In Luxembourg, a big conference just wrapped up with experts from 90 countries. The hot topic? How scams and money laundering are increasingly using cryptocurrency. The old methods of tracking through banks aren't cutting it anymore.

Police and financial departments are now turning to blockchain analysis tools to track suspicious wallets and money flows. They're trying to freeze and seize funds before they get transferred or exchanged.

Cryptocurrency moves fast and easily across borders, so international police and financial intelligence units need to step up their collaboration. At the conference, they emphasized not just catching the criminals but also quickly tracing and freezing assets to recover the proceeds of crime.
