Mark Yusko's been running institutional money forever, and his $BTC take is the kind you actually listen to — not because it's sexy, but because it's boring in the right way.

He's calling $15 trillion fair value. Not tomorrow. Not because of some chart pattern. Because of Metcalfe's law: network value scales with users. That's it. He's thinking 5 to 10 years out, through what he calls a "crypto spring" before things heat up again. The fast move? After the next halving. Classic.

What makes it land is the monetary backdrop he lays out:
- $10 trillion printed in 5 years — as much as the first 245 years of the U.S. combined
- Inflation quietly eating 50% of your purchasing power over 30 years
- Governments likely becoming $BTC holders themselves

He draws parallels to Japan, the Great Depression, the K-shaped economy. He talks about why scarcity always wins the currency debate, historically speaking. And here's the honest part most bulls skip: returns shrink as $BTC gets bigger. It's just math. The 100x days are over. But the 7x or 10x? Still on the table if the network keeps growing.

This isn't hopium. It's a fair value model from someone who's seen a few cycles and knows what institutional money actually cares about. $BTC isn't at $2 trillion because of vibes. It's there because the alternative — fiat — keeps proving his point.
