I feel that if an investor observes the regular market after investing and gets excited due to negative or positive changes in the market, he will never be able to hold his investment for a long time. A person is monitoring the market to invest continuously but if another investor checks after investing little by little how much profit or how much loss he has, but this will create obstacles in keeping his investment for a long time.
What you mean is that an investor after making an investment will be ready to sell his investment if he sees a positive or negative change in the market after regularly monitoring the market. No it is not correct at all because monitoring the market regularly does not mean that he cannot prolong the investment. Investors gradually become more experienced about the market as a result of regular market observation. There are many people who constantly monitor the market while investing, the main purpose of which is to see if the price of bitcoin has decreased in the market, if the price of bitcoin decreases, they will take the opportunity to buy more bitcoins during that dip.
Many also observe how much their invested portfolios grow as the value of Bitcoin increases. The Only possibility of people to check the market can only be to know when best to buy the dip just as you have explained. but aside that, I don't see reason why someone will be checking his portfolio how it grows when you have known within your mind the total asset you have and the equivalent value in respect to the current price of bitcoin at any given time. Checking the growth of portfolio should not even be considered since it's a long term investment. It sound somewhat childish to me. For me I don't see why we keep on emphasizing on the market fluctuations when we should be awear by now that the only reason for that is taken advantage of the dip to accumulate more.
