While this article makes great points, you are suggesting that you know the future price of the coin and future demand (which you are implying is lower than now). You have no way of knowing this as a fact. You should be presenting your info as a potential issue and not an absolute. Your title is also very over-dramatic... perhaps: "Somethings to consider before investing in Ember" would be a more rational and logical title.
