For sure! - Especially if living beings depends on you.
I don't personally think that it's only about greed, it's also about the excitement and to not feel like a loser. I know that feel because it is practically the same in some videogames for me. Especially MMOs that are cool with challenging bosses or pvp.
People for sure needs to regulate the money they spend daily just like i need to regulate the time i spend daily on the same things or the aforementioned videogames.
this market even you are losing some and also times got something to win then you are always be in a good position not being over gambled, its
about controlling your emotions to stay safe.
