In real money trading that's called not having a positive expectancy but proceeding out of ignorance before the market gives you an education. I'm not a fan of the pay for sim gigs that are out there. But they could be useful to some by helping develop a profitable trading methodology while losing less than trading live. My issue is most people fail at trading long term due to lack of constraints and discipline. By using a paid sim service that forces their own constraints on you will more than likely severely limit the direction your own trading methodology can take.
I think the big thing is focus on your trading and what works for you. What others do is their business.
