I hope the buyer knows what he is doing.
I don't, but that's the nature of gambling, and I can afford to lose it all.
You wont lose it all no matter what, but even a gambler likes to know the odds and if you were not being ironical about not knowing what you are doing, then I hope at least you have a gpumax account; if you dont, sign up for one asap (or perhaps ask giga to make a deal so you can use his). This contract is risky but not entirely unreasonable for someone who knows what he is doing and wants to pool hop and expects >130% PPS. If you are going to direct these hashes to a regular pool at 100% PPS, chances of you making a profit are IMO, almost nill. Next difficulty change is in 4 days, currently estimated at +17%http://dot-bit.org/tools/nextDifficulty.php
7 more difficulty changes to come. Can you spot the trend:http://bitcoin.sipa.be/speed-lin.png
I did not say I was a complete idiot.
What I was trying to get across was that I'm not able to predict the difficulty. I can only make an educated guess, and so can you.
Thanks for the tip re: GPUMAX, but I'm already mining there.
