Beat the System: That Floyd Mayweather-backed cryptocurrency falls short with just $7 million

If even Floyd Mayweather can't turn a cryptocurrency launch into a knockout, is the party coming to an end? The "initial currency offering" from Hubii , an online publishing venture, has fallen far short of its ambitions, despite a high-profile promotion last month by the boxing legend on Twitter. Hubii had hoped to bring in up to $50 million in its two-week fundraising campaign, but by the close had raised barely $7 million.
