How do you explain your reason for HODL to someone uneducated in BTC?

“At what price will you sell your Bitcoin?” “What is the end goal then, if you don’t ever sell it?”

I’d consider myself to be fairly well educated in Bitcoin (thanks Saifedean), but I often struggle to give a concise answer to a very common question I get, when discussing with friends who have no / limited knowledge of it.

I know my reasons and I can go into reasonable depth about them, but I feel like I lose people’s attention by going into rabbit holes. At the same time, I don’t feel like “I believe in it as a store of value” (for example) is enough to qualify my thoughts.

I’d be interested to hear what people say when discussing with a layman about this sort of question.
