Re: ANN: BITMAIN has Tested Its 28nm Bitcoin Mining Chip BM1382
http://www.spondoolies-tech.com/products/sp30-yukon-september-batch-1 @ just over $5000 this really is quite a crap deal when you can get 12 S3's now without the wait for just over $5500. Just under double the power to power the S3's but between now and September the diff increase will soon sort out that benefit that the SP30 has. Plus I would guess by September the price on the S3 will be down as low as 0.5BTC.
Bitmain still are by far the best out their for price, even though ROI is highly unlikely for those who don't resell their rigs frequently.
(Or if your like me and have a free scheme offering solar panels for free, the supplier just keeps any excess energy produced and sells it back to the grid - No excess energy in this house

)Well you need a lot of psu's to run 12 s'3.
Lets say you get 12 for 8.88 btc or 5683.20 usd.
you need 5 evga psu's that is about 900 . you are at 6583.
your gear does not show until JULY 22..
It hashes at 6th pulling 5000 watts. it earns 3k and then it is sept 24.
this is with 20% and 630 usd a coin.
but use 17% and 700 a coin
it is at 3.8k
15% and 750 a coin = 4.5k
so I am thinking while the s-3 is better then the sp30 it will be hard pushed to make money.
As I said ROI on the S3 is still unlikely under normal circumstances. But Bitmain seem to be the only ones who get close to the mark. Spondoolies are probably the next best contender, the SP10 for a little while was a good deal and i should make ROI just about.
Basically mining is not going to make any one a fortune these days unless you have big money to start with. But its a more fun way to get bitcoin and if done correctly it is slightly more profitable then just buying bitcoin. From my calculations I would say I am about 4.5 BTC better of over the last 6 months from mining then if I had just brought bitcoin flat out. So its still worth it for the little attention I have to apply to it, but even if I was working on a loss I would still be dabbling in mining for the fun of it.
