Newzbin.com shutdowned in 2011!
Some similar sites only accept bitcoins, I remembered it was only $10/coin, but it was too hard to buy one.
So I started to mine just enough to pay for the subscription
I have regretted that I turned off the mining software.

Then last year, When bitcoin price suddenly jumped up to $200/coin.
I started to read more about it, more interested ever since.
