<https://www.theguardian.com/business/2018/feb/27/hawk-or-dove-bitcoin-is-for...> A few days ago, President Nicolás Maduro of Venezuela announced that his government had launched the petro, a new state-sponsored cryptocurrency. He claimed that $735m (£529m) worth of the new currency had already been sold, though observers are sceptical, unless state entities have been obliged to buy them. Even they will find it hard to do so, however, as the technology platform on which the petro will be traded has not yet been confirmed. Venezuela's new bitcoin: an ingenious plan or worthless cryptocurrency? Read more International demand for the petro will not be helped by recent pronouncements from Warren Buffett and Charlie Munger, the “sages of Omaha” who still control Berkshire Hathaway. Speaking of cryptocurrencies in general, Buffett was scathing. “I can say almost with certainty that they will come to a bad end,” he declared in January, while noting for good measure that he would be glad to buy put options on every one of them. Munger is, if anything, even more hostile, characterising bitcoin in particular as “totally asinine” and a “noxious poison”. Not much room for doubt there.
