But not all of them are willing to take the time to look for more information about which sites they can use to bet on and that is up to them.
Many gamblers end up playing in shady casinos for being too lazy to make an effort to search about the platform. Thats the price to pay for not being careful. Most of these gamblers are newbies and dont have clue about the reputation of the site. Because if you value your money, you wont entrust it easily to a casino/sportsbook without checking their background and reputation right? Its not hard to do through google or on this forum.
I’ll also add that when such players lose a lot, they will be completely disappointed in gambling. And they may even say to themselves: "that's enough, I'll never play in a casino again...".
In fact, they won't play anymore. And they just had to first figure out where to play, where not to. And which casinos are honest and respected by players with a lot of experience.
