The solar has a 20-30 year life span.
With New Jersey rules and incentives it will pay off in 3-5 years.
So at worst 15 years to 20 years of viable paid off energy.
Even with the free electricity, we're still sinking costs into the ASICs (and also opportunity cost if you're also trading). I don't have solar, but I do have very cheap Electricity Phil. Even I have to admit, By the time my new machines ROI, the people who bought BTC@7k will probably be 5x richer from the same amount of money lol
it is why I have drifted away from asics towards gpus
I still have 30k in gpu gear.
and I have under 10k in asics. I have 1 two board s-9 buysolar has 3 or 4 s-9s
I don't trade as I don't gamble/speculate.
With the set power cost deal I have I will always profit as long as I don't go far past the arrays power cap.
So a gpu with a 3 year warranty not pushed will last the 3 years and always earn over power cost.
Of course my earnings may not hit 15k a month like in dec .
I am 1181 all mine 1181
and 187 50-50 93
and 2566 50-50 1283
total = 2557 after all costs
and I left out 2 board s-9 on 50-50 that is 0.02385 btc 50 -50 a month about 90 more
so 2656 usd a month net.
When buysolar found me and showed me his plan for the array I realized I could get rid of one risk in mining that is power.
We started out with avalons and s-7s and gear broke a lot. S-7's and psu's more so then avalon.
after study of cost factors. I realized we could shift towards gpu mining and get rid of gear breaking issues.
Then gpus took off last year. So I do lots of cost risk projections and gpus are almost always better due to solid warranty. Plus fans break more then any other thing and that is a cheap fix.
I like the idea of a better asic like this dragonmint but right now at 16th and 1200 watts
my deal would be 8000 th and 0 power so in a year it earns 2000 usd
that creates a risk for me if it breaks
for a guy like you in a year at 4 cent power it nets 3600.
I used 8000 a coin with flat diff we both know diff won't be flat and price is ?
I imagined price rise to equal diff rise. so the asic for you is less risky then for me. mostly due to my power deal.
Buysolar tends to have a few extra asics all to himself on the array . While our shared miners are the gpus which I own completely.
I hesitated to buy here at first due to preorder wait which kills me math wise.
