Crypto can help him by following Bounty, so he can earn extra income from the bounty. Invite him to create an account in this forum and start participating in bounty, use this to earn extra income. Good luck
Another invitation for more shitposters perhaps? 
I mean seriously? Do you think this forum will help him for the better if he joins now doing bounties? Look at you, I'm sure that you're realizing now that with your rank, doing signature camp is not really worth the time and effort because of the small money you earn at the end.
The best thing he's friend can gain to this forum is the knowledge in trading and investing, nothing more nothing less.
