Dude, you are literally printing money with the the starting bid of 230 BTC. Good luck!

One of the rare opportunities to start ASIC-mining right away with a considerable hashing power: https://bitcointalk.org/index.php?topic=221806.0

I will accept offers by pm if you're not able to post in the auction thread.

damns 250btc, 80 days ROI with current difficulty, making it end of August starting to mine for profit, there will be very short period of time to make good profit, the next 80 days, probably, will make less then half of that sum, as all the asics hit the market (and i'm not talking abut bfl), if 30% of bfl hit the market till September, which is probably not going to happen, 80 days will make about 50btc.... but this still profitable not as it is now tho...

Worthwhile investment if you could manage to part with the upfront costs. I'd do just about anything to get in on this.

^^^^ ... this. But let's try working backward. 80 days ROI at current difficulty, so 40 days to recover half the cost. Use that to calculate the maximum acceptable rate of difficulty increase (so the other half of the cost is recovered by mining for eternity). 40 days is almost 6 weeks or 3 difficulty increases. Cube root of 2 is 1.26, so as long as the difficulty increase is less than 26% per fortnight, you'll recover your costs. But factor in delivery time, and the exact point in the block difficulty cycle to get an accurate answer, and perhaps you won't make any profit at all. Do your math folks.

this +1

why selling such a profit maker?

do you happen to know the approximate shipping dimensions and weight?

Why does everyone forgets the RESALE value? What you're saying is that in 80 days this Avalon will have a 0 resale value... sorry, this does not look realistic. Once you add back a resale value to your ROI calculation, it is becoming very hard for difficulty to raise fast enough to leave you with a negative ROI. Everyone should do their own math, of course, but to assume that in a couple of months this unit will be as good as useless is an obvious stretch of imagination.

Nice try, but you'll need to find a buyer who's a bit weak on the math too, otherwise you'll only get its value for its remaining mining life, which won't make up the difference between what you paid and the sum of your mining earnings.

I've gone over my math with the help of http://coinish.com/calc and I think I've been wildly over-optimistic. 209BTC would be the breakeven price, assuming the rate of change of difficulty remains unchanged. 26% per fortnight would breakeven at 165BTC

But kudos on getting such a good sale price  8)

J35st3r: Can we keep this discussion to one thread? Cross-posting is tiresome...

Yes, good idea, but you started it :P

Anyway I think I've said all I want to say about this, I just got a bit of a bee in my bonnet about ASICs the last couple of days, no hard feelings. Have a good one.  :)
