Not all but majority of them unfortunately. But nobody can disagree Luckyfish is probably the worst!
I am sure this casino won't be worst than 1xbit but their possibly disastrous to the extent nobody can disagree, the question is now why did some people still use their service in spite of all the shady and scam activities done by the casino? Are some gambler that naive?
They write lots of fake reviews and not many people know bitcointalk, i think lots of people discover this site after being scammed. Sad reality.
It indeed a sad story but it still the fault from the end of those that were scammed because a simple Google search using the site name +scam i.e (Luckyfish +scam) is enough to know/get information anout the scam activities of the casino especially those that have been reported on this forum.
