A colleague from Malaysia who works in marketing made a good point:

Today, you need to know one thing: there are more people working than playing. Our strategy is to use 3-5 short video ads combined with a welcome bonus for marketing. Users who register on the webpage should call or send a message to greet, introduce themselves, and tell the customers that they can contact this customer service number with any issues. Later on, if there are any customers cashing out, you can use this to attract customers who haven't played yet by telling them which games are currently paying out. This not only demonstrates integrity but also achieves effective results.
