I'm also more inclined that a person needs luck, and accurate mathematical calculation does not work with the crypto market,because it is very subject to manipulation, which is impossible to calculate
and the plot of the film is most likely fiction than reality,and if it is even possible that such math skills this is not for every person
It is obvious that you are not familiar with people who are obsessed with gambling. Almost everyone has their own system in which many factors are taken into account. Everything is built on numbers and mathematical calculations.
But anyway, if these are slot machines for example, then no matter how much you want, there are winning games, of course, there should be luck, but you need to think about everything correctly
And it seems to me that this very important skill will stop in time. I saw how people were either lucky or they really had some kind of their own system, but they won a lot of money. But they could not stop in time and lost everything.
