LONDON — Bitcoin's price stabilised on Wednesday after several days of volatility over the Christmas period, which saw it crash below $12,000 before recovering by more than $4,000 in short order. On Wednesday morning, bitcoin's price is little changed from its opening quote, trading at around $16,200 per coin, a gain of roughly 3%. One of bitcoin's biggest issues right now is that it is difficult to value with any objective criteria, and traditional investors remain very wary of it.
