Just because of the crash bitcoin has been labeled a ponzi scheme? What government are you having?? Probably they are not doing their own researches on cryptocurrency. At the first place why is it just now? Bitcoin had ups and downs why didn't they banned bitcoin at the first place when it first drops from $30 to $2?
There are many news coming out of India regarding how the government is planning to look at the new market place, it is not because of the crash they are labeling it as ponzi and none of the officials said that about bitcoin, some illiterate members who does not have any knowledge about the market have said those things about bitcoin and the central bank has banned the banking sector from dealing with businesses related to crypto and that is the real situation in India from what i understand, after the G20 summit there are news coming out that they will be coming up with regulation .
