I only rent 72 hour terms and usually at a price that assures immediate rental. All three of my rigs have more than  1000 hours rented. After an hour un-rented, I accept the highest offer for 72 hours.

I believe GPU mining is a shared business between myself and my renters. They do all the work of finding coins to mine and taking the risk of holding or exchanging altcoins. My rigs are stable and work fine if I do not touch them. I operate headless Ubuntu Linux, with cgmon software to restart cgminer or the rig in the rare case of a sick GPU. I do not use LRP nor any other advanced feature of LeaseRig, because stability for my customer is the most important aspect of what I do.

I never hear from my customers and have in those rare cases of an outage, cheefully doubled the lost time on the lease.

I would not use a pool directly even if I could make more coins because I am paid in advance by LeaseRig in bitcoin. With a pool there is some uncertainty as to results and payment.

I am your competition - and the customers' friend.
