And Minds is already seeing solid movement. “In June 2018, Minds saw an enormous uptick in new Vietnamese of hundreds of thousands users as […]

What this signals is not that crypto is dead, however. It signals that the early, elated period of trading whose milestones including the launch of Coinbase and the growth of a vibrant (if often shady) professional ecosystem is over. Crypto still runs on hype. Gemini announcing a stablecoin, the […]
