I have faith in this project, I do not know why I've heard it is scam.
People above were talking about a scam monacoin airdrop, not that mona is a scam. Mona coin is actually one of the few coins that have actual usage and merchant adoption.
Don't mind them, It's just their strategy to make others dump their Monacoin so that they can buy more at a lower price.
Compare to other cryptos based on their total number of supply, circulating supply, markets and usages.
Monacoin price should be at $35+ by now. This coin has a great potential as a medium of exchange for online products and services.
