Bitcoin Increase, my money has more than doubled

So, bitcoins seem to now be increasing week by week on mtgox. Late last year they sat around £8 GBP, currently they stand at £17.49 around two months later. Now that, is a pretty good increase.

I'm not keen on playing with real money in a kind of stock / shares market, so I started with around £4 when the market crashed a while back, and now stand with nearly £30.

So in the small time I have been trading with bitcoins, I have learnt to understand market movements, volumes, highs, lows, all the things to do with this process, and how to make money from it (even if it is only tiny amounts, it's still money!)
