...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 held Bitcoin for 10 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.
