I agree, but on the other hand, I don't actually blame them. I say that because this market is just so hard to read that even seasoned and long-time traders just find it hard to infer how the market would unfold and so as its assets. Therefore, I think that the reality is that one should really be careful with his dealings because the fact of the matter is, even if sometimes, you prepared for your ventures, it can still be susceptible to going south because the market is just so volatile and unpredictable sometimes. Thus, to answer the question, I think the biggest mistake one can do is to just wing it and not prepare.
