The Swiss crypto investment firm 21Shares has launched two new exchange traded products (ETP) offering investors exposure to the largest cryptocurrencies — Bitcoin (BTC) and Ether (ETH) — while aiming to soften volatility via rebalancing assets to the U.S. dollar (USD). The new products, the 21Shares S&P Risk Controlled Bitcoin Index ETP and 21Shares S&P Risk Controlled Ethereum Index ETP, will start trading on the Swiss SIX Exchange on July 20. The ETPs will trade under tickers SPBTC and SPETH, the firm announced on Wednesday.
