So, are you sad that your latest attempt to save people from this great Ponzi

I do not remember when and where I said this.
These are your words, not mine.

What a big fat liar you are! Here is what you said...

Besides this, Satoshi seems to have had quite a few reasons to develop
Bitcoin such as fleeing from banks, creating a trustless system, etc.

OK. So my reason is to protect your life savings from this ponzi scheme called bitcoin

I want to prove that decentralized trustless system can not exists in long term.
It either transforms to centralized system or loses its security.

I think he was being sarcastic when he said that.

Sarcastic or not, there is no point in blatantly denying something that someone actually said.
