Why are you even asking this question?
Can't you just use your brain and come up with multiple examples of bad/shady behavior by a crypto casino?
Withdrawals taking forever,really slow customer support,scam accusations left without any answer and proof.
The fairness of the games cannot be verified.Having rigged games,where you are guaranteed to lose,if you bet a big amount.
The list can go on and on.

OP,are you obsessed with duckdice.io?Did they scam you with a big amount of money?
You have already made a forum thread about duckdice.io.There's no point of posting on other forum threads about your problems with this casino.Maybe duckdice.io is a scam and a bad casino.I don't know.
I haven't used that casino and I never will.
