Sigh, this GameCash is an obvious scam. I know a lot about the gaming industry and none of the people in the team are known in the gaming industry. Plus, these profile look incredibly fake just like the Lust ICO.
In addition, the difference between the Pre-Sale token value and the ICO token value is ridiculous.
PRE-SALE
1 ETH = 2100 GCSH
ICO
1 ETH = 550 GCSH
Who the hell would want to participate in the ICO?
And why is the pre-sale going on for 14 days?
This is an obvious and quick cash grab. Ask the developer to record a video of themselves and I bet you that they can't because these profiles are fake.
Also, there is no way that STEAM, PSN or Xbox Live are ever going to incorporate game cash and yet it is on their roadmap.
This is very likely to be a scam.
