i dont think we have a strategy or idea to make our bet is safe, its all depends on our lucky
even you have awesome strategy but tou have bad lucky you will get lose
There is no such thing called a safe bet or investment in this world and everything comes with some risks. This gambling is made for having just fun so you should worry so much about the strategy or method instead just spend some of your free time to enjoy the games with little money and if you're lucky then you will surely win money otherwise just enjoyment.
