Funny thing is the idiot who is claiming that COSS is a scam is a member of a team who created SINT, although I don't really know what his position is there.
But if he's part of it and doesn't even understand how exchanges work, I'm pretty sure that his coin is a scam (which is also an exchange so maybe he's just shitting on the competition).
Well, it may not be a scam, but what I have to stay is that
I opened a support ticket last year and it still has not been answered. This COSS team is a complete joke! They have not credited my ETH transfer and I still cannot withdraw any of my earned tokens.
