i agree with this, the only problem is when is the correct time to exit, you will learn it by losing, at least at the beginning
There is no "correct" time to exit this. Basically anytime you got a slight profit about 1 % then that would already be the best time for you to exit thus in theory people are always willing to stay up longer in hope to get much more which actually ends up burning themselves instead.
Thus Of course with a solid investment such as gold and/or real estate / BTC people tend to stay much longer though since it is meant to stay as a long term investment
correct in the sense of maximizing your profit, and minimize the damage from the fees, if you can alwasy exit at the correct time, your final income would be higher, so it's an important aspect
Indeed I has stated that it has no correct time as there are several aspect to look at and thats depends on each individual as well. Sense of maximizing profit and minimizing risk will be different somewhat one across another and not to mention that no every investment would be the same in this case.
Therefore there is no "correct time" on it because discussing about this will lead to an endless discussion because each person will have a very very different opinion onto this
