What are OTC trading strategies for cryptocurrencies?

Could you elaborate on OTC trading strategies for cryptocurrencies? I'm particularly interested in understanding how these strategies differ from traditional exchange trading. What are some key considerations when engaging in OTC trades, such as determining fair market value, managing counterparty risk, and ensuring transaction security? Furthermore, are there any specific strategies that have proven effective in the cryptocurrency OTC market, such as leveraging market sentiment or executing trades during periods of high volatility? Lastly, how do OTC platforms ensure liquidity and facilitate the efficient execution of large trades? Thank you for your insights.
