The block explorer [oxt.me](http://oxt.me) also shows the 2010 whale’s pattern of spending habits are always the same. One researcher discussing the subject with our newsdesk yesterday said: “Maybe they have some special application, a script, which is not really flexible and may get only 20 private keys at a time, but a list of receiving addresses.”

The whale has spent roughly 180 decade-old block rewards to-date, adding up to approximately 9,000 BTC. That’s over $400 million worth of bitcoin using exchange rates on Sunday, February 28, 2021.

Blockchair’s privacy-o-meter shows the mystery miner’s first spends are always susceptible to heuristics and transaction tracing tools.
