Investment firm Roundhill Investments has announced the official launch of the Roundhill Bitcoin Covered Call Strategy ETF (YBTC) and it will begin trading on CBOE BZX today. This fund is also the first bitcoin-covered call strategy ETF listed in the United States, aiming to provide investors with bitcoin investment opportunities while also providing risk exposure to bitcoin price changes (limited by the upper limit). It should be noted that the fund does not directly invest in bitcoin, but provides price return exposure to exchange-traded funds primarily invested in bitcoin futures contracts.
