A transaction of 1432.92 btc happened today https://blockchair.com/bitcoin/address/1E6nViR5Xv1wyNXg87SamvtLJ5TyXuksLC .

The odd thing about this address is it ( almost ) contains block rewards from early days , specifically first reward is from block #2718 which is less than a month since launch . Only 2 transactions are not block rewards , a 0.01 btc and a 32.91 btc . All the other are coinbase rewards of 50 btc .

Did satoshi came back to spend his coins ? A very early miner or an early OTC buyer decided to take profits ?

Time will tell . I'll try to dig more to see if i can find anything . Any opinions or findings are appreciated .
