Let’s face it, mining digital currency nowadays is hardly worth it. It’ll cost you more in electricity than you’ll make in [insert favourite coin here]. Having said that, ASIC miners are all the rage these days for Bitcoin mining (which has a difficulty that is sky-high and will take supercomputers to get anything from it). Not so good for folks who want to try the lower end stuff (such as Litecoin) which use scrypt cryptography. Enter, stage left, the new fad of USB miners which use hardly any electricity.
The first wave of USB miners were Bitcoin only, but now they’re releasing dualminers which can mine both Bitcoin and scrypt coins.
To use one of these, you need to get the latest video drivers first (Nvidia for me).
Next, we need to get some software to run with the Dualminer. Unfortunately, none are available ‘off the shelf’, so we’ll need to compile a special version of cgminer ourselves. Download the git repository in a terminal with:
git clone https://github.com/dualminer/dualminer-cgminer
After the download is complete:
cd dualminer-cgminer
Before trying anything, make the auto and configure script executable. Open a window, go into the dualminer-cgminer folder. Right-click on configure and choose Properties. Click the Permissions tab and tick the box beside ‘allow executing file as program’.
Well need a couple of dependencies, so use your package manager to install libtool, libudev-dev and libncurses5-dev. Or use the terminal if you’re up to it.
Time to get compiling. In a terminal:
sudo ./autogen.sh
sudo ./configure –enable-dualminer –enable-scrypt –disable-opencl –prefix=/home/USERNAME/dualminder-cgminer
(obviously replace USERNAME with your username)
Continue with:
make && make install
Wait a little while until it’s all compiled, then run cgminer with:
sudo ./cgminer –scrypt -o stratum+tcp:ltc.give-me-coins.com:3333 -u wakuangdenongmin.1 -p 1 NOTE: for me I had to run it with sudo otherwise it wouldn’t detect my device Now wait. Probably quite some time. It takes me days to get about 0.01 of a Litecoin. The problem is exacerbated by the pool getting new blocks which displays: Stratum from pool 0 detected new block and the whole mining process grinds to a halt for a short time.
