In my opinion, the first sign of gambling addiction is that the person regrets the lost money but again and again visits the gaming platform in the hope that today he is lucky and winnings will contribute to changing his life for the better. He comes to the casino not to enjoy the game, but for the result, which often turns out to be not what he expects.
The manifestation of stress, depression, gambling with credit money, etc. is already a neglected degree of gambling addiction which is very difficult to cope with alone.
True, one of the characteristics of gambling addiction is to open a gambling platform constantly even though you always lose. People who are addicted to gambling cannot control themselves in the game, because betting is not for fun. People addicted to gambling are emotionally unstable, they will try to get money from anywhere in order to keep gambling, people who are addicted to gambling will experience financial problems because money is used to gamble, because gambling is a top priority.
The characteristics of a simple gambling addiction can be seen from the desire to increase the value of the bet, the difficulty to stop, the dependence to continue betting even though you have lost repeatedly.
