It's because most coins prices fall down and consider to crash.
Then, it's cause most mining pools, miners, and cloud mining run into loss, simply because mining hardware still expensive but the profits which generated bitcoin has declined. For people who invest in genesis mining, just wait if they can find a gate to get out from this situation, but for new investors it's a loss because they have to wait for 5-6 months for ROI. Too early to judge I guess, but hopefully genesis mining will pay everyone.
