3. Bitcoin mining with a pi

3.1. Intro

If you don't know what bitcoins are, or if you expect to get a miner that gets you rich quickly, skip this.

Long time ago, I had a small USB stick for bitcoin mining. It gave me a whooping 300Mh/s, which was about ten times what I got from mining with my display adapter. Due to various reasons, I shelfed the stick.

Now, I recently found it back, and although it is not really a profit-mining, it takes very little power, especially if connected to a raspberry pi. So, mostly for nostalgic reasons, I have re-activated my USB-miner.

The pool that I used in the past is now defunct, so I decided to use slushpool basically because it is as good as any (at least at this stage).

3.2. Setting up the miner

3.2.1. Make an account

You have to make an account, which will verify your e-mail

3.2.2. Install the software

First, install the dependencies:
apt-get update 
apt-get install autoconf autogen libtool uthash-dev libjansson-dev libcurl4-openssl-dev libusb-dev libncurses-dev git-core
apt-get install libevent-dev

Then, get a git-clone of the bfgminer
git clone https://github.com/luke-jr/bfgminer.git
cd bfgminer
./autogen.sh
./configure
make

And start mining:
./cgminer --userpass userID.workerID:any-password --url stratum+tcp://stratum.slushpool.com:3333

And see the satoshis roling in:
