On November 25th, Bitcoin research firm BTCparser said in an article published recently that a large number of Bitcoin wallet addresses were created in 2010, each holding 50 bitcoins, and these addresses were not transferred until the first "activation" in November 2019. The article calls it the "2010 Whale". His theory suggests that Mr. Nakamoto owns the wallets and has been slowly selling off his holdings, while deliberately ignoring the 2009 wallets to avoid attracting attention, "leading me to suspect that the mysterious 2010 whale might actually be Satoshi Nakamoto." But BTCparser stresses that this is just a "theory, not a conclusion."
