Matt Kaufman, Head of ETFs at US asset management firm Calamos Investments, stated, "With over $1 billion flowing out of spot Bitcoin ETFs last week, investors are moving funds into Bitcoin products with built-in protections against downside risk." According to CoinDesk, he explained, "Interest in Bitcoin strategies that reduce volatility and downside risk is growing. Our protected Bitcoin ETF invests approximately 90% of its assets in Treasury bonds to counter downside risk." He added, "Previously, the focus was solely on whether Bitcoin qualified for portfolio inclusion, whereas now, there's growing interest in how to utilize cryptocurrency investments to improve risk-adjusted returns and portfolio construction. It's evolving beyond the scope of simple spot investment."
