Bitcoin smashed through another milestone over the weekend with a single unit of the digital currency breaching US$6,000 (S$8,168) for the first time, putting its gain this year to more than 500 per cent.
Bitcoin's epic run, which dwarfs the US Dow Jones stock index's own impressive run-up of 17 per cent this year, is defying repeated warnings from big banks and policymakers, who have called it a "fraud" and a "bubble". The cryptocurrencyhit a total market value of around US$100 billion, on a par with or above US blue-chip companies.
