I have had someone rent most of my rigs for about a week now. Their pool is always going up and down and most always under hashing. What ever the customer is mining must be worth it as he keeps renewing the rigs.
What happens when I'm forced to upgrade on July 4th? Will the lease get cancelled and refunded every time it shows rig down? That would suck because the rig is fine, it's the pool. The customer knows this and is happy the way it is.
I'm picturing loosing a bunch of rental time and the customer getting frustrated by having to start the lease all over again. Maybe next time he'll choose someone else's rig...
The solution is very simple. Simply add a backup pool.
