Very suspicious transfers. I read the news that 400.000 BTC were transferred from old wallets in August!
There is nothing to be suspicious of, friends, for transactions that occur at that address. Each address owner has a private key, entitled to make transactions on his coin.joniboini and Z-tight have said that it is normal and from o_e_l_e_o response it can be a reinforcement that there is no need to be suspicious because at that time there were other miners who might be doing the activity and I don't agree if it was directed that it was satoshi who did it.
What I suspect maybe the OP meant to create this topic to tell everyone that this is one of the reasons behind the drop in the bitcoin price.
