I notice recently many customer want to sell s5, so i provide a buy back option now at the price of 350$, let me know if you want to use this option, this price has included the pre-paid host fee to 20th Sep.
The price will be kept for 3 days, then i will be adjusted according to how much i can sell the miner on china used miner market.
I donot want customer's miner suddenly become worthless like many customer who have s2 miner in hashnest plat currently experienced.., so let me know if you want use this option.

How to process: if anyone want to use this option, you need do the following things

1:make sure you have paid the host fee to 20th Sep
2:send me a PM and list how much unit you want to sell back to me
3:list your btc address to receive money, the price is 350$ for each unit s5

I will send btc directly according to real time exchange ratio on 5th sep to all the customer who want to use this option, then switch the miner to me.
