Thematic ETFs, including those focused on digital assets and crypto-mining operations, have been among the casualties of the changing market environment in 2022. At least two crypto-focused funds, including the Volt Crypto Industry Revolution and Tech ETF and the Viridi Bitcoin Miners ETF, have been shuttered. Additionally, the VanEck Digital Assets Mining is the decentralized process by which new coins are entered into circulation in the cryptocurrency world. It involves solving complex mathematical problems using computational power. Miners validate and record transactions on the blockchain and are rewarded with newly minted coins. More ETF has also been approved for liquidation.
