Peepcoin is one of them although it's a bit shady but since you are asking for coin referring program I recommend them you're going to get up to 1 million peepcoin there's little information about the coin but we'll see when it launches ..
Their website is down.. any other proposal?
Thanks
Site is now up the dev just updated the script for a major announcement next week ,you should get in while the list is not yet completed,the dev has a lot of surprises for this project even posting that users do not exchange for this coin,we'll see how good is this project..
