Have you thought about putting together a referral team so that everyone can help to make a bigger profit on the site and even everyone win the prizes on the site? 
Referral team? Tell me more.
So as the site is now possible to win awards such as smartphone or hardware wallet, I decided to calculate how long a person without reference leads to get some of these awards, which is my case, I came to a conclusion that would take more than a year. With a reference team it would be possible to reduce this time with the participation of all the courses, and to repay this help would be the distribution of prizes for the members who helped!
