(and not just leasing computers for general purposes that have AMD GPUs...which would lease for 1/10th the rates you're asking, by the way)
Please direct everyone to a place that offers 1.2 Ghash for $75 per 30 day lease. I would gladly lease that.
Nobody leases hash rates. They lease equipment. Typical lease rates are around 1/10th-1/12th of the purchase price, per month, with a multi-year agreement.
Well, so then I must have been on a different forum where a couple of guys offered exactly this: leasing hash rates, a.k.a. mining contracts. Actually it's because it makes a lot sense not just for the seller but for the buyer as well. Personally I started setting up such a service as well
and I don't see a problem in offering such thing. It's (almost) just a matter of the right price, no? And trust of course.
