I'm really new to BitCoin, only been in 2 weeks and up 20% already. I trade mine through CoinJar.com.au
Something else to look at is mining. You can hire top end computers to mine bitcoin for you, i'm still trying to work out the ins and outs of this. I opened an account with one yesterday, cost me US$150 and in one day it mined just over US$1 ... The contract doesn't seem to have an end date and its a one off payment. So if one days action is anything to go buy I will hit ROI in just under 4 months and the rest is then profit.
I'm really new to all this so just dabbling. But hope that helps.
