http://ribbitchain.info/ << I don't see anywhere about the total available supply. Out of 400 million coins Airdrop (200 paid and 200 free) as team claim, where is the accounting? When will 1 Billion coins be in circulation? Is Charity the only pitch right now? Every shit coin does something for charity to get attention.
Back in April 2014 when Yellow coin did a legit airdrop with accounting, there were less than 2K users (all documented for public with bitcointalk id's. those days were altcoin peak - madness). Ribbit claims 13,750 users which is unbelievable and seems scam. Show accounting for airdrop (400 Million coins) or its a scam.
Yup me and my sister still didn't get our coins. I opened a ticket but the only thing they write back is that they don't have time right now and my case will be checked someday in the future (read as never).
