Announcing the completion of US$75 million Series C round of funding for the digital currency platform, Coinbase has set a new record in the Bitcoin world for the largest amount of venture capital invested in a digital currency startup. More importantly though, the range of investors putting money into the company now extends beyond the tech-centric firms, such as Lightspeed Venture Partners and Bitcoin-specific groups, such as Crypto Currency Partners. The addition of USAA Bank, the investment arm of the American Insurance giant, and the New York Stock Exchange itself, will make many critics of Bitcoin, and investors previously wary of the digital currency world, re-evaluate their positions.
