I don't know how true this news is but obviously this is going to come one day, governments want some excuse or the other to close Cryptos, they know to maintain financial autonomy with them they need to keep a check on completely decentralised Cryptos and there is nothing more decentralised as bitcoin if they would ban it eventually the rest of the market is won't be able to flourish back for a long time too. Otherwise we all know the net carbon footprint of bitcoins isn't much different than that of the fiat and banking system.
