No pain no gain !
Even if you gamble with care, you still able to loss or just make small profit.
I'm suggest if you want to gamble just make sure that you're prepare for lossing rather than winning !
There is no way for betting safe in a gamble,if you wins you can make more money or it will be your fatal bro.
But there are some ways available for not losing your all investment.Make sure you have time and money limit on gambling to reduce yiur losses in gambling.
When we do talk about safe then its 100% winning rate but when we do talk about being safe on getting wrecked then it is possible but would depend on the steps and limitations that you would made.First bets wont be guaranteed to be safe on losing but yet we can make our self safe on possible addiction that it would gives. Safe is never been suited on the field of gambling.We would really be destined to lose money if you cant afford to lose money then better not to engage on it on the very first place.
