of the crypto index.
With this crypto index ( abbreviated name-KRIN), you can observe the aggregate price movement of the crypto community.
