Jack Dorsey and Vitalik Buterin have been squabbling for months over whether bitcoin or ethereum is better. Here’s how their head-butting began.

And it’s bitcoin or nothing for Dorsey

In June 2021, Dorsey told Miami’s bitcoin-loving conference crowd that he’s all in on the coin and dismissed the likes of ethereum and dogecoin, the latter being an Elon Musk favorite.

“All of the other coins, for me, don’t factor in at all,” Dorsey said, later adding that bitcoin will be the most important work that he does during his lifetime and that he will never buy ethereum.

He has called bitcoin’s 2008 white paper “poetry.”

Simply put, he thinks bitcoin will be the future native currency of the online world, even tweeting “Yes, Bitcoin will” in response to rapper Cardi B’s tweet asking if crypto is going to replace the dollar.

Dorsey did not immediately respond to Insider’s request for comment ahead of publication.

It’s worth noting he did tweet in 2021 in response to a user asking about his ethereum “hate” that “focus on one thing isn’t hate of the others. I’ve made my concerns known about others in comparison to Bitcoin. Key ones are founding principles, security, and centralization.” 

However, he would still later make public remarks against the Ethereum technology.
