My favorite and I guess everybody's favorite is the signature bounty campaign, not only do you get to earn new coins with good potential if you are participating in an altcoin campaign but also get to know the latest buzz and new technology and innovation in the industry, everybody wants to rank up so they can have the biggest stake in the campaign and since the implementation of the merit system members has dig deep to share their opinion to contribution on every topic to get the nod of the community.
