“The Danish national bank has released a briefing note firmly declaring bitcoin to not be money, noting that the currency is more like ‘glass beads’. Denmark’s national bank is just the latest central bank to inveigh against bitcoin. In January, Malaysia’s central bank warned citizens that ‘the Bitcoin is not recognised as legal tender in Malaysia… the public is therefore advised to be cautious of the risks.’ In December 2013, the People’s Bank of China banned the country’s financial institutions from trading in the currency, shortly after the former president of the Dutch Central Bank said the currency’s boom was ‘worse than the tulip mania’.”
