At the Bitcoin 2021 Conference on Friday, Jack Dorsey, co-founder of Twitter and Square, spread further positivity about the cryptocurrency, CNBC reported.

"Bitcoin changes absolutely everything," Dorsey said. "I don't think there is anything more important in my lifetime to work on."

He continued: "If I were not at Square or Twitter, I would be working on bitcoin. If [bitcoin] needed more help than Square or Twitter, I would leave them for bitcoin."

According to Dorsey, bitcoin is capable of creating a new financial system that is more inclusive and supportive for neglected communities, per CNBC.

He also sees cryptocurrency as a way to protect against currency depreciation and quicken international transactions for people all over the world.

This is why Dorsey and Jay-Z partnered on a new bitcoin endowment in February, which will be focused on developing the cryptocurrency in India and Africa.

Called "₿trust," the endowment was funded with an initial investment of 500 bitcoin, worth roughly $23.6 million.

"I don't think there is anything more enabling for people around the world," Dorsey said.

Dorsey has always been a staunch supporter of bitcoin among a sea of critics, some of whom have described the cryptocurrency as "disgusting" and worthless.

Insider reported in May that the tech mogul believes bitcoin changes everything for the better and that he would work "forever" to improve the cryptocurrency. He followed up by saying that "no single person (or institution) will be able to change [the cryptocurrency], or stop it."

Back in March, Dorsey sold his first tweet as an NFT, converted the proceeds of the sale into bitcoin, and then donated it to Give Directly's Africa Response.
