I read this on Bitcoin News , additional information in cryptoworld.
Cybersecurity experts have warned that half of the stolen "NEM" coins might have been laundered already on the darknet.
That's why Japanese authorities have decided to set up a center dedicated to combatting cybercrime, including crypto theft . 500 analysts and investigators from different branches of country's law enforcement agencies have joined the unit.
I know some members here have their NEM token on their wallet...
This restriction of Japan on the growing cybercrime trend in crypto world is what we need to avoid different scams.
Nem hack happened ages ago.
Security for cryptos are especially important because of the fact that they are irreversible. Since it is decentralized, there is no way for a central entity to reverse payments the same way it is done through the banking system. So exchanges should always protect their wallets with sufficient measures, something that wasn't done in the NEM hack.
Scams are a completely different thing. Crypto scams can happen to anyone that is buying stuff with BTC. Again, the irreversibility of btc is exploited.
