I enjoy playing and go into it with the knowledge the I very likely will loose, but it's entertainment.
If you are looking at it as an investment of time and the reward you get for that time...nothing on steem is worth the time currently. At that none of your time messing around online is worth it, no time on FB is worth it, watching YouTube isn't worth it, and for sure watching TV isn't worth it either. I know people that pay $150 a month for TV and spend hours a day watching it...what do they get out of that? Well it's all a form of entertainment, it's not about getting anything other then that entertainment value in exchange for our time.
For entertainment it's cheap. A really bad day of playing might cost me $40, but that rarely happens and as I've shown over time it levels out. But even at $40, compared to the potential losses if I went to a real casino that is nothing. Haven't walked into a physical casino since I started playing dice and BJ online as it fills the same entertainment value but with very little risk. Heck I spend more then $40 on drinks at the casino and gas/tolls to get to the casino anytime I go.
But if it's not something you enjoy then it's not for you that's cool. I'm having fun and will keep doing it even if it's not a smart use of my time.
