Odaily Planet Daily News: New York Attorney General Letitia James sued two companies and their promoters, accusing them of running a cryptocurrency pyramid scheme that defrauded investors of more than $1 billion. The first case involved a cryptocurrency mining investment program, AWS Mining, which promised investors a 200% return, but the company went bankrupt in April 2019. Another company, NovaTech, claims to be a cryptocurrency and foreign exchange trading platform. Documents show that from August 2019 to April 2023, investors deposited more than $1 billion worth of cryptocurrency in NovaTech, but the actual transaction volume on the platform was only $26 million.
