I don't think you're promoting not really promoting but shilling this casino because you like playing here or have a good experience playing here, it's either you are part of the team or you are getting paid to shill, if you're part of the team the admin should fire you if you get paid to shill this they should stop cooperation and of all the casinos here you attacked a casino that is user friendly and with good reputation just to promote your own.
Why would he be fired by their admin? If you are the admin, won't you like it when your casino is being promoted by someone else? If he is being paid to shill then he is doing his work properly so I don't think he can get fired. I agree that duelbits has a good reputation but I don't know about btc365. This site sounds like bet365 and this makes me doubtful about them but they are not the real problem here.
The problem is the OP based on how he acted. Acts like this are not new but there will always be company who can't compete fairly. They think this will make them succeed easily but that won't happen anymore because they will get a bad karma for doing this.
at first glance, their stats seems dubious for me. do they really have more than 4k+ online users and paid about more than $10M? though they registered this site this May 2022, but how their site is set-up seems to be a fly-by-night casino. anyway, don't know how legit are their numbers. but if they are doing good, great for them. players should be more careful these days as we don't know how authentic they are.
