Re: Crypto currency is untracable right?
Nah, it's actually easier than that and I suspect the Feds have worked that one out too.
Most of the exchanges use the same remote library to generate the graphics they display (the whole thing is one money-grabbing exercise so there's no way they would allow you to run it locally because it would be cloned all over the world in seconds).
That library can't generate those graphics without the actual data, and as a US based company I suspect it's pretty much an open door for US law enforcement as crypto has become the currency to (attempt to) hide the proceeds of crime.
