I think it is also necessary to distinguish the timing. It can be sold at a good time. There is no need to last for a long time. There is no prescribed timeline. It is entirely up to you.
Only people who have a lot of money can hold it for the long term, for me bitcoin and crypto are short-term investments (less than 3 months), when I get the profit I want then I immediately sell it, moreover I'm still in college so there are many sudden needs.
It does not depend at all on the amount of money the investor has, but on his investment horizon and investment goals. I have been holding bitcoin since 2017 until now, since for me this is not the only investment and my investment horizon for bitcoin is about 10-15 years or the achievement of an investment goal.
