Buying during the decline and selling after the decline is over will never be right. Because an investor should always keep his investment in mind for the long term. As you said, an investor loses more by doing so. Because we can never tell what will happen in the future. There are many businesses who buy with a lot of money during the decline and after a while after the decline when they see that the market has fallen again and their investment is losing money, they panic and sell their investment and they lose a lot of money. This should never be done, one should always continue to invest in a long term and should continue to buy continuously.
If a person waits for the decline, then he can miss many buying opportunities. Many times it is seen that the decline does not happen according to their expectations and then they regret a lot why they did not buy then. So this should never be done, a person should always invest in a long term and should continue to buy continuously by adopting the DCA method
Since the beginning of creation, people's regrets today and in the future will never end. People regret every moment. It is a natural characteristic of humans to regret that matter only if they do not make a profit. We ourselves also regret at different times. Regretting investing in Bitcoin has become a very common thing. While there is time, they will sit and wait for a fall without investing and if the fall is long, they will withdraw their investment for fear of losing money and they will regret it after a few days when the price increases. I think this is a natural cycle. All investors know that we should not wait to invest in Bitcoin. But there are some traders called investors who make losses every time but cannot learn from it.
Here you say "you should not buy during the fall" This is not entirely true. Rather, you should buy in all situations, no matter what the price of Bitcoin is. I say that if you find a fall in the market, try to invest more. But you should not sell as soon as the fall is over. Because I know that no matter how big a fall Bitcoin gets, it will recover over time. If you are calculating an investment for a cycle of 4-6 years, you will definitely benefit. Because no matter how much the price drops, a new ATH will occur in the price after a cycle.
