You should not even compare Hashnest with Genesis Mining in the first place. Why? Because if you buy (imaginative figures) 10 THS in Genesis , then your money is stuck with them, and maybe they shut down your miner after 2-3 months saying its not anymore profitable, guess what you lost big. Different with Hashnest where you can trade your mining power.
But what I understand from Hashnest that even the Hash you can buy and sell has already a fix maintaince fee.
That is the reason why some Hash-offers are cheaper comparing to other offers per Hash.
No offer on Hashnest sold from a customer would ever give me ROI.
Only if the btc price would rise (but in this case I just can invest in bitcoins, too)
or
if the new asic chips from newcomer to b2c market coming soon will flop and bitmain has not the need of release their 16/14/12/10nm - then the bitcoin split will lift up the bitcoin chart and nothing will happen.
I think it was bitfury annoucing to send the 16nm chips to retailer since march 2016.
And who was the 14nm company? (forgot it - was another mining farm company with ideads of an own asic chip - have to look up my 1000 favorite bookmarks)
Anyways, they just said more information will follow soon on 14nm.
16nm seems to be out to system builders, retailers, engieneer ... , but we will see if a b2c machine will follow.
The retailers can sell to the public, but they dont have to and can use the advantage first to themselves, then to other business partner with high invests and then to all - at the end
If those two will fail for private customer market and no one else I didnt see or forgot at this point will open up with a new chip I didnt see the need of bitmain to release somethink more effective out of the desk
In this case my own S7 will stay positive and a mining offer will stay good, too. Does not matter if Genesis in Iceland or Antpool @China.
If not and hash power will loose effectivity, both ways are no longer nice and you have to invest in new hardware or hashpower, because of a contract end.
6cent of power cost is nice @Genesis
My are 0.00 - limited - but enough free power left
I decided to invest in own GPU-machines for some Scrypt, Scrpt-N, Quark or whatever - or some more ASIC for SHA256(d) - I will see.
First I will await ...
... 1) new asics and tests about them. I am not in a hurry and I am fine with batch #3 or higher
... 2) the bitcoin split
I think its time to relax and wait a little bit. Bitcoin is climbing already, slow, but up, up, up, down, up, up => up
And how the market really will change - no one can say 100%. Its bitcoin :p
