JP Morgan's chief executive Jamie Dimon spoke in an interview with Fox Business earlier today

Last year, he said that people who bought Bitcoin was stupid - saying that it was a fraud. Here was some of his comments at the time:

The currency isn't going to work. You can't have a business where people can invent a currency out of thin air and think that people who are buying it are really smart.

How quickly things have changed, really. It is reported in the interview he said that "blockchain is real" and that that initial coin offerings (ICOs) need to be reviewed individually.

But he still insists that he's not interested in the subject at all. Right, "not interested".
