If crypto assets really are the "Craziest Bubble Ever," then Naval Ravikant is the movement's elder statesman. The founder of AngelList, Ravikant didn't talk much about startups in 2017, instead preaching the gospel of the ICO on Twitter in 140-character bursts that were part roadmap and part prophecy for a burgeoning industry. In the process, he helped open doors for a new wave of innovative cryptocurrency projects, giving a vital boost to an industry that had all but been locked out of Silicon Valley following bitcoin's 2015 correction.

Part sheriff? Part outlaw? Either way, Joe Lubin appears right at home in the "Wild West" of cryptocurrencies. The leader of a company that's part ethereum project incubator, part change-the-world commune, Lubin showed no shortage of influence in 2017, launching some of the first successful ethereum tokens and winning over countless enterprises to the platform. If Vitalik envisioned the new world, Joe Lubin just might be colonizing it.

Call it the biggest short in history. China took plenty of actions against cryptocurrencies in 2017, banning ICOs, shutting down domestic exchanges and all but taking a match to what was once one of the industry's largest and most thriving ecosystems. But if China is setting a course apart from the world, Yao Qian may be its biggest asset. The man in charge of rethinking bitcoin on behalf of the world's largest state isn't just empowered, he seems to know crypto inside and out.

Speak softly and carry a big SegWit? If bitcoin saw its biggest and most controversial change this summer, the evolution can all be traced back to one developer. Still, the founder of the controversial startup Blockstream and the network's most prodigious coder, Pieter Wuille, is a bit of a mystery. In an industry with no shortage of egos and bluster, though, Wuille is a rarity, choosing to let his code do the talking for him.

Erik Voorhees always seems slightly out of step. An early evangelist for the tech, Voorhees may be a rarity in that he has not only maintained but grown his relevance on the industry stage, all the while fighting for an unpopular block size increase and launching projects that seem years ahead of their time. Still, controversy seems not to catch this sly fox, as 2017 saw a victory lap for Voorhees, who emerged as one of the few early advocates who's been able to adapt to its changes.

In darkness or in light? Either way, Baldet seems right at home whether she's onstage at a banking conference or somewhere in the islands, posing for pictures at an "ethereum unicorn party." Will she emerge as a real deal innovator? Or is she the ultimate imposter banking infiltrator? While Baldet's story is yet to be told, her association with one of the largest banks in the world, and power position on its so far compelling blockchain efforts are more than enough to enthrall imaginations.

Master of the ASICBoost, conjurer of Antbleed... Perhaps no character in the pantheon of industry leaders has been the subject of more conspiracy theories than Mr. Wu, a passionate bitcoin believer who's been reviled for his views. The young co-founder of Chinese mining giant Bitmain, he might not exactly be the villain we all believe. But, what might be for certain is that if there's a title for "most misunderstood," Wu would win hands down.
