You have spoken well, and based on my own personal experiences, I very much agree with you, a friend of mine had once come across this new casino that was good looking, had very good varieties of games and comes with a very attractive sign-up bonus, he joined the casino, benefited from the bonus, and started playing on the casino by first depositing small amounts of money, they allows him to withdraw on countless occasions, he deposited and withdrawed several times without any issues, and because of this, he built a good trust on the casino and even proceeded to inviting all his gambling friends to the casino including myself.

After about 4 months of playing on the casino without any issues, he one day decided to make a deposit of $2500 to the casino, but as soon as the transaction was confirmed on his casino account, he was blocked access to his account, when he tried to chat customer support, he was immediately blocked too, he went to the casino's telegram group and immediately he posted his complaint, it was deleted and himself kicked out and blocked from joining the group again, this was when it dawned on him that he's been scammed, thank goodness that at this time, I havent even signed up on the said casino let alone playing there.
It turned out the scammers first made him trust the casino, and patiently waited for him to make a big deposit before they carry out their true intentions.

So, the safest way to be safe with casino is to only choose those that have proven their trustworthiness in a good test of time.
