Why do "financial experts" hate Bitcoin? Why do people who have been in the financial industry for a long time seem to always talk negatively about it?  Does it threaten their livelihood or do they just not know enough and so they speak negatively about it?

I was looking at the quotes from financial experts about bitcoin and almost all of them were fairly negative, but also almost all of their titles were more traditional financial-type jobs:

I'm not sure why I understand all the hate from this group.
Financial experts do not hate Bitcoin. Some might hate Bitcoin -for several reasons including a conflict of interest as you suggested, but not all of them.

There are countless financial experts in the world including founders and investors in Bitcoin based businesses. Just do some more in depth research and you'll find them.

I looked at that page you provided the link to. My suggestions is don't take the Expert label for granted. Take a look at who these people actually are. Be vary of anyone who expresses a very strict opinion about something they don't necessarily understand.

I saw evidence of both non-expertise and outright ignorance on that page.
