deep-OTM puts vs calls

What the positioning says

●Bullish positioning: only 0.23 puts per call outstanding.
●Call wall at $110 (10k contracts), 9% above spot — the upside strike the crowd is already parked on; often acts as near-term resistance.
●Put wall at $70 (2k contracts), 31% below spot — the hedge floor; often acts as support.
●30-day ATM implied volatility is 80% — the market prices very large moves; option premium is expensive.
