Since I began trading, I have never made a profit, but I believe this is because I always sell off as soon as I notice that the amount I purchased is declining and not returning; perhaps in a few days, I will be afraid not to lose all the money, so I will then sell off.
The advice you are giving has caught my attention because I have read a lot of articles about long-term investments, which I am currently involved in. However, I am concerned that this bear market will continue for a long time because, in my opinion, it should have ended by now and we should be expecting another January, but it has been around for almost a year now, which is definitely making me nervous.
