I do not expect a nobel prize-winning economist to say something like this. They will not know anything about bitcoin but prefer to start misinforming people and feeding them with wrong information.
People like this when you respect them better when you see them from afar. That way you'll continue to rate based on what they have done and the views you see than portray, but when you go deeper and see where they stand you might get disappointed.
We have a noble prize winner from my country too whom the whole country looked up to. Growing up he was used as the SI unit of intelligence (if you know what I mean). Fast forward to now, he's a strong supporter of our current government which is a disgrace. The government is so bad that whoever defends it sounds stupid and that's what this noble prize winner has turned to.
Another thing is these men are pretty old school and have refused to evolve. They believe in the traditional way of things. I read through the article and he makes sense to a certain degree and that's what I've come to conclude that it's just his opinion. I strongly always say that we shouldn't give people too much relevance in the Bitcoin space, not politicians like Trump. not Tech billionaires like Elon Musk, not Financial sector billions like Jamie Dimon, and certainly not noble prize winners like Paul Krugman.
Each of these people has their own opinions and their opinions are shaped by different things but its just their opinion, they're not bitcoin.
