Nothing could be really trusted when the game is only based on pure luck, as stated no one knows the pattern and so when the time for crashing will come. Although some may say that there are ways to determine a pattern, I don’t think that it will be reliable at all.
When someone says that there's a pattern and he's certain with that. It is unlikely, if a game like crash has that pattern, it's just the mind of that person telling that there is.
Because what's certain is that it's a pure luck based game and you will never know until it crashes. And those people who have been winning are totally lucky and good to play the game.
