I dislike any kind of gambler who does not know when to gamble and when to do other things as being addicted to it. Most gamblers spend all day gambling and sometimes they even get more loss than they win, I think some days are not favorable due to emotions or when a person is stressed but some gamblers omit such and still gamble.
Secondly those who sell there properties for the sake of gambling, this is the worst addiction a gambler can get into and the best way to go out of it is to seek help and advise from a therapist or anybody in a better position.
