while the power deal I have certainly earns some profit for me.
So today for me this is a power game not a gear game.
there is no bleeding edge gear for me to buy from someone I trust and believe in
So that all works for you (which is cool). But where I am, with my setup, there's no way on earth I can make any power deal that will pay off in less than 20 years (and chuck knows where I'll be in 20 years' time).
The only gear that *could* make sense to buy currently are FPGAs and - as you basically said - that's still a gamble.
I've changed my power company as the previous one was about to increase electricity costs by something like 40%. The new company now just announced they'd have to increase the kW.h rate as well...

So there's no escape. Only managing as well as I can.
right 100% agreement on making do .
I am at a 500 usd certain profit for June 2018
Vs an 11,000 profit in December 2017.
Kast year was a banner year for me and many others.
there is a constant flux in the game
power is king---gear is king---power is king...gear is king so on and so forth.
Since I have 11 ldle l3+ and 2 s9i shipping to me today my need for gear = 0
Will I buy the acorn yeah I will get 1 or 2 or 3.
Now when I look at solar like the Pay One Price or pop idea buysolar and I are doing I think of it as all mining gear.
If I make a 1500 watt setup and toss in an s9i total cost of 1700 for solar + s9i .
the roi works like this an s9i cost earn 4 a day there is no more cost for the 1700 assuming nothing breaks.
4 bucks a day 425 days and gear = paid off.
if the s9i dies put in another and the 1700 goes to 2400/4 = 600 days.
since the power part is paid upfront I consider it as part of the sunk cost.
In theory the panels will last 20 years.
I may need 1 extra inverter I may need I extra s9i.
It is a risk as to durability of gear. The s9i and the invertor may need replacement.To me FPGA's = loser in the long run. Short term they can be good.
I know a lot about chasing mining gear since I have mined nonstop since 2012.
You can not make constant profit with mining gear unless you have a power angle = fact. In fact it is the basis of Pow coins turn power into coins.
