In such a volatile market as cryptocurrency, I have heard many people stress the importance of taking profits. For example, when a coin doubles in value, they sell 50% of their holding. This ensures profitability (if a coin goes up) but results in the investor missing the peak. I was wondering, could stop orders be better?
For example, if each time a coin goes up 10%, an investor sets a stop order at 90-95% of the present value. That way, there is no sale if it keeps going up, and if it plummets, it ensures that you sell it close to the peak (90-95% of it). I never read about something like this online. What are some flaws with this strategy / thinking?
