The website www.prosperousboom.com is currently a very suspicious one, and I do not recommend that it be trusted. What I found strange about this website is that it doesn't provide a secure connection for their sensitive web pages, like the sign-in and registration pages that collect your personal and other sensitive information.
The Suspicious Website www.prosperousboom.com

Legitimate websites use a secure connection called SSL to protect sensitive information like your username, email, password and other information that are sent from your computer to their websites. But, this website currently doesn’t have this type of security or protection installed.
A web page that is secured, website address starts with “https://” instead of the unsecured default “http://”.
So, based on the information collected for this website, we do not recommend registering or signing up with it. If you have any information about this website, please post it in the comment below. You may also want to view the comments (if there are any) made by other users below.
