We have to wait for their response, perhaps stuffing Journalists (lie).
remember seeing some fake bitcoin news in cnn ireporter or something.

BTC is no get rich quick scheme.
More hash rate is (edit): and will be added to the network until mining is only marginally profitable, ...
.... rigs or away from BTC (gpu miners).


tell this to friedcat who mine btc for 1.6 mil usd per week.
We just had a very short time window(disruptive tech window) in which mining with an asic was wildly profitable: that window is closing right now.
Please do not read the argument as "mining will be unprofitable" or "will be dead". The point is profits from mining will fall from today's levels to a marginally profitable level (Which is still profit).
Friedcats ASICminers and Avalon miners are within the said window. The window hasn't closed as of now.
The fact that Friedcat will not be earning 1.6 mil usd per week for-ever shows profits will equalize to a marginally profitable level, Market theory.


GPU mining moved to LTC
rigs or away from BTC,  ... (gpu miners).
Same point. For more profits had to move away from btc.
They could have continued on btc at the said lower profitable levels.
GPU miners have or will reach the marginally profitable level.

There will be profits to be made, which is essentially reward for supporting the network with hashrate.
Unlike todays 180 day ROI ASICs, in the long term
BTC is no get rich quick scheme.
and mining will return to marginally profitable levels even for ASICs.(It hits the GPus, FPGAs, the 1st gen ASIcs, then the 2nd and so on)
A clear argument can be made on the timeframe which this happens but i believe it is inevitable.


Bitcoin mining has a lonnnnnngggggg way to go before there is any significant difference in profitability between those with a low cost of electricity and everyone else.
A clear argument can be made on the timeframe for ASICs when this happens but, i believe it is inevitable and not so far away .
Unfortunately electricity costs have have already hit GPUs on btc. GPUs had a run for approx (2009-2013) five years.

Now GPU rigs, sure -- miners should be packing it in pretty soon now, regardless of what they pay for electricity.
Forget moving to LTC for a sec ;even then, Should you really pack up a GPU BTC rig if you don't have to pay for electricity?(Only overheads come into expense)

As far as ASICs being profitable has to do with massive backlogs of hardware orders finally reaching customers.  The capacity coming online could still be limited such that ASIC mining will still be quite profitable -- not like today's level, but profitable such that there is breakeven in under a year.    
Current pricing schemes and ROIs are skewed due to the disruptive tech influence. For rigs to have ROIs under a year shouldn't todays short supply situation persist for the said duration? If the short supply persists for the current year the 1 year ROIs are the most likely scenario, but the short supply cannot exist for years to come. Isnt it just a matter of time before ASIC manufacturers truly can mass produce without order backlog?

572  Local / India / Mining fundamentally is only marginally profitable. on: June 28, 2013, 04:45:05 AM
BTC is no get rich quick scheme. Miners paying for power will cry very very soon, as they have always been crying. More hash rate is added to the network until mining is only marginally profitable, and the guys paying expensive electricity have no other choice than turning off their rigs or away from BTC, which happened at the end of 2011 and in 2012, and is happening now to all those that have no asic (gpu miners).

We just had a very short time window(disruptive tech window) in which mining with an asic was wildly profitable: that window is closing right now.

Good luck to guys with low power costs.
Happy hashing.

Not for the Faint of heart.

Jalapeno Flash howto.

This howto will walk you through flashing your BFL Jalapeno.

PLEASE NOTE: THIS WORKS FOR ME. HOWEVER I TAKE NO RESPONSIBILITY IF YOU BRICK YOUR JALLY. MY JALLY IS A "HOT" MOSFET UNIT AND I HAVE EXTRA COOLING. EVEN "GOOD" MOSFET JALLYS SHOULD USE EXTRA COOLING AS STOCK JALLYS ONLY GO TO 7 GHS, THIS CAN TAKE YOU TO 8+.

not all jallys will reach this, depends on the chip grades you have. my 5 ghs has two good chips, 15 engines each. YMMV.

AFAIK all jallys with aluminum heatsinks are "good" mosfet jallys. look at Q1-12, if you have 2 different sizes [6 one size, 6 another] this is a unit with "good" mosfets - you should be good to go. mine is a "hot" mosfet jally (all mosfets same size) and with LOTS of additional airflow Im OK. but HEATSINKS ON YOUR MOSFETS (AND 1850 CHIP IF YOU CAN GET TO IT) ARE A GOOD IDEA.

seems at least some 7 ghs jallys (and 7s only?) come with heatsinks on the mosfets now. see warhark187s post here.

temps @ 23 C ambient, caseless, top fan blowing down, with 120v 22 watt "muffin" side fan:

before flash  30C 3.1v
after flash 37C 3.1v

WHAT YOU NEED:

source code from BFL
https://forums.butterflylabs.com/announcements/3282-bitforce-sc-firmware-version-1-2-5-a.html

and/or

the .hex file from BFL, just in case you have trouble compiling it (I did initially).

atmel studio 6.1 - I grabbed the Full installer (806 MB)
http://www.atmel.com/tools/ATMELSTUDIO.aspx

AVRDragon:
http://www.atmel.com/tools/AVRDRAGON.aspx

digikey seems to have the dragon also.. I had already ordered from atmel though.. DOH
http://www.digikey.com/product-detail/en/ATAVRDRAGON/ATAVRDRAGON-ND/1124251

USB AB cable for the Dragon
http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&DEPA=0&Order=BESTMATCH&Description=usb+ab+cable&N=100006519&isNodeId=1

10 pin JTAG cable.
something like this . its just the 1st link I found
http://compare.ebay.com/like/190681930364?var=lv&ltyp=AllFixedPriceItemTypes&var=sbar

I just cut down a 40 conductor IDE cable. (mine is cut to 2x6 as i was sloppy)



thermal tape or paste if you disassemble your jally. the chips are bare silicon so I recommend you reuse the tape and just add some paste to fill on the voids if the tape falls apart. or just use new thermal tape. using paste alone is a good way to crack the chips if you are not VERY careful. the tape helps cushion the heatsink.

cgminer 3.3.1 - its the earliest version that will properly handle the 1.2.5 firmware jally. my picture below shows 3.2.2 but I compiled from git just before 3.3.1 was released.
https://bitcointalk.org/index.php?topic=28402.0

my heatpipe jally had plenty of clearance for the middle (now end) IDE connector to slip on without removing the heatsink.

aluminum heatsinks probably will require you to remove it to get the cable on the jtag connector. if you cant get the heatsink back on with the cable attached you will need to find a way to keep the chips cool while you program them. right after programming they will be tested so will generate some heat. danattacker used the metal backplate pressed down on the top of the chips after he masked off the surrounding areas with masking tape.

SEE DANATTACKERS POST BELOW ON ALUMINUM HEATSINK JALAPENOS. DO NOT RUN YOUR JALLY WITH NO HEATSINK!!



ATTACH THE CABLE: (IMPORTANT: REMOVE THE BLACK ANTISTATIC PADS FROM THE DRAGON BOX BEFORE POWERING IT UP IF YOU RUN IT IN THE BOX AS I DID)

power off the dragon and jally. connect one end to JTAG on the dragon, the other to JTAG 1 on the jally. MAKE SURE PIN 1 GOES TO PIN 1! plug the dragons USB and the jallys USB cable into the computer (the dragon did not recognize my jally until I had the jallys USB cable plugged into the computer). the dragon draws power from USB so it will come right up. then plug the jallys power cable in.



CLEAR THE JALLY.

my 1.0.0 firmware 5 ghs jally had the security bit set.. which means you cant program it or read the firmware. so to clear it you need to erase the chip. THIS MEANS THIS IS A ONE WAY TICKET.

[THIS SECTION I WILL FILL IN MORE A BIT LATER WITH SCREENSHOTS AND STEP BY STEP INSTRUCTIONS. I DONT HAVE THE JALLY IN FRONT OF ME AND HOOKED UP SO I CANT DO INCLUDE ANYTHING ATM - JUST GOING FROM MEMORY BUT ITS EASY]

fire up Atmel Studio 6.1. hit Tools, Device Programming. under Tool, chose "Dragon" under Device, choose "AT32UC3A1256" at this point it will probably want to flash your dragon to the latest version. let it, it will take a few minutes. when its done, hit "apply", it should read your device signature. then click "read" and all sorts of info should be displayed. youre ready to go. hit "erase" NO TURNING BACK NOW!

PROGRAM IN THE .HEX file

chose .hex image you grabbed before and chose "program" - thats pretty much it. dont even need to compile anything, or even unplug the JTAG cable.. just fire up cgminer and watch it go. cgminer had several false starts initializing it but after a minute or so it dug in and was mining.

1.The Cease & Desist

"f found guilty, the conference organiser for Bitcoin, the decentralised digital currency, could face fines of $1,000 - $2,500 (£650 - £1,600) per violation, or per day if violations are less frequent, plus criminal prosecution which could result in five years in prison and a fine of up to $250,000."
How do you prove they are a money transmitter?
Hope they don't keep Avalons in their office.

2.The news comes just days after  Gox, suspended users from withdrawing their Bitcoins as US dollars for two weeks.

I see a coordinated attack. Though, they seem to have the wrong target in the case of the foundaton.

to what ?  scrypt ?  Wink  LTC already use that tech  Wink

If for some reason that's what needed, sure, why not?
I don't think the Sha256 ASICs can be modified for Scrypt. They hold enough hashing power to ensure SHA 256 remains. Scrypt would be a hard fork which the ASIC users wont adopt. Most users will protect their investment at any cost.

The've announced LTC quite a few times via a Press release, twitter and their support channel. They keep postponing it without announcing a date.
The press release in april or may mentioned LTC and price spiked to $3.
It went back to $2 shortly.
The FB release says the same thing as the press release pdf. Price spikes again to $3.
I pretty much expect it be postponed again. Gox has bigger troubles to deal with .

Wow, LTC is considered a Scam coin?
Isn't Scrypt Jane an added feature, Designed for ASIC resistance , it makes sure even any disruptive tech doesnt have as significant effect on the network as that is seen on BTC. Since people have put so much of money into ASICs BTC can't adopt Scrypt.



Scrypt is not ASIC resistant at all. FYI: it was supposed to be GPU resistant too, and LTC FPGAs are being developed right now.
True, with each passing day. Ive been following the FPGA project closely., But better ASIC resistance(resistance seems wrong to be used now that FPGAs have been developed, maybe a less disruptive effect than the FPGA to ASIC jump in BTC), compared to BTC, could be the inability to achieve the Mh/$ ratio of 1st generation BTC ASICs to GPUS.
