Bitfinex, one of the world's largest cryptocurrency exchanges, has sent over $120 million worth of USDT to an unknown wallet. The transaction was flagged by the blockchain tracking service Whale Alert, which reported that 121,071,544 USDT was moved from a Bitfinex address to an unknown wallet. The reason for the transfer is unclear, and Bitfinex has not yet commented on the transaction. However, the large size of the transfer has raised eyebrows, and some speculate that it could be related to the ongoing investigation into the exchange's alleged involvement in market manipulation. The transfer comes at a time when Bitfinex is facing increasing scrutiny from regulators. In April, the New York Attorney General's office opened an investigation into the exchange, and the Commodity Futures Trading Commission (CFTC) is also reportedly investigating Bitfinex. The investigation is focused on whether Bitfinex manipulated the price of Bitcoin in 2017. The exchange has denied any wrongdoing, but the investigations could lead to sanctions or even criminal charges.
