Why is it best to only hold one position?
1. If we are looking for a strong target, we should look for the strongest one currently on the market. Rely on your own vision to find the strongest and most likely target. If there are two strong ones, choose the one that is more suitable.
2. When BTC rises, "not necessarily" every one will rise, some will rise, some will fall, and some will even remain unchanged. When the market falls, every stock will "certainly" fall, and it will fall sharply, so you will have to stop the loss or force the position to close. There may be a few stocks that resist the fall or rise slightly, but basically there is still a death rate of 80 or 90%. If you hold multiple positions, you will almost always lose as many as you have. If you only hold one forever, you will only lose one at this time.
3. Opening multiple positions is a bit like gambling on roulette in a casino. If you buy black 7 and red 13, if the market falls, it will be green 0. You always have a chance of being killed. Of course, the assumption here is to never go short.
