Yes, i have been scammed in past, but wasn't by a full project, it was more direct by users.

After be in casinos for long time is normal to meet lot of people, some people looks realy nice online, at the point when they ask you for loans and you think you can trust them. But is easy for them to hit and run, then come back with a new name.

I has been scammed other way, by casinos for example when they block my balance because they say i was doing something out of the rules, maybe it wasn't a full scam, but for me feels that way.

At end is hard to not get scammed, because we are under an economy/hackers ambient. and all of we just want to get more bitcoins
