You are right. Some short time investors will dump it early in Poloniex. Maybe wait until the air is clear and start buying when a bit lower but it's hard to identify early how much its stable value.
Look at the amount of ZEC put for sale on Poloniex. You'll be able to observe the more it is higher the price is.
The more it is the higher the price is? You know this doesn't make any sense. The price is 100% down and will crash much lower than 0.5BTC. Just wait a few days/weeks
