Price already going down before mintpal listing lol. Maybe dev is waiting for speculators to sell out before announcing some news, but otherwise I can see the price tank pretty hard. No wonder people are not voting for coinpayments. No community feeling anymore because of the lack of transparency.
No. The price fell because some one sold a load of coins between 7100/8100 it was just an attempt to trigger panic selling. Which didn't happen.
I have seen it happening, small sell orders from +-140 coins were then trying to make people sell into the buy orders at 7100 level. Which again didn't happen.
