One of the biggest mistakes a gambler can do is to compare their wager to the the wager of other gamblers to be honest, and the are games which e courage small gamblers to risk more than they initially planned, Crash/Aviator games are a good example of it, since each gambler can visualize the wager of others, it can be very tempting to be assume those who heavily gamble in st very specific moments have some "knowledge" on whether the next crash multiplier would be a long one or now.
I also avoid to see the section of "big gamblers" or "big bettors" on casinos. To each their own and with their own financial capacity
You're right and sometimes those kinds of comparisons arise without looking for them, and of course the differences are abysmal, the games you mention, especially Crash, are one of the ones that most awaken that desire to win, in fact when I used to play Crash a lot I only thought about winning, I never thought about losing, sometimes I abused it, because x2 is enough to win something, I put x3, x5 and of course I lost, but I saw that some players in the historicals won with those multipliers, everything seems great except for one lol, I think that has happened to many.
