The way people play in a game can be affected by the buy-in amount. In general, players may be more cautious and conservative with a larger buy-in, as there is more at stake. Conversely, players may be more willing to take risks and play more aggressively with a smaller buy-in. This is not a definitive rule, and there are many other factors that can influence how someone plays in a game. Additionally, many players tend to use all-in strategies more often in low buy-in games. The idea is that if they lose, they haven't invested too much, and if they win, they can multiply their initial investment.
