Now that the person with 80,000 BTC appears to have sent some of the funds to Galaxy, perhaps to sell, it is worth pointing out that this could mean the "Salomon Brothers" OP_Return messages are a coincidence and nothing to do with the funds being spent Old addresses with large balances have received stupid incoming spam messages for years. Some examples related to this 80,000 BTC include: * March 2019: OP_Return message "We'll buy your Bitcoins. http://sell.buy.bitcoin@protonmail.com" * March 2020: OP_Return message "http://WWW.BTCKEY.CO Buy your empty private key" Plus the address receives insciptions, dust from deceptively similar addresses and all other kinds of crap
