Regarding KYC, as I said before there is no guarantee that it is 100% secure. because the potential for data misappropriation can occur at any time, or other factors. Therefore, we must be careful when surfing the internet. Likewise with online casinos, for now, most online casinos impose KYC on their users. the reasons are very diverse, and one of them is as you said in this post. because of that too, we must choose a casino that really has a reputation that is quite trusted and credible. at least, our data can be ensured safe. because, they have a reputation that can be trusted even though there will always be risks that could occur in the future. but since KYC has become commonplace for now, I don't have a problem with it. it's just that, I will only do it at casinos that I trust and have a reliable reputation.
Same with how you assess the chance, choosing reputable casino will give you lesser worries, as you know and believe that they will not risk the business for allowing any types of exploit with the data that their customers/clients will provide them. Most of the time, when dealing online, we mostly check the credibility of every site before we handover our information.
Same drill with online gambling. Before you let the site keep your personal information, you need to make sure that you fully
trust the owners and everyone who's behind the platform.
From this viewpoint, you can have some peace of mind while playing and using the services as you allow them to have the copy of your personal data.
