If the opinion of Robert Schiller is seriously taken into account by investors from around the world, it is simply because he was the Nobel Prize in Economics in 2013. But when it comes to talking about Bitcoin, man does not chew his words. He is not seized by the craze that surrounds crypto-currencies for several months now.
Mr Schiller believes that Bitcoin is a speculative bubble that will end up exploding, even if in itself this virtual currency should not disappear.
One has always to contextualize situations, if you want to understand reality. In a way it is true that Bitcoin and cryptocurrencies are entering a bubble state. But it is even more true that mainstream finance is now in the state of a MUCH DEEPER BUBBLE, so Bitcoin & C. is still a safer haven compared with FIAT money these days.
For me no one can predict the price movement of Bitcoin, if there is someone who claims that he can predict Bitcoin then it is not right and the impossible. Note that the Bitcoin price movement is constantly changing at any time and that is a very common occurrence. Until whenever the government still has not made regulation around crypto then Bitcoin price will never stable. We just have to wait for the regulation issued by the government because with it Bitcoin can be much more organized in the financial system.
