The world's most high-profile digital currency, bitcoin, hit a three-year high this week, rising above US$1,000 on Monday in a strong surge that saw it stand out as the best-performing currency of 2016.
Bitcoin, which shot up 125 percent in value last year alone, is now fast approaching its all-time high of $1,163 in late 2013, and stands at $1,027.53 at time of writing per price index CoinDesk.
While the extreme gains – which many expect to continue – make bitcoin look like an attractive bet, some investors are wary of the currency's history of extreme volatility.
