Price fluctuations will require adjustments when buying and selling. So, when the price has risen significantly but in reality or subsequently stabilizes at that level, you can buy with the expectation and expectation that the price will rise again sometime in the future. However, when market sentiment is unhealthy, you should refrain from buying hastily, as a price drop after a purchase will require more time to profit.
Smart investors successfully use the period of price fluctuations. One use of this is to regularly run Bitcoin accumulation in the DCA method. They do not need to adjust the buying price, it adjusts automatically.
I think that most of the investors that are getting all worked out about when the best time to buy bitcoin is and wether or not it is still advisable to continue buying bitcoin have either been told that bitcoin will guarantee them an incredible profit and the eagerness to see profitability happening too soon always push them into trying to over analyze the market.
If you are an investor that is more after how soon you can reach your investment goal and that is staying focus of taking advantage of the current buying opportunity, selling would never come to mind at this point in time but rather, your interest will be that you want to be able to stack as much bitcoin as you can while you still have the time. the conclusion that bitcoin would not disappear in the next four years and counting is enough to remain consistent at your buys regardless of current market sentiment.
