The recent transfer of 80,000 BTC, dormant for 14 years, came from wallets originally hosted by MyBitcoin. The wallets had been inactive since April 2011, before MyBitcoin collapsed in a hack that July. It likely belongs to the hacker or the anonymous founder known as Tom Williams. It seems Galaxy Digital bought the #Bitcoin from them, but I’m not sure if they did any forensics.

*Galaxy handled the 80K BTC sale for them.
