By the way, is it quite useful to share our wins or betting strategy?
In my side, it is not really useful. I personally prefer to not sharing anything related to my gambling activities.
Sharing wins may aim to provide motivation to gamblers, that casinos really do pay out winnings. But I'm not sure gamblers need such validation.
When it comes to betting strategies, it may be something that other gamblers could emulate and apply. But we know there will never be a strategy that consistently yields wins for gamblers. Some gamblers won't care much about strategy. They rely more on luck.
