There’s no way an hodler will continue to hold forever even when they know they’re in profit. A time will come that they’ll be willing to sell some part of the investment even if not all of them. The reason for investment it to earn profit, it will be meaningless to just invest and not take profit after you’ve actually gotten enough to take some profits and still continue with the investment. Bitcoin has already shown to many that it’s an asset that will continue to have value, so they don’t get themselves stuck to panic and fear of losing their investment in the future.
I think almost all investors have their own selling targets. This means that everyone who invests in Bitcoin will have a price target to sell in future. It will Only a few will continue accumulating without any plan to sell at a specific price target. However, I believe a time will come when even those who initially did not have a selling target will start selling because we can't hold it forever. Our old age might also lead us to sell. It is also possible that some people may choose not to sell, allowing their children to inherit their Bitcoin investments instead.
