The investor's get 2% of each ticket sold (applied to your balance each hour on the hour)

So you'll receive your full BTC0.45 once they sell enough tickets to cover that. Of course that 2% is split proportionately between the investors based on how much they invested.

Right now you're free to withdraw your BTC0.00001231 or wait until they sell more tickets and you get more.

Note: This is only my understanding, I'm pretty sure it's right but if Yabtcl could confirm this it'd be helpful.
