You should just be careful using this site as they disclose your information to third parties apparently, and at any point there is a risk that your funds may be seized for an "allegation" that you won't be told any details about. As a result you should be careful about what information and data you are giving the company if that is of any importance to you and I would question putting any major funds into the site. If you are just making small time predictions you should be fine.

Feel free to look at my other posts for details.
