I don't think that kind of news should be something surprising to you, unless you're new in the crypto space and don't know how things have been going for quite a while now, we have seen a lot of people and even men that matters in the world called Bitcoin a scam couple of time, this FUD caused a dip in the price of Bitcoin and we discovered that this same people who went about calling Bitcoin a fraud were the same set of people who took advantage of the dip in the market and made profit of millions of dollars in few hours.
Well, I love when FUD is being created, especially from a top person, that is the point I love entering the market most and buy more of the coin if it experience short dump, because like you said, these same people are still the ones that will eventually cause its pump too in future.
If anyone has enough patience, then these type of thing should always benefit such person, because no matter how dip the price goes, overtime, they gradually create FOMO after people must have forgotten the dip, and make the price of the coin shoot up again so they can sell off those coins they but from a panic seller.
