You simply have no clue, seriously. Antminer S4 is $1250 PLUS shipping. As of right now it is 4.13 BTC to US for each (2Th), so for 6Th it is 12.39 BTC.
The equivalent hash in S-30 would be 9.29 BTC.
You're welcome!

can't you do some math? Sp-35 is 5.5th in December for $~3600 (after assumed $320 compensation) with $30-50/mo more electricity usage vs 4.5 TH RIGHT now (a full mo earlier).
Fair price for Sp-30 is ~$3100-3300 or at least 9 BTC. If you want to give discount to allow for some profits to buyer in comparison from buying from manufacturer-fine, but don't be stupid.

It is your business, but why exactly you are selling 4.5TH machine for 5.2BTC/$1800 when someone bid 7 BTC for another machine here and antminer S4, for example, which is less than half of S-30 (2Th vs 4.5TH) is selling for ~$1400 (~4BTC) with shipping?

Fermi's paradox is funny because it assumes that there is no hard evidence of the existence of extraterrestrial humanoid species while in reality there's a shit load of evidence that is unfortunately suppressed by the mainstream science.

The logical conclusion from this statement and the fact that we don't see any Type 2 and Type 3 civilizations (Fermi's paradox) is that EVERYWHERE else bitcoin-like technology never appeared.

Good point but is 12% really significant? That's why he's the CEO and gives out vague answers with lots of room to speculate. I for one would love to know their narrower range.

so far it is still declining. I am waiting for some large mining company with higher electrical cost to go out of business (cough-K-N-C-cough) before we reverse.

I do lump all the asic manufacturers together because they have all done exactly what I said. Your heroes, Asicminer, are one of the worst offenders because they mine themselves and by proxy whilst telling their customers that they want everyone to have a chance to participate in mining. What they actually want is the chumps to keep financing their mining activities by believing that they will make some money from their purchase.

There's NEVER been one asic manufacturers who has said "thanks for your order, we will do everything we can to keep you as a customer and help you to make money. We'll make sure you get more hashing power when you need it, not when we decide we'll give you some more".

so it is reasonable to ask for at least 8-9 BTC.

I can sell you a nice 8mb 1920x1680 signed picture of my Sp-30 hashing as expected for $200. Deal?

I glanced over the paper and have a couple of perhaps naive questions:
1. As bitcoin has economic value, I don't quite understand how this would work with sidechains. Suppose I transfer 1000BTC to a sidechain, but whatever changes i make will result in a loss of purchasing power of the "new bitcoin" in my sidechain. However, since I have a two way peg, i would be able to transfer my "new bitcoin" back to parental bitcoin chain at the 1:1 ratio?
2. Alternatively, if my "new bitcoin" chain will be successful, then bitcoins will 'evaporate' from the parental chain toward my chain, but it is intuitively unfair that initial coins in the "new bitcoin" will have the same value as latecomers 'new bitcoins' that will 'evaporate' later from the parental bitcoin. If no equal value, then how that difference in value would be determined?
3. Will parental bitcoins acquire more and more value as sidechains accumulate or will they lose value toward zero as value is transferred to sidechains?
4. I think that authors might need to introduce some value "entanglement" between 'locked' bitcoins (that moved to sidechains) and the rest of bitcoins in the parental chain. This way, if sidechains acquire additional value this value will be reflected in "non-locked" parental bitcoins, otherwise parental bitcoins will be unaffected by sidechains growth and will eventually lose value.
