I knew people whose into physical gambling that will only go home once they lost every penny they have, that will be the only time they will think to stop or when they can't borrow any money from someone they know that is also in the area. This attitude is normal to those who gambling physically but to those who gamble online it's easier to limit ourselves to avoid more losses since we can stop ourselves to deposit more money in casino, we can limit ourselves per game and only deposit money we allotted for gambling, it's either lose or win.
I have a different opinion, I think it's easier to quit in physical gambling rather than online gambling because in physical gambling you're not entirely gambling, but you can also have fun with your friends and have a drink. In online gambling it's make you easy to deposit your money using any digital wallet fiat or crypto. Most of people who're gamble on online casino is to make money and no one will stop you to gamble.
