Many posts discuss the possibility of exchange earnings with selling Bitcoin (and buy later). Other posts discuss the Bitcoin exchange rate, it seems that many agree there is a strong upward tendency and the volatility is hard to predict. It seems dat selling Bitcoin results in a serious probability of an opportunity loss. Selling Bitcoin can only be motivated by an (partial) exit. Do you agree?
I partially agree. As we all know, bitcoin's value is volatile and selling some of it can make you loose some opportunity as the value rises more, but on the other hand, there is also a possibility that the value will fall which will lead you to a great decision making for some reasons. In selling your bitcoin, you need to be smart and wise before making an action to prevent further disappointments.
