I could be wrong...but....
Alts went down everywhere when Bitcoin bubbled over $500. People dump Alts and get into BTC. Funny thing is the decline didn't impact Hyper significantly for more than a day. LTC, the so-called "silver" of alt coins continues to decline. Bittrex had alts in free fall during the BTC bubble. I'm still holding losses watching the market cool down but I'm not worried at all. This is very temporary for HYPER. It's been ranging 1750 to 2400 for a while. Pretty damn good for a coin this old. Maybe I'm wrong but I love it anyway.
but why selling if btc is rising, i dont get those who are selling....but its their decision..
