Well, we providers are not a cartel taking turns with renters. My tactic is to keep three rigs continuously rented and build a long term relationship with my renter, who does all the work of finding coins to mine.

I know that I will have to migrate my GPU rigs over to Scrypt-N because of Scrypt-ASICs now and coming. I await the presence of offers, i.e. bids, on the Scrypt-N side.
