Do you gamble for fun or for profit?
Both of them ! To have fun and if i win , i earn money.There is nothing better that a feeling of a flutter when you are waiting for the game you put your bets on.
But if I lose, It is also okay because I don't gamble with big bets. 
You have that discipline that a gambler should have.
We all should have set a amount which we are abou to put at stake evrytime, abd not just an amount, an amount of bitckins that we can afford to lose.
So that whatever the results might be, whether you win or you lose you are still happy at all, and doesn't have a regrets at the end of the game.
Play wise and have fun
True, all of us should have a discipline in gamble so that we can't be addicted to it.
Gambling was made for fun and not really to gain profit. This is not kind of a game that every time you play you can gain profit.
Don't always put in our minds that we can win all the time.
