I've been mining on my AMD 290x for the past few days - I brought it for gaming, so I don't need to get a return on the hardware, and the heat generated is useful too - it keeps my apartment a little warmer. Looking at a profit of around $8 per day at current difficulty, which is a pretty cheap heating solution!

I just bought 3 290x cards for this purpose. Right now they pay for themselves in 2 months.

I'm currently doing this right now with 30 instances. I'm currently operating at about 7 MH/s. At current rates, it's not exactly "profitable", but I'm using up some AWS credit that I have. I don't intend to sell the LTC until it hits about 40 or maybe 50, but in any case, it's still all profit for me, other than the fact that I lose out on the AWS credit for other uses. Edit: I'm also not paying $6/hr... That would…

Everyone is using $100 ec2 credits for coin mining, that's why everyone is overpaying for spot price at the moment

I have much more than $100. Hence why I'm even bothering.

It's certainly more risky when you are buying hardware only to mine - although I guess that is bounded by the fact that even if FPGA or ASIC miners were to make it unprofitable, the GPUs are still valuable and you can sell them.

Do you mine on linux with cgminer? I'm having terrible reliability issues. I have to restart cgminer every hour or else it crashes. Even with this measure, it crashed yesterday night and I sadly lost mining time :)

Why not write a script to get called by cron to check up on things?

I love the double standards on display at HN. In this whole thread, not a single mention of the opportunity cost of smart people wasting resources on things not productive to society or how it is an unfair market because someone is taking advantage of the other participants by being more sophisticated than them.

What would the discussion be like if the headline was "Briefly profitable HFT FX trading through better code"?

"I" meant "cron". The system does this on its own, but it's still a cheap hack. I'd like the crashes to be more predictable, but maybe this is the best I'll ever do. I've spent enough time setting this up already, other things to do!

You speak as though the process of continually training/learning is not valuable to society. This is someone spending their free time learning optimization. You wouldn't criticize them if they wrote "I practiced code optimization methods in a Coursera class." This is someone's free time.

I don't spend 24/7 attempting to make your life better.

Thanks for the fun! And thanks to my online-and-offline friends who put up with me babbling about bitcoin entirely too much recently. I'm done. I think. :-)

I'd been doing my own research on viability of mining on Amazon, and I posed a question on the AWS forums asking how it's possible the spot prices could be going so high. There's instances going anywhere from 5-20 times their On-Demand prices. At this time, no one's answered it, so if anyone here knows, I'd love to hear why someone would pay $10.00 per hour for an instance they can get On-Demand for $2.40.

It's possible that someone has found a way to speed up scrypt. We could solve for a lower bound on what that speedup must be.
