According to Twitter's cryptocurrency industry video v, Chris Dunn, an incubator partner, said on Twitter that most of its cryptocurrency videos posted on YouTube were forcibly deleted by Youtube. According to Chris, YouTube ’s official reasons for the removal were “the video contained dangerous or harmful content” and “the sale of allegedly regulated goods”. The screenshot given by Chris shows that the deleted video content includes Bitcoin investment, token financing, how to trade cryptocurrencies and so on. It is currently uncertain whether YouTube has a new policy on cryptocurrency regulation. In response to Chris's tweets on YouTube, YouTube has not yet responded.
