I agree with luckmcfly as it is true that poker players are mostly big money holders who necer quit even though they lose so much in the process of playing but then most of them always run bankrupt due to excessive playing and always trying to recover from previous losses.
I think one of the reasons why most of this gamblers do end up being bankrupt is because of so much addiction which would be eaten them to the core. Poker game is much of addiction and if we are not that careful then we can end up been a addictive which can as well make us go bankrupt one day. Excess bettings have there own detriment.
