Hehe Punin no offence here, but after the announcement of a lot better than expected performance KNC 28nm chip you begin 55nm chips sale started.
All we known that soon BF chip will be worth a penny.
1) You seam to not understand what you are talking about. It is not important if it is 28nm, 55nm or 1nm. The power efficiency is important.
2) If you order now, knc will not ship until November 15. I believe punin will offer immediete delivery after shipping current batch.
You did not understand what I mean.
KNC start deliver many orders now, thousand Jupiters/Saturns. All this October machine get free 25-30 extra hash power. After deliver that, power efficiency BF chip will not matter because the difficulty will increase drastically.
You still don't get the point. KnC is short-time amusement until the big guys like HashFast or CoinTerra get on the playground, Bitfury is not. When some time next year KnC owners shut down their miners because of energy inefficiency, these chips punin auctions here will still be happily mining. KnC wastes double (yes, double) the electricity compared to anyone else. In November it is unimportant, but in April it will be crucial.
