PANews reported on March 8 that according to Cointelegraph, a wallet associated with the darknet market Nucleus (holding over $400 million in Bitcoin) was activated after 9 years. On March 7, the entity controlling the wallet transferred $77.5 million worth of BTC to three new addresses, leaving only $365 million in the main wallet. The wallet has been idle since the market closed in April 2016, with 5,000 BTC being supplier and customer deposits.

Nucleus was one of a number of darknet markets that sprang up at the time, facilitating the sale of drugs, weapons, and other contraband. Although the official story about its closure was that it was hacked, conspiracy theories abound. Some believe that the Nucleus site administrator is running an exit scam, while others believe that the administrator has been arrested. Like many other darknet markets, transactions on Nucleus were primarily conducted in Bitcoin.
