That is such a lie. I made about 5 bets, 3 of which were live. I guess the point is that I increased my deposit 4 times, so why should you pay it out, if you can just declare me an abuser and not pay anything.
I read other posts with complaints about duckdice.io, in which I noticed a large number of dishonest actions  of this casino. So my advice, stay away from them and do not carry their money. There are much better alternatives.
