Nothing wrong with trying a new casino from time to time, however the problem I see most of the time is that instead of being cautious and just deposit a small amount of money on their wallets and see if they like the games and the promos the casino offers, many newbies deposit a lot of money on their accounts, and while this is not a problem with honest casinos we also know there are some casinos out there that are managed by dishonest owners which will keep that amount of money and scam the customer, and even if the community does its best to warn users which are part of the community and other people looking at their posts about this, there is nothing they can do to recover the money which was stolen.
yes, most of the users are not that cautious when trying out new things and this is quite important
even online security is quite underestimated for new users, like the basic, not using the same email + passwords, etc...
we have a long way to go.
agree with you about not being a problem to try out new casinos but people should always be careful about their information and data
