Are there certain countries that practice cyberlaundering more than others?
Yes, however similar to the case of the legacy laundering, the money is typically made in the US and filtered out. The US will remain the largest conduit of illicit laundering due to the fact that theortically the largest laundering operations are concerned with the narcotics trade, and the US is the largest narcostics consuming nation on the planet. As well, it is land bound to the largest narcotics producing countries in the world, so the math is pretty solid.
