Vencedor do prêmio Nobel de economia diz que moeda virtual Bitcoin é uma bolha
 
Jornal do Brasil
 
O vencedor do prêmio Nobel de economia, Paul Krugman afirmou que a moeda virtual Bitcoin é uma bolha. "É. Isso é mais óbvio até, penso eu, do que a bolha imobiliária, que eu já achava tremendamente óbvia", disse. 
O economista disse que o preço do Bitcoin é ajudado porque ninguém entende como funciona
Em entrevista à Business Insider, o economista disse que o preço do Bitcoin, que teve grande valorização nos últimos anos, é impulsionado porque ninguém entende como funciona, o que faz com que as pessoas acabem envolvidas pela mística de sua nova tecnologia.
 
"Tem essa mística sobre isso [Bitcoin], porque é algo tecnológico sofisticado e que ninguém realmente entende. Ainda não houve demonstração de que ele realmente seja útil na realização de transações econômicas. Não há âncora por seu valor. Ao contrário dos pedaços de papel com presidentes mortos, que estão ancorados pelo fato de que você pode usá-los para pagar impostos,  não há âncora para o uso do bitcoin", avalia.
 
PAUL KRUGMAN: Bitcoin is a more obvious bubble than housing was

Nobel de economia alerta: moeda virtual bitcoin é uma "óbvia" bolha
Nobel prize-winning economist Paul Krugman talks to Business Insider senior political editor Josh Barro about bitcoin. Krugman says the price of bitcoin is helped by the fact that no one understands it and people are caught up in the mystique of this new technology. Following is a transcript of the video. 
 
Josh Barro: Finally, I want to ask you about Bitcoin. Does the runup in bitcoin prices make any sense to you?
 
Paul Krugman: No.
 
Barro:  What's going on here?
 
Krugman: Bitcoin, nobody understands it. Which is for the time being a positive. It comes with this 
 
Barro: A positive for the prices?
 
Krugman: For the price of it. It's got this mystique about it, because it's some fancy technological thing that nobody really understands. There's been no demonstration yet that it actually is helpful in conducting economic transactions. There's no anchor for its value. You know, unlike pieces of paper with dead presidents on them, those are anchored by the fact that you can use them to pay taxes. There's not anchor for bitcoin. But bitcoin has developed this mystique. The price is going up, partly, it's tied up with Libertarian stuff ... I'm told that there are apocalyptic, the-end-is-coming guys who are accumulating bitcoin because once we turn into a Mad Max wasteland, having a digitally distributed – nevermind. So … I think it really doesn't make a whole lot of sense. And the psychology of it is clearly — if you're using the shoeshine boy test, my barber asked me about bitcoin. The feeling that people are caught up in something that they really don't understand, is overwhelming.
 
Barro: So you think this is an obvious bubble?
 
Krugman: It's the most — if this isn't … this is even more obvious, I think, than the housing bubble was. And that one was, I thought, tremendously obvious.
 
Barro: So sometimes a bubble can be obvious and yet can persist for a long time. And in fact you can – I mean, you know, I've been saying that Canadian housing is in a bubble for years, and it keeps going up. And so, I mean, the nice thing about calling a bubble is that you can always — if it doesn't burst, you can always say well it's just going to burst later. But I guess the question is how long can something like this go on with bitcoin?

Krugman: Well, the thing about bitcoin is there isn't actually a whole lot of stuff… there's not — in a way the fact that it's completely untethered to anything real means that it doesn't fall until it … it can just hang there in mid-air for a long, long time. There's no obvious real — it's not like, you know, the housing crisis. If housing prices are unrealistic, then more housing gets built and you can see it. Bitcoin — the cost of producing of new bitcoins has gone crazily high. So that's not going to happen. So we're waiting for a Wylie Coyote moment. You know, the cartoon physics, he runs off the edge of a cliff and it's only when he looks down and realizes there's nothing under him and he goes ... So we're waiting for that sort of thing to happen. And that can go on for a long time. You know, a bubble is a natural Ponzi scheme, that's how Bob Shiller puts it. That it's — as long as it's going on everybody who bought in keeps making money and it looks good, and the fact that in the end somebody's going to be left holding the bag. Everybody assumes it's not going to be them.
