update Bitcoin's blockchain technology and did not develop anything about it
There's no such thing as "Bitcoin's blockchain technology". Satoshi single-handedly created Bitcoin, and the protocol didn't change much from his original work, how can anyone be so ignorant of it?
maybe even now he is like other whales and is manipulating the market
This is nonsense, while no one can tell for sure exactly which coins belong to Satoshi, it is assumed that almost all of his coins weren't touched.
We can see that Nakatomo is useless now, he has no value.
If Satoshi returned today, he'd be very influential, especially if he decided to work on Bitcoin again.
