My problem right now isn't the collateral. It's that your account password was recently reset which leads us to suspect you are not the rightful owner of this account.
Understandable. I recently got an email that had an offer to sell a .zip of a database dump from bitcointalk.org. After getting that email, I changed my password. In fact, I have changed it twice since I got that email. I will likely be changing it weekly, on multiple sites, just to stay safe.
Don't worry about the investment offer though. I found a few good resources to get coin without all of the fuss. I bought some on ebay, and virwox, and that got me where I needed to be.
