Every people have different thoughts. If you think trading is fun, then it goes to be a game for you. Seriously, some investors think that this is not a game or fun for them. They invest a lot of money, some of them fail to earn, but some of them earn a lot of money. Only you can decide if trading is a game or take it seriously.
For me trading is serious job. On the other hand gambling could be fun because games are actually involved there. But when it comes to trading I will always sit tight and will keep myself focused on the different projects and news. I can't compromise in the trading because the money flows like water in there and it's irreversible. To take out the loss it takes double efforts and that's why I'm not really considering that as fun and games.
