Li - you've mentioned a few times that you may be able to get hosting costs down - any progress on that front?
Edit: Or maybe make the PSU a part of the hosting fee? In that case you would own the PSU, which makes more sense because they're not very cost-effective to ship outside of China, but would retain their resale value for you.
Sorry, the stability of the farm who offer cheap price canot meet my requirement, they can only promise 90% uptime, which is unacceptable. so no plan to down the host fee now.
As for psu, it is a big money even for me, canot offer it for free, will sell it together with miner on two-hand market and refund the money to customer as usual.
