> He worked for various years as senior economist in a bank
Ah, it looks like you were in a coma between about 2006 and 2012. I have bad news. Sometimes (whisper it!) banks _employ incompetent people_. I would be reluctant to take "oh, well, he once worked for _HSBC_" as that much of an endorsement.
Not to say that everyone who worked for HSBC was incompetent. But, er, clearly they were not all hypercompetent either, given what happened.
He is experienced. I didn't say he did or didn't do a good job there. My answer is a response to "he has no experience as an economist". It's not a response to what you are argumenting.
You are systematically commenting trying to harm his reputation in issues not linked to his disreputable act of promotion of the shitcoin.
