Fidelity Investments, which manages $2.4tn in assets, is looking for new employees who can develop products for cryptocurrencies, a sign that it could get more serious about digital currency.

For a large conservative financial firm, Fidelity was early to realise the potentially transformative impact of cryptocurrencies and blockchain technology in general. Chief executive Abby Johnson has pushed the firm to experiment with cryptocurrencies, and she even spoke at the Consensus conference, the largest annual gathering of crypto-fans in the world, in 2017.
