Investment managers REX Shares and Tuttle Capital Management have launched two new exchange-traded funds (ETFs) that offer traders 200% exposure to Bitcoin's price volatility. The T-REX 2X Long Bitcoin Daily Target ETF and the T-REX 2X Inverse Bitcoin Daily Target ETF use financial derivatives to provide 2x leveraged or inverse exposure to Bitcoin, rather than holding the cryptocurrency directly. These ETFs join REX Shares' existing suite of T-REX products, which offer leveraged exposure to mega-cap tech stocks. However, a report by GSR Markets warns that leveraged ETFs often underperform relative to the underlying asset.
