why lisk is going down...?
OMG...
With no apparent negative news, but no positive news either, its just the market playing with the price. If you hold a lot of LSK, then I suggest that you don't look the market price for you not to get panicked.

And you can add the DAO hack, the ETH price and the launch of WAVES on Bittrex. BTC volume is just switching between altcoins and playing with the whales.
