If we climb above $400 again the sells walls will pile on so fast...
It has already! $409 and climbing now 
Where did you get the $409 number? I see the price is still around $330. Is that a typo?
The price shall not reach $500 in November. In December it is still possible, if there is a year end rally like the conventional stock rally each year.
A end year rally is logic if you take in account where we come from. Maybe 400 usd at best
Not sure why but i also feel that 280 is also possible
