7RCC Global has launched BTCK, an exchange-traded fund (ETF) that combines 80% bitcoin exposure with 20% regulated carbon credit futures. The fund gives investors a listed product that blends digital assets with environmental commodities. 7RCC Global has brought one of the crypto market’s earliest ESG-linked bitcoin ETF concepts to public trading. The firm said this week that its 7RCC Spot Bitcoin and Carbon Credit Futures ETF has started trading on NYSE Arca under the ticker BTCK.
