(Requires actually owning Bitcoin)

• You can still send and receive Bitcoin even if no one buys them.
• You can cryptographically sign messages.
• You can immortalise not censorable messages on the chain(Julian Assange proved he was alive like this)
• Becoming censorship resitant/ have un-confiscatable assets.

(Makes it more likely if you’ve been into Bitcoin)

• Learning about how to apply cryptography in practice.
• Run a node to learn more about computer science.
• Inspect the code/ processes to learn about how to handle production software well.
• Learning about P2P networks.
• Learning more about software engineering.
• Learning about game theory.
• Learning about economics and human nature.
• Learning how money functions.
• Understand why decentralization matters.
• Recognise the flaws in our current system.
• Meet amazing people who are withstanding the highest hostility possible, to keep freedom alive.
• Learn more about physics/ engineering to make mining more efficient/ utilise it differently.
• Recognize bs even faster

See even if this thing doesnt bring in any profits/ money, the value is infinite for people who use it correctly. This list can for sure grow a lot longer.

Now:

• How can you personally utilise gold without being a goldsmith, if no one accepts it anymore?
• How can you use fiat when no accepts it anymore?

You’re touching the non productive nature of money, without realising this applies to any monetary good, and Bitcoin might not even be bad compared to previous forms of money. The barrier to even understand Bitcoin is high for many people, once you really understand it, you’ll touch so many different fields, because it’s requires this to really get there.
