Backed by Andreessen Horowitz, RRE Ventures, and Qualcomm, 21 has just raised $116m - the largest round in venture funding received by a cryptocurrency startup.

But according to Marc Andreessen, 21 is on a path to develop the "core infrastructure for mainstreaming bitcoin." With Qualcomm's support, is it possible that the crypto startup is targeting the massive potential of the Internet of Things?
