However, both can possibly happen in our lives when we can't control our gambling habit anymore. I prefer not the two but in this situation, I prefer to be just addicted rather than be greedy.
Gamble Responsibly...
I better not have myself into any one of the two cause the two are interrelated and being cognate it's a freeway to have the other if you already in chains of one. How do you think addiction starts with? It's a greed attracted attitude, the more a gambler gets greedy in going for more higher and higher stakes to win bigger money out of dissatisfaction of the little coming in, hence you're breeding gambling addiction. An endless urge for more.
I will prefer to be fond of a particular casino game or sports betting than wanting to either be greedy or addicted because none of the two habits is of anything good with gambling they are both bad entirely.
Gambling is a game that is full of risks, apart from being detrimental it can also damage your common sense which ultimately makes you greedy due to addiction. These two things are both bad and usually go hand in hand, if you become addicted it means there is greed and vice versa. Viewing gambling as a source of income or employment so that the addiction cannot be eliminated can lead to greed. The result will be suffering for yourself.
So if you ask, which greed and addiction will be a disaster? the answer is that both will lead you to disaster. It is important to control your emotions when gambling so that things like this can be avoided. If there are any signs that you are headed there, then you need to advise yourself. Because a responsible gambler is someone who can advise himself to gamble within his limits and not force himself on something he cannot control.
