Facebook is developing its own payment system based on cryptocurrency. The Wall Street Journal reported that the social network is bringing in finance firms and online merchants to support its efforts.

The effort, should it succeed, threatens to upend the traditional, lucrative plumbing of e-commerce and would likely be the most mainstream application yet of cryptocurrency. It comes as the social-media giant is under intense pressure from regulators, users and shareholders to address privacy shortcomings. At the heart of the initiative, under way for more than a year and code-named Project Libra, is a digital coin that its users could send to each other and use to make purchases both on Facebook and across the internet, according to people familiar with the matter.

Warren Buffett was pleased with Apple’s latest earnings report. He told CNBC that his company, Berkshire Hathaway, ‘haven’t changed our [Apple] holdings.” It holds around $50 billion worth of Apple stock.

“I was pleased with what they reported,” Buffett said, while noting he never makes investment decisions based on a single quarterly report. “What they talked about and reported is consistent with the reason we own $50 billion-plus of Apple.” Berkshire owned more than $40 billion worth of the tech giant as of end of last year, according to its 2018 annual letter. The conglomerate decreased its stake in Apple by nearly 3 million shares in the fourth quarter of 2018, but Buffett said at the time that the selling wasn’t under his direction.
