There is such a term as "forced investor", and it concerns precisely those people who did not guess the entry point when buying bitcoin and because of this they sit and wait for the price to at least return to their initial entry point, for example 120,000, so that they can simply sell bitcoins and regain their funds. And this is a very bad situation in which a person is mentally exhausted and at the same time he is not a full-fledged investor.
But if he had bought in stages, as the DCA strategy advises, this would never have happened to him, because he would have distributed his buying points in bitcoin over time, which would have caused the price to constantly average, and he would have felt like a truly free investor who was moving towards accumulating bitcoin, and would not have been sad looking at his an unprofitable position.
Your forced investor concept may be useful in explaining some situations, but I wouldnt take it as the main explanation for the Bitcoin investors problem. Suppose a person bought Bitcoin for $120k at once and now the price has gone down. If he is just waiting for $120k to come back. He can sell it at $120k and get his dollars back, then the first question that comes to mind is what was his real goal? To accumulate Bitcoin, or to take a price trade and take a fiat profit?
For a long-term investor, his initial entry price is not supposed to be an exit line. The focus of the investment is more on how much Bitcoin is being accumulated, depending on how sustainably he is buying according to his cashflow.
Now, lets talk about DCA.
Yes, if a person had bought over time without pouring the entire available amount into $120k, subsequent purchases could have reduced his average acquisition cost as the price went down. This is a practical benefit of DCA. Suppose he bought regularly at $120k, $100k, $105k and $90k. His average cost has come down, but if BTC is at $70k, he may still be in unrealized loss. Here it is understood that dca does not stop the risk of loss or completely eliminate it. A single entry point reduces the need to guess correctly and helps in accumulation over a long period of time. So if you bought at $120k and today your only thought is, When will it be $120k so that I can get out?, then maybe the real problem is in the mindset. This cannot be an investment in any way, it is a trading type mindset.
