One more investment of 0.1 BTC is needed so that the first investor can get paid.
I'm not that rich ... i was thinking to go to the 0.05 place where no one invested ....

just wanted to make sure no one got that place
You are not so rich to afford 0.1, but 0.05 is fine?
It's just half as that.
This post makes no sense under pretty much any point of view.
