It's not a problem if they deliver on time. The only reason so called "pre-mining" is a problem is when manufactures fraudulently advertise and early delivery date and then delay the delivery date in order to charge a higher price and still use the equipment to mine for their own account.
So true. While I would prefer to have an unused miner, the truth is these products aren't going to be running very long. It's very unlikely any pre-mining will effect reliability, and thus customer profits. I just want my unit shipped ASAP, which they do. |

Precisely, we are the owner of the IP inside the A1 chip
Innosilicon is proudly announcing that BitMine AG, a leading bitcoin mining system supplier, has licensed its ultra low power Hash IP Core for production
Bitmine says they own it. Innosilicon says Bitmine licensed it. Innosilicon isn't a brand new company. Bitmine is. I'd give the benefit of the doubt to Innosilicon. |

|
Still, this does not change the fact that Innosilicon does not have the rights to produce and distribute the A1 chips without bitmine's permission.
Doubtful. Innosilicon was the one who actually engineered the chip. |

Joshua Zipkin even called me an idiot and hurt my feels. I would quote the post, but he pains me each and every time I read it.
You could try sewing him for it. |

tl,dr: brute forcing a private key being it 128bit or 256bit is impossible today it's stupid to even try, and I've already provided the math for this and we do not disagree on this, my point is, in the next few decades we will eventually reach the point where we will have enough computing power to be able to do so as happened in the past!
I'll let Bruce educate you. One of the consequences of the second law of thermodynamics is that a certain amount of energy is necessary to represent information. To record a single bit by changing the state of a system requires an amount of energy no less than kT, where T is the absolute temperature of the system and k is the Boltzman constant. (Stick with me; the physics lesson is almost over.)
Given that k = 1.38×10-16 erg/°Kelvin, and that the ambient temperature of the universe is 3.2°Kelvin, an ideal computer running at 3.2°K would consume 4.4×10-16 ergs every time it set or cleared a bit. To run a computer any colder than the cosmic background radiation would require extra energy to run a heat pump.
Now, the annual energy output of our sun is about 1.21×1041 ergs. This is enough to power about 2.7×1056 single bit changes on our ideal computer; enough state changes to put a 187-bit counter through all its values. If we built a Dyson sphere around the sun and captured all its energy for 32 years, without any loss, we could power a computer to count up to 2192. Of course, it wouldn't have the energy left over to perform any useful calculations with this counter.
But that's just one star, and a measly one at that. A typical supernova releases something like 1051 ergs. (About a hundred times as much energy would be released in the form of neutrinos, but let them go for now.) If all of this energy could be channeled into a single orgy of computation, a 219-bit counter could be cycled through all of its states.
These numbers have nothing to do with the technology of the devices; they are the maximums that thermodynamics will allow. And they strongly imply that brute-force attacks against 256-bit keys will be infeasible until computers are built from something other than matter and occupy something other than space.
No, it's not going to happen in a few decades. It will never happen. |

I sure hope one day that someone invents a faster, cheaper, instant way to transfer value from person to person over the Internet that cuts out legacy banks all together.
Something that could to that internationally would be worth thousands of dollars per unit. Wow! |

Bitmain. They actually deliver when they say they will. That's way better than shipping late with a minor speed increase since difficulty goes up way more than 10% every 10 days. Syke - bitmine ships with massive delay and ~30% reduced hashing power. Not Bit mine, but Bit main. An unfortunately too similar name, but Bitmain pwns. |

Yeah lol, people do that mistake alot when extrapolating, but when you have 5-6 decades of data I believe it is safe to make an extention to the next decade or two
Go ahead. Extrapolate a decade or two. In fact, go ahead and extrapolate to the theoretically limits of the perfect computer harnessing the entire energy of the sun. You still can't even count to 2^256, let alone do the calcuations to brute force a Bitcoin private key. Re-read the graphic in post #2. |

Another option is to underclock and run 4 off a single PSU.
Run the math: you may find that it makes more economical sense to save $100-$200 on additional PSUs, rather than getting an extra 10-15% hashrate by overclocking. Everyone's situation is different.
Agreed. With Bitmain dropping the prices so low, the cost of the PSU is becoming significant. |

I'm not aware of any other Bitcoin mining equipment manufacturer in the world that offers such a good customer protection. Our primary goal is customer's satisfaction and we are working hard to achieve this.

We'll give you an update on where we are at every Tuesday, how about that?
I wonder if it is Tuesday yet in PA. |

As per US law, mail order refunds are in US dollars. Please do not maintain the unreasonable expectation that we're going to break that law.
US law does not *require* refunds to be in US dollars. Businesses are free to "barter" for payments of services and products. |

Guys, please answer my questions above. Do you think it's worth it if ROI is 5 months? It's 3 months without VAT and PSU, but 5 with them.
I don't like a 5-month ROI. But I think your 30% adjustment estimate is too high. We haven't had a 30% yet this year. Rerun your estimate with 20% adjustments. |

Yup. Phone numbers don't work. Email addresses don't work. Physical address doesn't exist. Server hosted in Slovakia. Go ahead and call this one.
SCAM.

They take Paypal. If you got some extra $ to blow, go for it.
Actually they don't. Not available at this moment.
PayPay or Credit Card

I have one. I was also afraid that they are crooks. Now I think they have the best price on the market.
Excellent. Let's see a photo of it. |
