I think its not a matter of hate, it's a matter of protecting their investments and I believe these are the guys that invest in the real gold bars as a way to store or measure their wealth.
Am certain if some one explained to them how exactly bitcoin works, they would be happy to jump on the bitcoin train without a doubt.
Millionaires certainly want to protect their wealth from being lost. Therefore he will reject something that he does not understand.
I also believe some millionaires hate Bitcoin, they just don't really understand how Bitcoin works. They must be frightened by negative
rumors about Bitcoin, then as we know most of the millionaires in the world are old people who find it difficult to accept new things.
So actually the main factor for people who hate Bitcoin, because they don't really know Bitcoin well.
For millionaires and even billionaires, they totally think bitcoin is a big scam because of the negative rumors that have spread around. They have all the wealth so they should know how to protect them as much as they want and avoiding bitcoin is one of it.
But i believe the main reason why they avoid bitcoin is they don't really know what bitcoin is all about so they don't feel interest investing on it. But for those who have become millionaires lately because of bitcoin, bitcoin is a big thing that would definitely change our way of living and even the standards on it.
