We can't be sure that Ethereum will trade at $200 this month. I believe that this requires the growth of Bitcoin and the cryptocurrency market, but there is no reason for this. The launch of Bukkit was postponed again, which means that in January we should not hope for the growth of the market and Ethereum in particular.
I think that because of the update, Ethereum will be able to get close to $ 200, but then it will fall again.
