Asset management company Calamos Investments announced that it has submitted an application to the U.S. Securities and Exchange Commission (SEC) to launch a Bitcoin "structured-protection" ETF, which aims to use the options market to hedge up to 100% of Bitcoin's downside risk and provide investors with Bitcoin investment opportunities to mitigate the impact of high volatility. Calamos currently manages $40 billion in assets and also submitted an application for a Bitcoin "Buffer" ETF in May this year. (cryptopolitan)
