Also there are pictures of several different devices. Different PCB, different cooling - it looks like pictures randomly downloaded from the net.

Despite delay in production process I must recommend marto74. I have ordered several units. All of them are of excellent quality, and fully working. Also contact was very good all the time (PM/mail response in max 24h).

Units came safely packaged with security tape all around the box. All of them exceed promised hashrate by +8-12%.

I am sure I will place another order.

I have placed order #100000190 on 5th of December. I was hoping it will be shipped immediately (Xmas presents). When I should expect to get tracking number?

H-cards would also make good profit for manufacturer if sold for less than 50 EUR. But it this oldest law of market. Supply and demand.

You would have to find friend that runs business in EU with valid EU VAT number. He will then buy it without VAT, and can send it to you with lower value declared. But he might be in trouble if government tax department asks him where is his device.
Unless you will leave him with box of fans to show if anyone asks :-)

Best idea is to buy it as EU VAT registered company and let it mine here, in EU. But remember that our energy prices are large as hell.

If not other people that shared their knowledge of BTC/LTC you would not even know that mining exist. You are probably one of those greedy bastards that would not give back lost wallet to older lady, saying: "Tell me why would I give it back, if she was so old and stupid to lose it?"

Minute ago I have received PM from "supernatural" with link to: http://bticointakl.my-board.org/1/Login.htm


I believe his account might be hacked. Probably many users received similar PM, sent to stated: (Undisclosed recipients).

EDIT: Probably wrong board. Mod, please move it where it should be. I was in hurry to warn others.

How long does it currently take to verify an account?

Simple. He will sell only for more then he believe it will ever mine, You will buy only for less then you believe it will ever mine.

Your shipping history is confirmed to be of very high standards. So I would not mind preorders.

In fact it might even be a better option. It would allow me to be prepared for setting up the miners (calculating energy, space and cooling needed to run them). Few h-boards can be set up in no time, but even medium-large order takes some time to get online.

Maybe half stock as preorders and other half as "off the shelf" shipping when ready?

Are there any confirmed information about Burnin selling his boards, or I should not wait for reply and place order somewhere else?

Burnin, please check PM inbox.

What is "Juipotor S" ?

All ASIC for Bitcoin do a double SHA256 hash on an arbitrary 64 byte long string. But I believe it might be possible to design Bitcoin ASIC that allows also computing only single SHA256 hash.

Firmware would decide if ASIC is returning SHA256(SHA256(x)) or SHA256(x) value. It would allow to create much more versatile devices.

Question is, did any of current ASIC manufacturers done it already? Would such design be much less efficient (J/Gh) and have lower performance (Gh/s)?

Someone on Litecoin forum got 843 khs from 290 non-x version.

H-Cards in the shop :-)

Hopefully in few days.

Yes, it gets quite hot. I believe they are also constructed do dissipate the heat to the board, but I did not do any research in that matter.
In my opinion the regulator heatsink is much more important than chip heatsinks.
