You are playing into the soundbites of the entrenched and afraid. If you look at facts, you see you fell into propaganda.
"A recent report tracking the circulation of funds within the bitcoin economy from 2013 to 2016 concluded that less than 1% of bitcoin transactions stemmed from coins of illicit origin. In comparison, it is estimated that between 2% and 5% of global GDP or $800 billion to $2 trillion in U.S. dollars is laundered annually. Not only is cryptocurrency harder to launder at scale, but its prevalence is significantly lower than fiat currency. Just dont expect your government to tell you that."
