Bitcoin mining is so last year. Put your expensive GPU to use
cracking passwords.
When the Bitcoin mining craze hit its peak, I felt the tug to join this new
community and make some easy money. I wasn't drawn only by the money; the
concepts behind Bitcoin mining intrigued me, in particular the new use of
graphics processors (GPUs). With a moderately expensive video card, you
could bring in enough money to pay off your initial investment and your
electricity bill in a relatively short time.
