Black-Scholes Model Failure

Assumption

The Black-Scholes model operates on several core assumptions that frequently fail in cryptocurrency markets, most notably the premise of continuous trading and log-normal price distribution. The model assumes volatility is constant over the option’s life and that asset prices move smoothly, which contradicts the observed high-frequency volatility clusters and fat tails present in crypto price data. Furthermore, the model assumes no transaction costs or market friction, which is highly unrealistic in decentralized finance environments.
