As far as I know the G20 meeting already took place and the verdict was that they can't regulate the crypto markets for now, but they will keep a close eye on them. In my opinion this news are only to scare people off and make them panic sell to drop the prices to a certain level so institutions and governments can buy at a lower price and get a second chance. This way they will gain more power in the crypto space and have a certain control over the prices and decisions made in the space. But hey, that's just my opinion.
