We saw this for instance with the US elections where rumours are doing the rounds that massive amounts of money were channelled from foreign countries to influence the outcome of the election. This money had to be laundered through shell companies via Banks and complex money laundering systems.
All of this leaves paper trails and this can later be followed and investigated to find the true origin of this money.
Now think about this, why would "corrupt" governments want to appose Bitcoin and Crypto currencies, if they can use it to hide their "corrupt" practices? Would it not make sense just to allow it and then use it to further their political aspirations?
The push back from these corrupt governments does not make any sense. Could it be that they know that Bitcoin and Crypto currencies are not "anonymous" at all and that these transactions can be traced and for this reason they are apposed to it?
Curious to know what you are thinking.
