Hong Kong authorities have cracked a 360 million Hong Kong dollar ($46.30 million) scam involving cryptocurrencies and arrested 27 suspects. Hong Kong police launched a special operation code-named "Secret Words" earlier this month and arrested 27 suspects suspected of plotting an online love scam over a period of about a year and luring victims to invest in cryptocurrencies, eventually defrauding them of their money, local news outlet HK01 reported on Tuesday.
