So, if a strategy is being sold for games like poker and blackjack, then it's still a bit good, but on the other hand, I guess another question would be, what is the seller still goes ahead to sell same strategy to other gamblers as well, which i sure trust he or she will as long as it's money we are talking about, this also will completely destroy the whole strategy, so, in the end, we still discover that its a very foolish decision to pay for strategy to win games, be it luck dependent games or skill or knowledge dependent games, for luck dependent game has no other strategy of winning aside luck, and this i believe is also same for knowledge based games as well.
People who sell books that teach plebs about "winning" in gambling and/or sell videos and other forms of learning materials are probably not winners in the thing they teach as well. Or the thing they teach probably was profitable before, but stopped being that and the only way to make profit from it is to sell it.
The actual winners will never share their secrets.
You would really be having that kind of thinking or realizations on the time that you have think up well on which if they were really that profitable then they wont really be selling ebooks at the first place.
This is why it would really be better that you should really know on what you are really dealing with and it would be better that you would really be creating the strategies that you could really be able to make and not really that tending to pay up something which you could really actually use it for free. You could really see tons of strategies online and it would really be just that depends on you on what you would really gonna use. There are ones who are really that thinking that this could really put them at advantage or having that sure win thinking without even trying out to realize that these things are created for the sake of prolonging and enjoying the game and not to make money.
