You mean individual coin market cap vs total market cap?
Exactly that is what I mean! I have only found correlation measurements between two coins! But no sites that would measure correlation with an index. For example here is a list of indexes I compiled: https[Suspicious link removed]s_tracking_cryptocurrencies - now I would like to know how much one coin correlates with one of this indexes. You are for sure right, that correlation is positive but it would be interesting to see how strong is the correlation for each individual coin I have invested (e.g. NEO, ETH, Nano, etc) with the index and not only with BTC
