you mean 700% a week lol
What about doing something as stupid and simple as the following
Generate address each lets say 50BTC in it.Then you export all the privite keys and split them all using this website
http://passguardian.com/Then you distribute parts of the key to 255 differnt users. You then delete the privite keys off your computer and send away the parts.
Whats good about this is noone really has any money just parts of the money that if put together gets you some of the money. Also by keeping who exactly got peices quite none really knows who to talk to or ask to try to steal the money so to speak. Also another plus of this would be that you can set how many peices you need to reconstruct the whole thing. So you could set it at 51% meaning the majority has to agree.
