I'm having a hard time with this...
I certainly WANT to buy up a number of these...I even was ready to pull the trigger on another rack at my co-lo here for the hosting.
But running the numbers I'm having 0 luck making it make sense...
I'm seeing positive returns die after 4 months, with maybe 60-70% of the initial cost being recouped (after electricity costs) before they would need to be shut down. Even if I ran them at home with a slightly lower hosting cost it's a no-go.
Is anyone able to pull together numbers that make sense? Or are we rushing to buy these because we want new toys?
And remember...the argument of buying them in the hopes of BTC skyrocketing just means you may as well spend your money on more coins, or holding the ones you have...
Start mining as soon as you get the S3, and keep tabs on what they are selling for around the web... From my experience, mining for 50%-75% of the miners life on full tilt or OC'd if possible gives you enough coin (barring no crazy drops in value) that you can then sell the miner for some profit.. I have done this with a few 1TH+ machines and it has yet to fail. I'm hoping the same is true with smaller power, more in demand antminers..
Edit: this is my first time buying new, so it might not work out. In the past i've bought used, mined for a few weeks then flipped for the same price i paid on ebay. They pay crazy prices over there, just factor in ebay and paypal fees.
This is pretty much my strategy with all ASICs. If you want until it doesn't even pay for it's electricity anymore, NOTHING is gonna ROI. Give your S3 a good home for a few months while the hashrate it offers is somewhat respectable, then sell it at an inflated price to some dummy on ebay who doesn't realize it is nearly obsolete hardware. If you wait until it isn't paying for it's own electricity anymore, the market is flooded with them. Gotta beat the other miners to the 2nd hand market. Kinda takes a long time to see any sort of return and it's not much, but it gives me a new toy to play with for a few months and earns me a few hundred bucks or a fraction of a BTC in the end, so what the hell.
Of course this is tough to do if your goal is investing big in hardware. I'm just a small time miner, it'll be easy for me to sell off my 2 S3's in a few months. Now if you had hundreds of them.....yeah it's a pretty bad investment.
