On August 3, it has been reported according to a series of tweets posted by Whale Alert that wallet addresses known to be associated with one of the largest breaches ever of a crypto exchange moved 620 Bitcoin (BTC) worth around $7 million over 4 transactions.

However, coupled with the recent movement of $39 million from July 27-28, this makes approximately $51 million in Bitcoin transferred over 17 transactions within a week.
It has been analyzed that on August 2, 2016, hackers breached security at Bitfinex by stealing 119,756 BTC, $72 million at the time. After four years and recent bullish behavior, their total haul is now worth $1.3 billion.
Within a week, criminals behind the Bitfinex hack moved more than 4,500 Bitcoin of the 120,000 tokens they stole in 2016 https://t.co/OJBR2eEo7t — Cointelegraph (@Cointelegraph) August 4, 2020
Despite the recent $51 million movement, those responsible for the hack have moved only 1-2% of the funds they stole.
Thus, this suggests that the criminals may be having difficulties as new anti-money laundering (AML) regulations are enforced.
