I was just going to reply the same thing.

OP: the simple fact that you're having your doubts about the fact that it is or isn't worth it shows to me that:

-You haven't made a real analysis about your mining project in terms of ROI and what it's really going to cost you (electricity, time, maintenance etc.)
-Your investing a lot of money you're unsure of getting back. My pinky says your 10K is a lot of money for you

Personally, I think it's not smart to just drop 10K in something you seem to have little experience with. Start small and grow.

And when I talk about electricity, it's not just the cost per kWh, I'm also talking about having a secure installation. 10K will buy you quite a few rigs that will pull quite some Amps. I have no clue where you're planning on storing your mining operation, but you should make sure the electrical installation is top notch and can support a lot of Amps.

That said, it's your money, do what you want with it....
