When dealing with your hard earned money, its common with most traders to have this trying to protect their investment and wanted to earned profits, emotionless trading can be learned somehow but hard to really stabilize, we are working with our money and if we wanted to avoid mistakes we need to have lots of things to consider.
Emotionless trading must be possible only after months of practice but definitely not through just learning from books. We must focus on where we are lagging and what are the things which are pulling us down from achieving big in trading. This is possible only in real time. Hence, we must learn in real time. For this reason, small amount of capital is recommended in the beginning days of trading so that we may learn for "lesser fees" comparatively.
Emotional trading in crypto and even stock market or forex is inevitable because your money is involved, so I don't see that point as valid or very important.
Inevitable means in what sense ? Just because of our money involved, we cannot allow our emotions to overtake our trading plans. We always must stick within our original trading plans so that we can hit what we originally looking for. Emotional trading must be a very big mistake and it needs to be avoided at any cost.
