How about Dr Doom aka Nouriel Roubini?
From
BBC NewsProf Roubini, who foresaw the financial crisis, says Bitcoin is "overhyped".
At a summit in Taiwan on Tuesday, he likened it to a "cesspool".
I love how they say he "foresaw the financial crisis." He has been predicting a financial crisis for decades, hence the moniker "Dr Doom". A stopped clock is right twice a day too. Just because eventually he is correct, doesn't mean he foresaw it. If a 20 year old predicts a financial crisis "this year" EVERY January 1st, eventually she'll be correct even though it had NOTHING to do with being prescient, just persistently wrong for many years before being right eventually.
