CoinShares' WGMI, a cryptocurrency mining ETF, has experienced a significant downturn, recording a 43% drop this year, as reported by CoinDesk. This makes it one of the worst-performing ETFs in the market. Why the WGMI ETF is Declining WGMI's portfolio is heavily invested in cryptocurrency mining stocks. The recent price declines of key holdings like Iris Energy (IREN), Core Scientific (CORZ), and Cipher Mining (CIFR), which fell between 42% and 52%, have significantly impacted the ETF's overall performance. These companies face challenges like rising energy costs, increased mining difficulty, and fluctuating cryptocurrency prices, leading to reduced profitability and investor confidence. The correlation between these individual stock declines and WGMI's overall drop highlights the risk associated with sector-specific ETFs. ```
