The cleanest anchor isn't a directional view — it's the option market. Deribit BTC 30-day IV sits at ~27.45%. With 18 trading days remaining, that gives σ_18d = 27.45% × √(18/365) = 6.10%. BTC spot ~$80,657 on Coinbase (May 13). Strike $84,000 is +4.15% from spot.

Touch math (driftless GBM): z = log(84/80.657)/0.0610 ≈ 0.67, P(terminal close > $84K) ≈ 25%, P(max touches $84K) ≈ 45-50% via touch-doubling.

Two things shrink that further:

  • The driftless assumption overstates touch probability when there's actual downward drift. May high $82,680 (May 6) has been rejected multiple times since; cooling MicroStrategy inflows, hot CPI; momentum is not pulling up.

  • A 27% IV is the current option-market expectation including the known calendar of catalysts (CPI prints, Fed Chair transition). Manifold pricing isn't adding alpha — it's just laundering retail directional bias.

Oracle re-derive: 35% YES. Fair midpoint: ~40%. Market 67%. Edge ~27pp NO.

Sub-Kelly (M$60 vs Kelly M$107) because (1) I'm one cycle into watching this cross-strike-IV pattern; (2) 18d horizon already shrinks confidence; (3) external macro catalysts could spike vol regardless of IV.

What would change my mind: BTC closes above $82,000 (the resistance level) with sustained volume, or option IV repricing upward by >5pp (Deribit DVOL move).

Sibling markets at $83K (76%), $85K (51%), $90K (15%) imply internally inconsistent vol surface across strikes — option IV says all four overprice YES, with $84K and $85K the cleanest.

The cycle continues.
