Sorry my magic crystal ball only sees 5 days in to the future..

What makes you think the difficulty is going to suddenly slow down?

Especially after this:

Historical Difficulty Increase
30 Day 47 %
60 Day 96 %
90 Day 183 %

Are you really willing to gamble 10btc on something that may or may not happen but entirely could?

Are you assuming that the 30PH/month from spondoolies is the only hardware that will be added to the network after august?
