Great, so you are definitely going for the long term! I will deposit more!
I am up to experiment! hehe To help others I sign up at this forum now to report my findings and have joined http://btcontracts.org 
I deposit 0.07 for this experiment.
so my dividend for this contract (5) is 0.02333333
I will reinvest 0.01166667
and withdraw 0.01166666
You can see my tryptsy account on the stats page
and I will state now that I am going to follow advice of site and reinvest 50% and withdraw 50% each time a contract completes. I will confirm if I do or don't get paid! I hope it works! the calculator says I will make have withdraw more than I deposit after 7 contracts!! I didn't have enough BTC to get in this early on makebtc but now I have some coin to play with so I hope this pays!.
