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.
Even if you're being recommended of a gambling casino right from here then be getting ready that you're also going to make a certain research about them before you can start with the use of them all, it's not by name or fame, it's by the level of the satisfaction you have earned from it, but if you're such a gambler that won't mind the risk and use of any regular casino then fine at your own risk, but I our can always find some answers to your search right from bitcointalk of you explore.
