for me I know that the best time to make a profit for buying and selling of Bitcoin is when you have a target of when you buy from them and make a profit so the best opportunity for me is one an investor to purchase exactly when the price of Bitcoin is going very dip so that when you purchase within interval of this month the most to be a change in the market so that when you said you can update make a proper profit from your investment.
setting of target while you're buying your Bitcoin is so essential that it's what determines when you should or shouldn't sell your Bitcoin regardless of your current profit status in your Bitcoin investments journey. Part of the reason why some people are eager to sell their Bitcoin whenever they are in the slightest profit or when they experience some DIP that's taking longer before it gets back to becoming bullish is that they are just buying and don't have a target they are hoping to get to for a particular time frame.
Setting target shouldn't be more of trying to set a range of value that you would want to buy and another range of value that you wouldn't buy. It rather involves setting an amount like getting to $40k before the end of a circle which will make you break down your target into a one year plan and then a one month plan and possibly a weekly plan and what will aid you to carry out this plan and effectively reach your target would be to follow up with your accumilation with the use of the DCA method which obviously is the surest way that will help you to reach your target the way you've set it out.
The interesting thing with setting targets is that it gives us investment discipline, which prevents us from taking certain decisions that would affect our investment along the line. Most people are not disciplined enough, thereby allowing bad Market condition to pressure them into selling even when they don't plan on selling. And also, setting our target also teaches us on when to enter and exit the market, so we don't incur heavy losses at the end.
