First of all, it is hard to read a bulk of words like you've done. At least in the next thread you are doing, learn to make double spaces in every paragraph so we can see it very clean and very good to read.

Anyway regarding to your friend who was  a medicine expert turned into a scammer, I can't blame him TBH if he became a scammer. Take note that if there are no people who are ignorant, scammer will take advantage of it that is why knowledge is very powerful when it comes to investing. His friends trusted your friend and that "TRUST" is the reason why they are scammed by a huge amount.

Regarding to what he said, I don't care and most of us here doesn't care if that scammer hate Bitcoin. He idolizes Warren Buffet as I see with your post and we know already that Buffet is a huge cash holder waiting for any opportunities. Different people have different perspective with regards to Bitcoin. If he hates then so be it. He is not a lose to the community.
