The price of ZCash might go to $20. But it will not go to $10. The price lowest we can buy is around $15.
it is dump and dump always leads to a massive decline and with Zcash since there is no real interest in it and miners are mining a lot of coin each day on the market the buy support can not handle it and it goes down.
p.s. @OP start one topic about Zcash and continue discussion there. you are just crowding this board with the same topic. there is no reason for creating a new one when a similar topic exists.
