Bitcoin & USD are both tools to capture & transfer optionality.
The ability to exercise that optionality in the future is why we save in the first place. Noone knows exactly what their future needs or desires will be.
Bitcoin's USD price is the scoreboard for bitcoin's optionality level. It's the strongest & most accepted monetary unit in the world today. You don't have to like it, but it's our current reality.
I'd prefer Lyn's honesty to this virtue signalling crap that people repeat about never selling their bitcoin. When you buy a coffee with sats, you're also selling bitcoin.
