How to make a bit of money using bitcoin.

Alright, well chances are if you go to any tech forum or blog, you have heard something about bitcoins. if you haven't, that's fine too.
Basically, a 'bitcoin' is an online currency. for all you economic buffs out there, its a fiat currency, which means it fluctuates with demand. This is great if your into making micro transactions... which if done correctly can lead to some good profit. (i made over $300 in a month!)
