Internal revenue services (regardless of the country) trying to take people's money is not a new thing, not even in cryptocurrency world. They have always been pushing for more surveillance and control so that they could always
keep their hands in everyone's pockets.
Panic selling bitcoin, which is the only currency in the world that nobody can ever control, shows how little people understand it. Not to mention their increased trading volume subjects them to more taxation
Anyways, this is just the brand new type of FUD that will replace the "China banned FUD" for at least 2 or 3 years.
