It's for them to experience that, if they're not going to notice the risk that they will take, it could pay them a lot.
Those that are not used to futures much better not to get involved on it. Or if they want to try, just do it as if you're gonna lose the money no matter what happens.
I do agree that a bit more "laissez faire" approach is not really bad for people to learn, if we keep on interrupting them and telling them what to do, they will not know why they are not doing something, they would be not doing it just because we told them to, and they would always have that "maybe it could work" mindset at the side of their brain. However, if we let them do whatever they want, then the yare going to test and learn why it's a bad idea themselves and that's an important learning opportunity for them.
I would say that the best thing about this would be just making sure that they are making a profit based on what they are approaching it like, and that is not a bad idea at all, it would give them a chance to learn. Learning all by yourself and gaining experience is the best way to make money, and I believe that if we are going to end up with something big about this, then we are going to end up with a result that should be very important in the end.
Like the other people believes about experiencing something to tell whether it's worth it or not, let them be.
Those that learns from the advise of the experience of others are paying them well. And those that are adventurous and don't like to just learn it from the others but also from themselves will have to see it and they will react on it accordingly.
