It just depends on the ability of certain traders. If they want to do day-trading then do it, you shouldn't let people like this tell what to do and tell em to avoid certain thing. If you are capable to do day-trading and know the risk of this type of trading, then you should go for it maybe you will earn something from it. I just hate it when people say, please stop doing this and then do this, where they don't even give the correct reason of this.
