On December 2nd, the new express article "Resurgence of" Cryptocurrency "under the coat of" blockchain "resurrected." The article pointed out that Aircoin and copycat exchanges are making a comeback. The promotional methods of these "air coins" are similar, they are mainly high-yield, and the model is still the old-fashioned MLM style. In response to the resurgence of virtual currency hype, regulators in Beijing, Shanghai, Shenzhen and other places have "bright swords" to investigate the activities related to virtual currency transactions. Compared with the previous round of clearance, the nationwide clean-up and rectification intervention was earlier, and many local regulators said that they would crack down and clean up from an early age.
