So at $13,000 a year with 7 gpus then subtract what everything cost up front (case, cards, etc) and you are left with about $1.34 LOL
Exaggerating a little bit but unless you have stuff laying around to use, it seems like a huge gamble to spend this much money (and if you have that much money laying around, what do you need to do this for anyway?) for a small return. No, $13,000 is not small but after taxes (yes, legally you should be paying taxes from what I have red -
https://www.reddit.com/r/Bitcoin/commen ... rs_to_the/ - for example) you will be around $10,000. So minus the $2500(ish) of your initial investment and your profit drops to $7500. Still it is not an amount to sneeze at but there are a lot of ifs/maybes/hopefullys involved so i like how you said
(Please keep in mind the price of etherum could always drop to zero or skyrocket, so think long and hard before you buy hardware to do this.)
. PSSSSTTTTTTTT - ethereum is spelled wrong btw
I would give it a try if I have the money just laying around, I mean, why not, but I don't have that kind of cash (sure I could charge it but then you have to look at your interest rates, etc) just hanging around.
Are you going to let this run? Would be great to see how everything goes with running it 24/7/365! If there are no break downs or problems then the value skyrockets. Plus to get an exact amount of money made. Even if you are not allowed to keep the money (donated cards, loaners, whatever would prohibit it) you could always donate it to charity.
Are video cards covered under warranty for continuous 24/7 use? Hmmm...never thought about that. bet they will put an exclusion in the warranty if there isn't one already, if they see a lot of warranty repairs.
