blue dots are individual option buyer's profits.

European CALL / PUT options
BTCUSD price is $8300
Strike is $8300
Term: 30 days
Volume is 1 contract (5 BTC)

-	EUR BTC CALL	EUR BTC PUT
Premium	$7877	$1925

Personally, I can't believe the market will reach a consensus around premiums like these.

Summary:

• The Black-Scholes model is hardly suitable for BTC option premium calculation as BTC is a very trend asset
• Using BTC price distribution / Monte Carlo simulation we obtain contradictory results

My question is:
- how do you estimate a "fair" premium for a BTC option?
