If you don't want to lose and lose in gambling then you can choose not to gamble, or try other alternatives such as just for entertainment by using a demo account. But even if at first you only use a demo account which gives easy wins, you can be motivated to start making deposits assuming the wins you get on the demo account will continue when using real money. So, gambling itself is difficult but if you don't have the target to win big, then you also won't waste your time and you stay in control of the game.
I think when gambling using a demo account in my opinion it is not too valuable because it will only be a waste of time, a demo account should only be used for learning and actually gambling places will never be able to guarantee a profit because when gambling there will be potential losses. therefore if as a gambler it is better to keep gambling with small values in the hope of getting big profits.
Valid point. For those people who want to gamble and earn at the same time, using demo account or fake money in gambling certainly don't makes any sense. It will just be a waste of time and effort for them because they are after the gain from it. And if they won't use real money, there are definitely no returns for them. Hence, opting for using real money is a better option if they really want to risk. Meanwhile, if someone is just a newbie and just wants to check and learn how gambling works, then demo account or fake money might be a good option.
Fake money and demo accounts are good for newbies for them to practice without losing anything. They will learn the do's and don'ts of gambling without sacrificing anything yet. After learning the basics, they can eventually start betting with real account using real money with small bets for starters to actually practice what they have learned. And of course, if their goal is to really earn, they'll have to transition eventually. They can't play using fake money and demo accounts and expect a profit afterwards. After all, gambling is also taking a risk. You win some, you lose some. High risk, high reward.
