Cryptocurrency dogecoin surges as Musk changes Twitter logo to 'meme dog'

A meme-inspired cryptocurrency's price jumped on Tuesday after Elon Musk changed the bluebird logo of Twitter to a dog associated with the digital token, despite the mogul being sued over his previous promotion of the coin.

Musk bought Twitter in October last year for $44 billion and has since slashed the workforce, introduced paid-for accounts and reinstated banned users including former president Donald Trump.

His decision to change the logo to a Shibu Inu dog, whether permanent or another short-lived joke, caused the price of dogecoin to surge by more than 20 per cent, from below $0.08 to more than $0.10.

The Twitter chief has 133 million followers and has long used the platform for self-promotion and humour, occasionally also promoting dogecoin, a highly volatile cryptocurrency initially created as a joke.

He is being sued for $258 billion by an investor who claims he lost massive amounts of money because of Musk's activities, though the billionaire has dismissed those claims.

The Shiba Inu dog became a popular meme in 2013 when posters on forums like Reddit and 4chan began using pictures of the Japanese dog breed alongside messages written in broken English.

The cryptocurrency was launched as a joke later that year and remained largely without value for years -- like thousands of other coins.

However, in May 2021 its value briefly spiked to a record $0.73 after Musk suggested his auto firm Tesla could begin to accept it as payment.
