The 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, aimed at hedging up to 100% of Bitcoin's downside risk through the options market, providing investors with a Bitcoin investment opportunity to mitigate the impact of high volatility. Calamos currently has assets under management of $40 billion and submitted an application for a 'buffer' ETF for Bitcoin in May of this year. (cryptopolitan)
