... Had a look at Cgminer from JakeTri and in Read ME file I can't see any voltage settings Here is copy and paste with relevant information from ASIC-README file from https://github.com/jaketri/cgminer--hfa-options <arg> Set hashfast options name:clock@voltage0@voltage1@voltage2@voltage3:clk0:clk1:clk2:clk3
This command allows you to set options for each discrete hashfast device by its name (if the firmware has naming support, i.e. version 0.3+). Currently this takes as option the clock speed, 4 voltages and 4 clock offsets (voltage and clock offset for each of the 4 cores of the ASIC) e.g.: --hfa-options "rabbit:650,turtle:550@800,bee:950@905@925@975@985:-100:-50:0:25"
Would set a device named rabbit to clock speed 650 MHz using default voltage, the one named turtle to 550 MHz using a voltage of 800 mV for all cores and the one named bee is set with different clock and voltage for each ASIC core as following: > core 0 at 850 MHz (950 MHZ base clock with -100 MHz clock offset) and voltage of 905mV > core 1 at 900 MHz (950 MHZ base clock with -50 MHz clock offset) and voltage of 925mV > core 2 at 950 MHz (950 MHZ base clock with 0 MHz clock offset) and voltage of 975mV > core 3 at 975 MHz (950 MHZ base clock with 25 MHz clock offset) and voltage of 985mV Starting the device at a speed where it is most stable will give more reliable hashrates long term and prevent it interacting with other devices, rather than depending on the clockdown feature in cgminer.
Note: Setting voltage may cause a board reset and hotplug event on cgminer startup.
Is it possible to run it without voltage modification yet still individual core speed settings? If so, what would be the syntax? Thanks

Economy / Speculation / Re: Why the fiat price of Bitcoin is stagnant.

Bitcoin not only needs merchants jumping on the bandwagon, thats one piece of the puzzle. In order for the price to move, it needs consumer demand. All the merchants in the world could take Bitcoin but if ur average consumer doesnt desire to use it for purchasing then theres no new demand behind Bitcoin for being used as a payment system.
I think people will need to hit "rock bottom" by a failing fiat currency around them, the dominant USD would be a start. Then, they will start taking alternatives & freedom more seriously. Till then they are all just sheeps being lead to the slaughter and dont give a fuck about it.

Bitcoin / Mining / Re: It seems impossible to me to successfuly explain the concept of mining to...

When explaining mining to people, I liken it to gold mining. It was obviously modeled similarly. A very obvious and key difference though... While mining Bitcoin serves to bring new bitcoin into supply, like gold. Bitcoin mining further functions to secure the network & process the transactions etc... (if you want to go into how that works from there w/ ledger etc... so be it) - gold mining in no way functions to secure gold.
After laying out the above, it usually starts to click to people.
There are obviously more differences but it covers things pretty well.

Bitcoin / Mycelium / Re: Mycelium Bitcoin Wallet

So, I have a question regarding its backup format. Is it importable into other Bitcoin wallets or only Mycelium?
It is importable only into the Mycelium Wallet, but if needed, you can use the provided backup tool to decrypt it and have a standard wallet import format. Very good to know, makes me much more comfortable!
