Update: Turns out this address is the Coinbase deposit address… Is this 2015 ETH OG waking up after 6 months just to sell? If sold this time, they’ll profit $3.05M, with a 1,527.53x return, insane. BTW: The last time they made a big sale was 7 months ago, depositing 5,125 ETH ($9.64M) to Coinbase at an average price of $1,881.2.
