If he was afraid to lose it somehow then he probably might not be able to afford that much to lose in a bet but a $0.7 is generally somehow small amount for a bet..
Hence, whenever a bet is taken consider the money gone until you eventually win it back with a return on it.. this is why it's advised to always bet what you can afford to lose ,so if he cannot afford to lose the $15 then he shouldn't, there's no point in taking the risk, although there are times the risk could be worht it yet we ought to gamble responsibly.
The house gets trickier on players in every moment of loss, accepting the money is gone should close up any expectations of winning more than the equivalent. Hoping to gain extra fund pins the player into further clicks and subsequent regrettable losses. Moreover, eventual wins arrives at a player's weak point, the toughest time to stop, for most gamers, the game will go on. In a nutshell, gamblers should take off the view of an unexpected win, and accept loss instead of risking money to grab wins.
But the thing is that it is extremely difficult for players to do this, to make this decision and move away from the game. The player simply does not want to accept this loss, he will be in a constantly bad mood, which he can take out on friends or family. Although I had the opposite reaction, after a big loss a long time ago, I stopped playing for a very long time and decided that I needed to learn how to earn money by working, I did not spare myself. And only after that I returned to the game, with a completely different perception, I no longer play gambling and I can easily stop at any time and it does not matter to me at all whether I win or lose. Of course, I no longer have the same bright emotions, but this allows me to make balanced and thoughtful decisions when required.
