Of course, it is a superstition plus luck.
I have some friends who bet for the first time and won huge during their beginner's betting, that's why we called it "beginner's luck" but still it will not apply to all. Luck is still your friend here even you are beginner or not.
If they consider their trading as betting, they will lose money with their bets. Because luck won't stay with them forever, so no matter how much profit they got from "Beginners' luck", they will lose big later, all profit from "Beginner's luck" and even more including their initial capital.
The worst effects from trading with pure luck is they will act like gamblers, no strategy, no cut-loss order setup, no aware of risk from altcoins and trading with altcoins. Sometimes if they pick terrible altcoins, trading with them will be like suicides.
