I'm not selling anymore if I'm losing, because if I sell - nothing will change, but there is a chance that something good might happen and I will be able to minimize my losses. But now I'm always prepared to lose everything I put on something, but the chances are better if this is not the only project I am involved in.
a good trader will find it difficult to believe the depreciation will not stop. one will keep expecting that since it wont pay to lose as the value starts decreasing it wont soon rise back maybe until it totally crashes. apart from speculation & business skill ,wisdom is really exoedient. to know when to withdraw.
