I don't agree with the 3rd one. I'm actually doing this. I deposit a small amount not only for fun but also for profit if I am lucky, and if I lose this amount, I stop, then do it again on the next day.
I've heard different statements concerning gambling being for fun and entertainment, if the OP thinks gambling was meant for the rich only does it mean that the rich class are the only ones entitled to that aspect of fun and entertainment? That's what got into my head immediately I read that third line and I disagree with it, cause I've seen where someone used a little amount of money to make huge profit, I know it doesn't occurs on a regular but then that's where luck comes in.
Gambling is not basically for the rich, any class can partake in it but must do it responsibly, one of the ways involves gambling with spare cash, a rich man's spare cash can be $2k or $20k depending on how wealthy the person is and poor man's could be $2 or $20 either ways, both parties would depend on luck mostly and good gambling skills to won their bets, it's not the amount of money one bet with that determines whether they'll win or not.
Yes, rich people can afford to gamble with large sums, but this does not mean that their gambling is more justified or "correct". Like anyone else, they can experience good or bad luck. The problem is that for people with limited funds, losing even a small amount can lead to serious financial consequences, so it is important to realize that bets should only be made with free money that a person can afford to lose.
