Some are even saying that it is Satoshi himself. After examining one of the addresses we can see that it was "allegedly" linked to an early bitcoin ponzi. See details below:
I don’t understand why every old wallet wake up is easily linked to Satoshi, people need to know that in 2011 or before 60,000 bitcoin were not that much and any one could have bought or mined it there, in this case it was reported that most of it were actually bought with $2 then. The amount seems huge now because of how impressive the bitcoin price has grown but in the past it was worth few bucks, didn’t we heard some paid 10,000 bitcoin in this period for just pizza.
For clarity it wasn’t only Satoshi that was involved in bitcoin then and for the fact that it has links to Ponzi schemes totally eliminates the possibility of it been Satoshi. Also it is not something surprising during periods like this move of large bitcoin like this usually happens either to take profit or to switch storage systems. Like in this case where there is no exchange it was linked to possibly this was a switch of storage
