Nobody seems to have a good answer to where Satoshi has gone and why he and his coins have not been seen for years.
I can think of only a few reasons why that might be.
1. He wants btc to succeed and knows spending his coins will cause a massive panic.
2. He is already rich and has no need for more money.
3. He was hired/tagged by an agency or institution and is under NDA.
4. He is sick of btc.
5. He hates attention/spotlight and does not want the leadership role.
What if the answer is even simpler? He had a car accident / heart failure and died. His wallets are lost and therefore never spent.
This is so much more reasonable and probable than "satoshi is an AI" or other crazy theories here. It's sad, but I think this might be the truth.
The chances that he is dead are rather high. He could have been the guy that had that terminal illness and got his body cryogenized, and he was the first miner and the person to recieve a transaction from satoshi himself, I forgot his name, how was it?
Even if he isnt that guy, im pretty sure he could have been another guy that is now dead. That, or he forget his keys, lost them, or he is a hardcore long term holder.
Btw, I just saw the news of Hal Finney bitcointalk account being accessed after years of innactivity (since he is dead) so probably he got hacked. Of course the satoshi rumors started again connecting that event with him:
