ZCASH (ZEC) has just been added to Bithumb a very big exchange in South Korea. When Bitcoin Cash, Monero and Litecoin were added in that same exchange, they shot off three times their values. There was just premature buying last week that caused ZEC price to surge. Two days before ZEC actually activated for trading in Bithumb, an employee told everyone he knew, got his friends excited, they bought in, price ramped up but the Korean public couldn't buy in because they could only buy in at October 1, so that stopped what would've been a huge run up.
I think people bidding to buy are just trying to get a good price and 'weak hands' keep giving in out of fear. ZEC will creep back up. Why shouldn't it? It's still as good a project as it's ever been. In fact Edward Snowden tweeted that it is probably the most secure, privacy-centric coin there is at the moment. And when people, especially the Koreans, begin to see it, they will buy in and accelerate the price to go up. If it's just as good as last few times, we can expect the price to rise at least three times, in, around or hopefully above the $800 - $900 range.
So I say get in quick if you're not in already, get these good prices now and wait for the ride.
I'm wildly speculating here, of course. I'm happy to hear what the rest thinks.
