JP Morgan, Goldman Sachs, and Warren Buffet the last few days (On Bitcoin)

For reference:

1. Warren Buffet is CEO of Berkshire Hathaway and Berkshire owns 2.5 billion shares of stock in Goldman Sachs.

2. Jamie Dimon is CEO of JP Morgan and said bitcoin was a fraud in October when Bitcoin daily volume was around 1 billion USD. Now Bitcoin volume is around 20 Billion USD per day. and he has since regretted calling it a fraud.

3. Goldman Sachs never talked bitcoin down but never said anything great about it until a few days ago so I give them the benefit of the doubt for attempting to understand this asset class
   by looking back at the only thing they know and that's Keynesian
   economics which bitcoin is decoupling since its a deflationary asset/currency.
