You're right man! We should have to be an early bird in able to get profit from ponzis, Im also an early bird in honestdoubler , made profit and stopped before the site turned into shit 
I'll take note of that early bird strategy, but it's hard to find a new one, some don't post for announcement here that they launched a new site. Most who announced here are just users and looking for referrals not the actual owners of the site.
