Mining Bitcoins

If you're insistent on using a regular computer for mining tasks, definitely focus on a coin that is CPU only.

Make sure to do some math, though, that the coin you mine is:

1. On a decent exchange.
2. Is worth it to mine taking the exchange rate into consideration.

From there you can swap them to Bitcoin and either keep and use or cash out with someone on LBC.
