Shiba coin is a joke that plays off of the popular Elon Musk-touted dogecoin, itself a parody that has gone mainstream in recent months. It’s just one of the many alternative cryptocurrencies that have popped up and exploded in popularity on the heels of bitcoin and ethereum.
Buterin, who was just 19 when he created ethereum in 2013, was a billionaire as of May 4 when the digital currency hit US$3500. Ether was on a tear, and hit a new record of $4385 earlier this week. One ether coin is now worth around US$3700.
