I think we all know here the OP has been flagged as fraud so I think it's clear about this site not really secure so never use it again and for your case better make a new thread on the fraud accusation board at least give a screenshot of the loss you get from this site. only giving advice that you should play gambling on a site that is active in this forum and has a good reputation
Yes it's true OP's friend has a negative belief for having joined a scam casino.
We can conclude that the gambling platform brought by OP is also very suspicious to use because it has a very large percentage of fraud.
We cannot trust anyone who has been involved in fraudulent activities because they have the opportunity to commit fraud again in the future.
Maybe @ditadurapura meant to give a review here to remind that the casino promoted by OP is a scam casino that has tricked him and he wants everyone who gives feedback here to be more vigilant so they don't become the next victim.
It's just that it's a shame that he didn't provide clear evidence and details of the case so we can't really fully believe it yet.
Hopefully he can immediately provide evidence and share it here so that we can understand more about this fraud case.
