That's a good speculation for this month of September. Though I'm not sure about reaching $8,400 this soon. Maybe we'll be seeing between 5500 and not higher than 6000. I guess major increase will be happening after November. And since most people will have higher income and bonuses during November and December I guess there are people who have it in their mind to save some of it for btc investment. Which in turn will result to a massive value increase.
