...Imagine a person who purchased BTC in 2011 and held it for 13 years, his profit from this investment is huge. Now think you are that person in 2035, you can calculate the profit margin and this will help you calm your nerves.
It is very difficult for me to imagine such investors who have hold Bitcoin for 13 years. Who are these people who resisted the temptation to sell their coins when the price increased by tens of thousands of percent? I would never become one of them, since I can't hold my coins so tightly.
Although sometimes there are a small number of us who are able to hold on to their Bitcoin for quite a long period of time, perhaps you could say that they have completely forgotten about their Bitcoin investment so they are not tempted to sell it when the price starts to slowly rise until it reaches ATH, I personally also can't hold onto it. Bitcoin for a period of 13 years without touching it at all, a few years ago I tried not to touch my Bitcoin holdings for a period of 2 years but unfortunately every time I saw the price of bitcoin increasing then I was always tempted to sell it to make a profit.
