Thousands of people have descended on Miami for a massive two-day bitcoin conference that opened Friday — a sign that the US city, in the midst of a tech boom, is hoping to become the next cryptocurrency hub. “I don’t think there’s anything more important in my lifetime to work on” than bitcoin, given the flexibility it offers, billionaire entrepreneur Jack Dorsey, the co-founder of Twitter and payments firm Square, told a crowded auditorium. “We don’t need the financial institutions that we have today. We have one that is thriving, that is sound, that is owned by the community, that is driven by the community,” said Dorsey, one of the keynote speakers at Bitcoin 2021. Dorsey tweeted Friday that Square was considering making a hardware wallet for safely storing bitcoin. With 12,000 participants and all speaker sessions sold out, the Bitcoin 2021 trade show features exhibits from crypto mining companies, crypto traders and bitcoin exchange networks. The conference was originally scheduled to take place in Los Angeles, but was moved due to tougher coronavirus restrictions in California. The line to get into the Mana Convention Center in Miami’s trendy Wynwood neighborhood wrapped around the building. Everyone was in high spirits and there were no face masks to be seen. Beyond Dorsey, two of the other speakers were Cameron and Tyler Winklevoss, twin Harvard classmates of Mark Zuckerberg who sued him over claims he stole the idea for Facebook from them, and now run cryptocurrency exchange Gemini. “We think bitcoin is gold 2.0,” Tyler said at a panel discussion. “When we get to Mars, what is the currency going to be in Mars? Dollars? No. Bitcoin.” ‘A movement’ So where does Miami fit into the picture? For David Abner, Gemini’s global head of business development, Miami is “centrally located, especially in the Americas, and there’s a lot of political support here.” “I think they’ve spent time to understand it and think about the ramifications of bitcoin. And so they’re very supportive of the economy,” Abner told AFP, adding that cryptocurrency could revolutionize remittances sent back to Latin America. Miami Mayor Francis Suarez, who opened Bitcoin 2021, has become a bit of a celebrity in tech circles, for his intense efforts to turn the Magic City into a beachfront Silicon Valley.
