Hi Ian
That is a huge investment

I hope all goes well for you.
I'm holding some satoshi's to invest in some ghs of S7, what are your thoughts on it?
I have a question regarding hashnest if you may... Its regarding there graphic
The serpent like line, before it was most of the time on about 0.01, now days its lower than 0.008.
What does this mean? That mining is becoming less and less profitable correct? And this values going down is because of the difficulty increase?
Thanks in advance.
PS: Still getting exactly the same value per ghs from genesis has you.

S7 will be quite good as the maintenance fee is pretty low but I think at first when hashpower is being sold on the marketplace it will be quite expensive compared to S5 hash but in the future when difficulty increases and then the blockhalving happens in July, the S7 should be pretty good because of the fact its really power efficient.
Regarding hashnest, well I have been reading posts about pool performance lately, some users have been banned and also any threads posted about the pool seem to get deleted so something is going on anyway. Some users have their own theories about it which I will not go on about here as they can be found on other threads in this forum.
Personally I think something is up as the payouts with Hashnest have been a little inconsistent lately, not sure why..but I hope they get their issues fixed soon whatever they are.
