There's no work method that will guarantee you prifits in the long run as a gambler. Whatever strategy that you come up with can only work for you temporarily. Whoever claims to have such strategy that can generate profits in gambling, is only deceiving himself and whoever falls for his lies.
Gambling isn't a skill, therefore, only luck can fetch you profits but it comes by chance. Don't have the mindset that people can make profits from gambling, if not you will fall victim to scammers.
Most gamblers are not Patient enough to know of their strategy works on a long term base, they assume they it's something that they can always get correctly because they have won one or two times.. winning strategies can only be temporary, there's absolutely nothing that can work over a long period of time.. people who come up with strategies think that they are the first to think of such, any idea that comes into your mind now has already been explored by someone in the past... there are no ways to get around gambling to make consistent profit.
