I hardly think a project that keeps providing information daily for months and months is intended as a scam. Just think about it logically? Would you go through the effort if you were trying to scam me out of money you already have? Nope. Is there a working model behind the game? Yes. Are data and content being provided constantly? You bet.

You can go right this instant and buy/sell on Counterparty. Perhaps you think it's difficult. Alright. Then you can wait a short while for the exchange service to be in place. That's a choice and you'll need to make plenty of those if investing in anything.

When you invest in something, you hope the people making the decisions act responsibly and think ahead. Well, luckily this is what the devs in FootballCoin are doing. Will this cost you some wait time? Sadly, yes. Will things be fully resolved? Yes. 

If you have any further concerns, and perhaps I can help, I'm glad to try my best to answer those.
