Bitcoins are digital currency, as explained here:
Step 1: First Get a BitCoin Wallet
Their site is perfect for those new to BitCoin and not too into the technically side but rather looking for a quick and easy setup.
Once you're signed up,
1. Click Account Settings on the LEFT side bar.
2. Click BitCoin Address at the top menu.
3. Click the + Create New BitCoin Address button.
You'll see a new BitCoin address pop up below.
It will look something like this: 31uEbMgunupShBVTewXjtqbBv5MndwfXhb
Select that text and copy it to your clipboard.
Step 2: Next Begin Mining Bitcoins
Once you have an account and are logged in, click the CHANGE button of the BTC cash out section and paste your wallet's BitCoin Address there. I also changed my payout threshold to the minimum of 0.01000000
Now you're ready to start mining!
Step 3: Download the BitMinter Client
(*NOTE: be sure to have latest Java Runtime Environment installed)
Run the downloaded bitminer.jnlp file to open the Bitminer Client.
Step 4: Start Mining!
When you open the BitMinter Client, you'll be asked to login. This is asking for your BitMinter.com username you created. That way and mining you do will be credited to that account.
Start the Mining Engine!
After you login, click the Engine Start button and begin mining!
You'll see the speedometer displaying your current mining stats, click the icon in the bottom right corner to enter Performance Mode which is faster and watch the Bitcoins add up!
It's a very slow process especially depending on your graphics card hardware, but you're now up and running!
Your BitCoin will Auto-Transfer to your CoinBase wallet where you can Send them as payment or Sell them for US currency.
Step 5: Additional Notes
Some settings you might want to adjust in your BitMinter options are to:
• Login Automatically
• At Startup > Start Automated Devices
NOTE: You probably only want to check your Graphics Card (GPU) as the device to use, as BitCoin Mining works better with graphics cards rather than your computer's processor (CPU). The CPU doesn't yield as much data and uses a lot of extra energy.
• When new devices connect: Always start Device
