IMF managing director hristine Lagarde has called for a crackdown on crypto-currencies, saying the technology can be used to “fight fire with fire”.
She says governments around the world could harness the technology to stop illegal activity.
The anonymity of currencies such as Bitcoin means they are used by criminals and terrorists.
But the technology could be turned against such nefarious activities.
Regulators around the world have called for greater crypto-currency oversight.
It could just be an important turning point.
