A falling DASH/XBT or DASH/USD is an indicator that anyone who is short Monero would be wise to pay attention to. Just look for example at what happened in August 2016. First Dash falls then Monero rises. Theoretically one can make a case that the Monero markets are un-correlated to the Dash markets; however there is still a significant amount of emotion on the subject in both the Monero and Dash communities for short term leveraged traders to ignore.
