Yes.... I get your point their are those who bought Bitcoin when the price was up at $67k before the DIP happend and are even yet to sell these are real investors who knows how to control themselves from selling their Bitcoin much lower than what they bought.
They understand the essence of holding Bitcoin, it is for a long term no matter how long it takes never panic to sell.
It is even for Bitcoin to always hit a new All Time High after every halving so there will be every possibility of Bitcoin crossing above their entering price giving them good profits. Most of understands the market and at this very dip that happened bought even as to increase their profits and recover from the others.
The purpose of long term investing or holding is not to buy at a high price or an all-time high and then hold onto it and wait for the price to go higher. Those who bought Bitcoin at $67k entered at the wrong time, people were exiting the market and profits were being booked. They have no choice but to hold on to bitcoins as the price of bitcoins has fallen to around $15k. People who bought bitcoins in bear market will be able to make good profit in bull season and people who bought bitcoins $67k just waiting to cover their losses.
The aim of holding any coin is to get a good profit from it but the most important thing is to enter the coin at the right time. If we buy it at the right time, we will get good profit. A wrong time entry can never give us good returns no matter how long we hold it.
They don't have other option as they are not willing to accept that mistake and they will try to wait till the market move up
hoping that things will be okay instead of trying to short the market and take another risk, though some may doing liquidation while
the market is sowing some green, trying to minimize loses and plan to quit all the way.
