OK, thanks for the help guys. I assumed a new model would arrive soon.
To hasnest:
On your order page for buying the s5, it lists a maintenance fee by the machine. However when you read down below it says that there are no maintenance fees, but there is an electricity cost. I assume that the cost of electricity is what you mean by the maintenance fee, but its confusing. Also much of your site is translated poorly into English. It gives your site an unprofessional feel that makes me a little nervous. You have a great reputation and I am not saying anything fishy is going on, but it may look like a scam site to a casual observer due to the poor translation.
Also Always do a quick check of the market price for s5 vs the shop price of s5 per gh.
You will wait up to 72 hours if you buy from the shop for your ghs to be credited to your account vs getting it right away on the market.
However, sometimes it is much better to buy on the market and sometimes much better to buy from the shop as people don't understand the 2 options.
To get the shop price of per gh just take the bitcoin price ( they have listed, and yes it changes with changes in the usd/btc price... if usd/btc price goes down they charge more btc to equate to 390 usd and visa versa ) and divide by how many gh an s5 unit gives ( 1155 gh )
For example at this very moment the hashnest shop price 1.64 btc per s5 divided by 1155 gh gives a per gh price of .00141 which is much cheaper then the market atm. In my opinion it is enough of a difference that it is probably better to buy from the shop at the moment then on the overpriced open market.
Remember though btc/usd changes fast and you will wait 72 hours to get your account credited 1155 gh per s5 unit bought. Then again it could go the other way as well and you will have got an even better deal should the btc usd price go lower.
That is why when btc/usd prices go up the amount of btc you pay for s5 unit goes down ( gets cheaper ) and the market tends to drop. On the reverse if btc/usd goes down then the units cost more btc to equal 390 usd and the s5 open market tends to go up.
The point is take advantage of when the people who don't understand what they own and how everything works are paying too much or the open market has a deal compared to the shop. It is especially nice when the open market price is cheaper then the shop price because you are getting a discount to what the market should be at and you are getting your ghs immediately.
Anyways, good luck...
