You need to copy or at least get some advice from the Reddcoin community on tipping, they're doing it right compared to other coins. It also wouldn't be a bad idea to market this coin similar to the way they're marketing theirs. They're trying to be the upvote/tip/like of social media, Failcoin could be the opposite. they may even want to partner up seeing as Failcoin isn't a competitor. Just a suggestion.
