Argentine authorities have ordered Tether to freeze 3.5 million USDT in funds associated with the multilevel scam Rainbowex, according to Bitcoin.com. The funds were frozen as part of an ongoing investigation into the alleged scam, which is said to have defrauded investors of millions of dollars. Rainbowex is accused of operating a Ponzi scheme, promising investors high returns on their investments, but failing to deliver. The freezing of the Tether funds is a significant development in the case, as it suggests that the authorities are taking the investigation seriously. It also shows that they are willing to use their powers to freeze assets that are suspected of being involved in criminal activity. The freezing of the Tether funds is a warning to other companies that are involved in similar activities that they could face similar consequences.
