• Bitcoin Price: $388.76 (£247.90, €312.61, via CoinDesk.com)

Bitcoin has continued its resurgence with a further 5% increase in value since yesterday to take its price back up towards $400.

Litecoin, dogecoin, peercoin, darkcoin and namecoin have seen more modest gains of between 1% and 4% over the last 24 hours.

The biggest mover across all markets was guarany. The "original brazilian cryptocurrency" surged by 65% to take its market capitalisation above $80,000.

Bill Nye's Bitcoin watch

Just a few weeks after Bill Nye 'The Science Guy' said that he wanted to have bitcoin in his analog watch, a cryptocurrency enthusiast has adapted a watch to do just that.

The Seiko watch was modified with a near-field communications (NFC) chip that can be scanned with a phone in order to facilitate bitcoin transactions between wallets.

"A few weeks ago Bill Nye said he wanted bitcoin in his analog watch and that's exactly what I did," Reddit user Essofluffy said. "The NFC tag contains an address for the private key within. It can be scanned by any phone with an NFC reader."

Western Union vs. bitcoin community

Western Union has been attempting to quash a parody advert that depicts bitcoin as a superior money transfer method.

One Facebook user had the advert removed by moderators on the social media platform as a result of copyright infringement claims.

However such actions have been dismissed widely, with a consensus amongst the cryptocurrency community that the advert fits into the category of parody and therefore any copyright claims are unfounded.
