Is it worth it for people with low hash speeds to bitcoin mine?  With my lows speeds of about 100mhash/s, is it even worth it to mine considering on a mining calculator i'd only end up with about 14$ a month. lol   Is mining only profitable for ppl with expensive rigs pushing a high hash rate, or can someone like myself with a low speed make it a semi-profitable venture.   I think the concept is really cool and I'm enjoying playing with it.      Anyways, thank you for your time and patience.    oh, and thank you in advance for any replies.
