Bitcoin hiccoughed in Asian trading on Thursday to at one point stand more than 6% down on the day after failing to make record highs. Bitcoin, the world’s biggest and best-known crypto-currency, was last trading around $17,700, having lost more than $1,000 since its previous close. This year, bitcoin has risen 358.6% from the year’s low of $3,850 on March 13, but has not yet breached the $19,666 hit in December 2017.
