Statistically speaking, it is almost impossible to double all savings for gambling, but it is likely to lose all of them. The design of gambling activities is inherently beneficial to the casino/dealer, which is called the "dealer advantage". In the long run, people who participate in gambling will lose money on average, rather than making a profit. In addition, gambling may also lead to: -Serious financial problems -Mental health issues -Gambling addiction -Harm to personal and family relationships If you are considering how to increase your savings, I suggest seeking formal financial advice, such as sound investment, savings plans and other more reliable methods. If you are troubled by gambling, you can also seek professional psychological counseling.
