And also I think he don't need to seek for another casino since the one he need is to take a break or stop this shit forever since for what I see this didn't give him any healthy mind and the essence of fun is gone in his end.
I disagree. Avoiding your issues is the wrong way to stop any form of addiction completely. Such a method would only serve to amplify his addiction basically. That isn't how therapy works.
Gamblers who are addicted to gambling usually focus more on the money aspect when compared to the fun aspect due to which they lose control easily.
Op should shift to other crypto gambling sites which suit his requirements and slowly and steadily try hard to reduce his gambling addiction in various ways in order to control it. This is the correct strategy.
You are right, stopping must be a gradual process. The problem is that in total it will have a bad impact on gamblers who have already made betting a useful place. Reducing the portion of gambling a little better if you want to quit the addiction. What is the OP realm is also in fact he is not with all the applicable provisions so find another lighter alternative to get ready for a better one. So little by little, you can get a lighter bet.
