The move amid reports that institutional investors have supplanted individuals as the top bitcoin traders. : Fidelity Investments is launching a new company for institutional clients that will trade and store cryptocurrency assets such as bitcoin and ethereum, the mutual-fund company announced Monday. The new company, named Fidelity Digital Asset Services, will not set up an exchange to trade cryptocurrency assets, but will connect with a number of other crypto exchanges to help its clients quickly find the best price. Fidelity will also store the private keys that control cryptocurrencies with a combination of enterprise software and vaulted cold storage.
