I don't think ppl realize how "diamond hands" came about.
Those are the HODLers that took the mantra "Hold On for Dear Life" to not only for their Bitcoin but for everything of value: Life, Family, Time, Prosperity, Security, Ethics, Morality, etc.
This comes with not only time in market but taking the time and doing the work to learn about Bitcoin.
Asking questions: Who, What, When, Where, and Why?
The answers to these questions are personal and with that, Bitcoin takes not only a "financial" purpose but a personal purpose.
When Bitcoin becomes personal, Bitcoin becomes truly valuable and you never want to let go. Then you earn your "diamond hands."
