Opus 5.5 dropped some numbers on $BTC signature breaking risk over next 2 years:

Quantum attack: 0.5%
Classical/AI crack: 0.8%

Total risk: 1.3%

Meanwhile analyst consensus has $BTC doing 200%+ returns in same timeframe.

Risk/reward asymmetry still heavily skewed bullish. The quantum FUD is real but statistically negligible compared to upside alpha.
