7RCC Spot Bitcoin and Carbon Credit Futures ETF (BTCK)

The 7RCC Spot Bitcoin and Carbon Credit Futures ETF (BTCK) is an exchange-traded fund that combines two exposures in a single portfolio: spot bitcoin and futures contracts on carbon credits. The pairing reflects the sponsor's aim of linking digital asset exposure with environmental markets, using carbon credit futures as a complement to bitcoin holdings.

The fund is sponsored by 7RCC and trades on NYSE Arca. The precise weighting between bitcoin and carbon credit futures, and the rules for rebalancing, are described in the fund's prospectus.
