Playing on another gambling site may not make op win in my opinion for I do believe gambling company is gambling company and all of them are out to make profit. If op don't have the skills to make him or her successful since some casino are skill base then he can equally lost in any other gambling sites.
I'd be careful with the thinking that skill will someone effect the result of your gambling experience. Sure, some people might know a little better how to play games then others, but I think the house will always have the edge no matter what. Players should gamble with the expectation of having a good time and losing money. That's literally what it's about.
As for stake, I've always been pretty impressed with their resolution of my issues. I never even put in a bug report, just complained on their thread a couple of times about an issue and they resolved it. From my experience, they go above and beyond for their customers.
I didn't have any issues with stake pretty much the whole 5 months or so I was on there. It all started when I asked to change host. I know it might seem odd that could cause anything but I can assure you they had no issues taking 50k from me a month and they had no issues with me giving their chat community 5k a month. When I asked for a new host and banned casino from my account it seemed like stake turned into another company towards me. I just hope with your stake logo if you are getting people involved you are telling them the risk of KYC. I can assure you most who think of Stake will think their privacy is respected. Take care.
