I'm slowly changing my views on gambling recently. There is of course no safe method to gambling. You have a higher percentage of success and can even profit from it in the long run, if you choose sports betting or poker, but if you go for casino games, then it's o course all luck.
The thing is, and that is what I'm changing now, although there are no strategies for casino, because you just can't beat the house edge, there are betting systems or progressive betting systems that can help you in the short term, and will limit your losses if you are losing, and escale your profits if you are lucky, and that is exactly what you want when you are gambling in casinos.
So instead of wasting time in strategies to beat the house edge, spend some time creating a betting plan to boost winnings and limit losses. Like you normally do in the trade market.
And just to be clear, you will lose in the log turn, but can boost profit in short term if you are lucky.
Why not instead shift your attention to betting on odds, and more predictable outcomes? Nothing based purely on chance; look for sports betting and professional poker. Although there is still an element of luck, you can add your skill to the equation and you'll generally have a happier time with it. It'll also be more fun than relying solely on luck and possibly losing.
