Why wouldn't we though? I understand most people say its about money, and they are right its about trying to make more money, but also its not unethical thing, its not immoral, its not illegal, so why shouldn't we do something like this if we just want to? We can literally do it for fun, so there is really nothing to worry about when you are trading. If we can do this then there is really nothing to care, and we are free to do whatever we want. I understand there are some issues at times, but this doesn't really feel like we are talking about a thing that takes time, we can assume this is a good thing.
