Oh boy.
I remember when I believed in this stuff and thought that roulette was infinite money. I think that everyone goes through this phase one way or another.
I think that others have already said enough about this being a scam/fraud, and that is completely right. Let me just say, OP please don't see gambling as a way to make money. It's pure entertainment.
Having strategy doesnt always imply that you are after on making money or making it as an income because there are people whom do really play and make use of it to prolong and
do enjoy the game a little bit longer.When it comes to roulette strats then there are some examples.
Martingale
Fibonacci
D’Alembert
Paroli
Labouchere
Parlay
We can test out these strats but doesnt indicate nor assure about winning.Its all random!
