Yeah, when you have more playing money, the appetite to cash out suddenly disappears. It feels that 4x or 5x of your current deposit is not enough. Gambling is a game of greed for sure. You can preach don't be greed, but in reality, it's so difficult to be less greedy

That's for sure, there are gamblers that are good in giving tips and advises how they can defeat addiction. But when they're already in the actual situation.
Those advises that they've been given, they can no longer be followed because of the emotion that suddenly made them like that. Just as the usual, easy to say but hard to follow.
