I expect it will be ZCash and Iconomi after their adding to exchange.
Indeed maybe Zcash will than rise up but we cannot predict this, I have a feeling it will after monero but we will see what is gonna happen soon.
Yeah. This the rise of Zcash might happen as it will be "hyped" in its first days. I usually participate in ICO's and wait for the price to increase in an specific coin to sell and make profit, but it seems that Zcash will not have an ICO so the only way would be to buy at exchanges among its first day of launch in order to profit later in the future.
It will be very interesting to see what will happen with both ZCash and Monero once ZCash comes live.
