For comparison, ASICMiner Block Erupter blades producing 10 GHz ave or 12.8 GHz max just sold by ASICMiner for BTC49.99.
That's BTC3.9 / GHz min or about BTC5 / GHz average.
Looking at it that way, WIN.AVALON is a good buy.
Well if you want to compare then you have to take into account delivery dates.
The blades would arrive within a week. When will the Avalons arrive? How much will each GHz of blade hash-power mine in the interim? Without that data a comparison is meaningless: using your logic you could compare to BFLs (which would work out far cheaper on paper - but ONLY exist on paper).
Only thing you can easily do a fair comparison is other batch 3 Avalon securities - as those are likely to arrive around same time and have same hashpower and reliability.
Ok, lets say the ASICMiner Block Erupter (like the name!
) arrives 7 days earlier.
A 1 GHz miner is currently (diff = 11187257) expected to produce about
BTC0.045 per day on average.
For 7 days that's about 0.315 / GHz earned. So then subtracting accumulated income for comparison:
That's
BTC3.585 / GHz min or about
BTC4.685 / GHz average.
Probably should take the average (expected instead of overclocked) as the comparison number.
The two become even (at the current diff) in about 31 days. That is, at expected production, the Avalons could arrive 31 days later and the current price of Win.Avalon would still be as good as buying an ASICMiner Block Erupter.
