New South Wales police have charged a 42-year-old Sydney man for an alleged $3.5 million cryptocurrency investment scam targeting over 190 elderly Australians. The scam involved fraudulent investment pitches via social media and fund transfers through an online portal called 'NEXOpayment,' with authorities uncovering money laundering patterns. This case is part of a broader crackdown on crypto-related crimes in Australia amid increasing sophistication and victimization in such frauds globally.
