I have addressed this issue before. We are cleaning up the code and making sure everything is presentable. As you can see we already have people complaining about the Exchange's code, so we want to make sure we don't get trolls when we release Lithium's source code.

I think we are offering a very low risk investment. We are giving away the Exchange's code as a bonus and that alone is worth atleast a couple of bitcoins. I you don't feel ok investing until Monday, I respect that and feel free to participate in the Free Distribution.
