your point on ICO's maybe correct but for me for the existing coins, i believe this is a very good time to buy. All of them are in a very low price if you can manage to secure more of them in a very low price what you can do is to hold and secure a big volume of quantity of potential coins. You must consider the time span if you will be waiting till september. For me it's not a big deal to endure paper losses that succeeding month as long as you can wait when the prices are on up trend.
