The correlation indicator here flips back and forth, showing in my opinion that the two are independent of each other.
Comment: positive flip didn't last long, will it become a negative correlation bias over time? The community sure thinks so, and might be self-fulfilling.
Agreed, need a bigger sample size to see how the relationship will be ultimately, but that is interesting thus far. Pretty much all alts(to this point) have been assets of the same class as bitcoin, and have moved together with it (albeit at different rates thus changes in the ratios of their price to btc's). So, if ETH maintains it's independence it would be a first.
