We have to remember this is the same idiot that said this about bitcoin in October 2017:
"If you're stupid enough to buy it, you'll pay the price for it one day."
Like duh, you're always "paying the price" for it, its never free. On top of that, the timing of his comment was woeful.
This is also the same bozo that helped bring us the great recession and one of the bankers that absolutely should have been jailed for his role in furthering the collapse of the stock market. If I'm not mistaken he is stepping down from his position of CEO at Goldman Sachs by the end of this year. At least that's what he said he would do earlier in the year.
People care because the idiots that comprise Wall Street are glued to his every word as if he were Moses or something. Needless to say, if he mutters the words "buy bitcoin," a bunch of morons with money will start throwing it at bitcoin. That's why people care.
