The hyip Cadillac Ventures is a scam. Here is an email that my friend received received from the Canadian stockexchange listed company Cadillac Ventures :

I apologize for not getting back to you sooner as I have been away from the office.

In regards to your questions – no we are not affiliated with this group and are currently working on having them cease and desist. As you continue your due diligence efforts on this company you should be aware that they have used information on their website to enhance their investment opportunities that they have taken directly form our website. This tells me there is something wrong.

I hope this helps.

Since they're lying, I'd stay FAR away from this one. Just my opinion... do what you wish. :D
