This could just be what BTC needs, a negative correlation, where as BTC rises, ETH falls and capital moves back to BTC. GL trading, don't hodl too hard.
I wanted to use the new poloniex data, as it is where most of the volume on ETH is, luckily the new chart is no different form the old chart.
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.
The correlation indicator here flips back and forth, showing in my opinion that the two are independent of each other.
This was just a check, this makes perfect sense and was expected.
