The cheapest way to buy S9s is to buy from Bitmain's CN interface - 13TH model PSU included currently sells at RMB11100 and if you are a secondtime customer, they give you RMB 200 coupon.
If you mine in China, the shipping cost is well within USD 35 and you can expect them to arrive in about a week after payment confirmed.
The trick is that you can't ship the miner to your home country easily without paying too much - that is exactly what
SinoHash expect to solve - We are offering USD0.045 per kWh hosting fee (this is all you need to pay and you pay at the end of the first month; no hidden fees). The price is prob cheaper than the electricity you pay in your country, not to mention removing the need to do proper cooling, network, security and deal with the noise.
Thanks.
A few questions;
1. web site says that you don't sell the miner to me even if i pay $1700 upfront for S9. I understand that technically you simply transfer the ownership of miner that you got from Bitmain/Avalon or place an order in lieu of customers order, but in the west it is considered selling and/or being a reseller. Nothing is wrong with that as long as you maintain the record that customer OWNS the miner. I would clarify this page:
https://sinohash.com/collections/miner-models/products/bitmain-s92. Sinohash only promises to help cutsomers sell their miner on the seconhand market at the BEST available price. Two comments: how this best available price is/will be established? I say it should be be ebay instead of some underbidding internal dealer. Second, why no provision of sending miner to the owner or a third party? It might still be cost-effective.
3. if cost is RMB 11100, why the charge is $1700 instead of $1607? A small detail, but explaining helps understanding.
TL;DR Very good hosting price, high miner price (about $200 higher than latest Bitmain sale including shipping to US), not clear re ownership record, not clear re sending miner to owner, not clear re secondhand price to sell.
