Xapo, a new bitcoin company that offers secure ways to store the currency as well as a bitcoin debit card, has raised a new $20 million investment. The investment, led by Greylock Partners and Index Ventures, brings the company’s total funding to $40 million — all announced within the last four months. In April, repeat entrepreneur and Xapo CEO Wences Casares sat down with Kara Swisher to discuss Xapo’s security features and the overall bitcoin phenomenon.
