Did you notice the price set by Betfury in their twitter giveaway? It was at ~$350 for 5000 BFG so that gives us approximately $0.07 per token. Will that be the listing price on the exchange? That's too cheap don't you think? The mining price per token is at $1.13 for slots and $3.14 for in-house games as of now so the 5000 BFG should at least be worth $5650.
It's not when you count in the possibility of winnings and play dice with highest odds, real mining cost comes closer to $0.07.
