Yes, although not to any significant capacity. I’ve got an inexpensive VPS running my personal Web site and mail server, and I use about half of its processing power to mine Litecoin.
Thus far, I’ve earned about 2 LTC. It isn’t a lot, but when you consider that it’s essentially free money because I’m not paying for my VPS’s electricity use, it’s a no-brainer.
Bitcoin mining has become so difficult that I can’t imagine recommending it to anyone. Stick to Litecoin or Peercoin - they’re up-and-coming altcoins that still have room for everyday miners.
Interesting.
I’m not familiar with Litecoin or Peercoin, so thanks for making them known to me.
