The 17th of November is an important day for lisk. The number of coins received per block solved is reduced from 5 to 4- this by definition reduces the supply of coins and increases the price. In addition, the next 2-3 months the rebrand and the SDK are both expected to happen which will significantly increase the value of Lisk.

There will be short term volatility with this coin, but it is all heading in an upwards direction for the long term. $10-$15 could easily be the price at the end of 2017 or start of 2018. I agree now would be a good time to get in, it probably won't be any cheaper than this price, especially after the 17th.
