Cryptocurrency Blockchain tracking Twitter account Whale Alert stated on Monday that the Bitfinex hacker is moving around millions of dollars worth of Bitcoin stolen during the enormous Bitfinex exchange security breach in 2016 to unknown wallet addresses.
Significantly, Whale Alert has documented a total of nine transactions on Monday that illustrated the movement of around 2,550 total Bitcoin ($27 million) move from wallets linked with the 2016 security breach into new unknown wallet addresses.
In 2016, Bitfinex was a victim of a substantial security breach that lead to hackers stealing 119,756 BTC from the cryptocurrency exchange. This is not the first time that the Bitfinex hacker has moved the stolen Bitcoin to unknown wallets.
It represents one of the most devastating BTC hacks in history and easily one of the single-biggest by coin count. However, it is not comparable to the notorious Mt. Gox hack that occurred in 2014 where hackers managed to steal 850,000 BTC from the Mt. Gox exchange. The coins were worth more than $450 million at the time of the security breach and $9.5 billion today.
