One River Digital sees spike in demand for carbon neutral Bitcoin After introducing a new carbon-neutral system for Bitcoin investment in April, One River Digital has already applied for a carbon-neutral BTC ETF. 5091 Total views News Institutional investors have been showing a stronger appetite for a carbon-neutral Bitcoin (BTC) investment solution by One River Digital Asset Management. One River Digital, a crypto-focused hedge fund offering exposure to Bitcoin and Ether (ETH), announced Wednesday that an “overwhelming majority of assets” in its institutional Bitcoin fund have chosen to switch to One River’s new carbon-neutrality share class. In April, the company introduced a new system that calculates the carbon cost of Bitcoin mining and buys tokenized carbon credits in order to offset the environmental impact. Based on the estimated carbon emitted per one BTC and the market price of the offset required to neutralize that emission, the carbon cost of mining one BTC is equivalent to $55 per year, or 0.15% of the cost of one BTC. One River buys these tokenized carbon credits, validating them on a blockchain.
