Nevertheless, the chances of bitcoin, the most popular of this new breed of self-clearing financial instruments, making it as a mainstream currency are now zero. Prices have been floundering at around $350 a coin for months, escalating losses for those who invested at last year’s $1,200 highs. Add to this a stream of high-profile scandals over the past year, such as the collapse of Tokyo-based currency exchange Mt Gox in February, and you realise it is not a question of if but when the public loses interest in this experiment entirely.
