Argentina’s justice system has ordered Tether to freeze over $3.5 million in USDT linked to Rainbowex, a suspected pyramid scheme under investigation. The freeze follows a large-scale operation that involved 22 search warrants and the detention of 10 individuals. Rainbowex, which misled investors with promises of high rewards through crypto transactions, was found to operate in a closed-loop system, preventing withdrawals. The Argentine authorities received technical support from exchanges like Lemon and Chainalysis in their efforts. The investigation continues, with international warrants issued for two individuals involved.
