Former bitcoin companies are erasing their embarassing 'bit's

As the cryptocurrency loses favour, it looks like some companies may be rewriting history to explain away their names

We've all been there: sometimes you start a company, run it successfully for a few years, and then realise you hitched your horse to a slowly dying technology and there's nothing you can do about it.

So spare a thought for the companies scrabbling to jump off the bitcoin ship before it sinks. The currency's value has been static for months (except for a brief boom and bust in early November when it was caught up in a Chinese ponzi scheme), but perhaps more damningly still, the hype has all but disappeared.
