Casa CTO Jameson Lopp has noticed a tidbit in the most recent CoinMetrics report. It appears that the sixth richest Bitcoin address holds 79,956 BTC (approximately $650 mln at today's prices) that was stolen from the now-defunct Mt. Gox exchange.
Ill-gotten coins
Notably, these coins have been touched since 2011 (the year they were stolen). It was either a very disciplined holder or someone who lost access to their private keys. CoinMetrics states that the latter is the most likely reason behind this eight-year silence.
One of the biggest security breaches in the history of crypto occurred on June 19, 2011. The hacker was able to artificially tank the Bitcoin price to just $0.01 by creating a mammoth-size ask order.
Mysterious whales
It might be one of the richest addresses considering that the fattest Bitcoin wallets actually belong to cryptocurrency exchanges that use them as a cold storage.
As reported by U.Today, there are plenty of the so-called "zombie addresses," which haven't seen a single transaction in more than 18 months.
One enormous Bitcoin wallet is believed to be in the hands of an anonymous Asian billionaire.
