I should mention that I am currently paid in ETH so I ignore the BTC chart beyond looking at the longs and shorts to get an idea of how much pressure BTC is placing on ETH.
This just gives me an idea if BTC is going to gain momentum or not. Which does change my strategy a bit but for the most part I still am neutral, so it doesn't really affect me much.
I also have no real use for BTC because the network is so slow and expensive. So I have a much smaller amount of BTC until there is a real use case built on the BTC network beyond speculation and ideologically driven payments and savings.
If I can't actively use a technology I tend to not hang onto it. I have a similar stock investment strategy where I only buy what I personally use and understand.
