The sites you mentioned are good enough so far and they are known in the forum as reputable casinos. However, you may not directly advise anyone to use any Site. Gambling is already very risky so it is always better to advise everyone to stay away from it. So op can recharge himself with ideas from here and then decide which one will be perfect for him.I personally use stake.com the most because I have been gambling here for a long time which makes it user friendly for me.
I don't think it is a good way to give advice directly to someone, always suggest with and the rest should be explored and used by the user. But the casinos he suggests are not bad for gambling. And yes gambling is very risky because you can become winner at once at the maintain you can lost your whole fund at once. But gambling with the responsibilities and with the own limitation can be make the gambling little safe.
Yes, no one can ever guarantee who will win or lose in a gambling game, so one should never give financial advice on gambling. the person who gambles on the gambling site has to take full responsibility for the loss. Therefore, a gambler should do his own research and not jump to any site by listening to other's advice and then gamble there. But of course a reportable casino site should be used. This will at least allow him to make faster deposits and withdrawals
I just commented and I only said that I myself use stake site which is user friendly for me. But I did not advise him to use it. no one can play free gambling on any site so he has to deposit his money everywhere. So since financial matters are involved here everyone should choose a site according to his own preference. as I take it and all other professional gamblers choose too in a same way. A person who chooses a site based on the advice of others is never a professional and noob gamblers will always lose. Loss is not an issue as we all know that Khan will have both loss and profit in gambling so accept this and gamble. But if you use a reputable gambling site, you can at least be sure that there are no bugs in their site and you can gamble smoothly.
