every week for the past month, btc value has been falling by $10US, and extrapolating it to the next few weeks gives me the following;
July 10 -- $70
July 17 -- $60
July 24 -- $50
,

,
August 21 -- $10
Once the $10 firewall is breeched, the race to $2 will happen in a few days.
Thus, by the end of August 2013, it will be $2 or less.
