Yeah that's one thing is you can only withdraw 50% from Richmond Berks. So that's technically about 1 month before you break even if you want to cash out right away. Not a big deal though. I can see how they need some sort of assurance that they will have some funds to make their property investments.
I signed up with your link but I'll probably hold of putting any money in bitzilla until I start profiting from the other one.
Thanks! I was thinking the same about Berks. I was taking a look at the site, looks interesting.
