Brian Armstrong :

“I think Bitcoin could reach $BTC by ~2030 based on current conditions and progress.
Think long-term.
Then I see people saying $1MBTC is “mathematically impossible” because it would require $15Tof inflows.
this is where the argument gets interesting.
BTC does not need $15Tof fresh money to create 15T+ of market cap.
market cap ≠ money invested.
price is set at the margin.
if liquidity gets tighter, institutions keep accumulating and demand keeps growing, a relatively small amount of new capital can reprice the entire supply much higher.
does that mean $1MBTC by 2030 is guaranteed? obviously not.
but calling it “mathematically impossible” because the required market cap is 20T-ish misses how markets actually work.
I’d rather bet on the math of supply + demand than a simple “market cap = capital inflow” equation.
