The electronic thief from the Bitfinex hack of four years ago continues to withdraw money, this time transferring the equivalent of $ 4.1 million in bitcoin to an unknown wallet address. Cryptocurrency tracker Whale Alert reported that hackers moved 416 bitcoin (BTC) on June 11. The funds, valued at $ 4.1 million at the time of the transaction, were deposited in 20 separate transactions, each worth from 15 to 33 BTC. This is probably the biggest pay day for hackers. When the stolen money first moved in June and August 2019, about 170 BTC and 300 BTC worth about $ 2.3 million and $ 2.7 million at the time, were flowing.
