Carrying out personal research and having a first-hand experience matters when it comes to choosing a casino, but then always pay close attention to rating and review of the site, there are good casinos around but locating them I a big job for the gambler. If a casino have a good reputation and some fantastic games that can motivate a player then that casino can be played for as long as possible, and also can be referred to as a beginner.
On the reputation it can be easy to check here in the forum, and the most known scams rapidly get a reputation thread that anyone can check. On top of the research you can possibly undertake, you can also start little by little. Do not transfer too many funds in one go and do not trust too much if the sign-up bonus or other perks appear too good to be true. Basic precautions are recommended always.
Indeed! Threads are updated always so we as a user or bettor can always check about the site's reputation or if there's some scam and other problems that the site is struggling to do so, in that case, we can also avoid it from happening to us. KYC or non-KYC is good to go as long as the site has a good reputation and is trusted, but if you're someone who's not so confident sharing information then a non-KYC casino is for you.
