Its obviously hacked account, Satoshi is long gone, And why will he/she even comeback now? Did he come back to solve this market manipulation? Someone is doing this to be able to gain attraction and fake news in my opinion.
There's a lot to be gained by claiming to be Satoshi. His influence over crypto development would be no joke to say the least.
The only reason he'd come back now is if he starts being interested in the project again, which I doubt given all the time that has passed. This is also why it's very unlikely he'd be driven by financial reasons. Also worth noting that he probably can't stop market manipulation from happening even if he wanted to lol.
