— In a 1,500-word memo obtained by The New York Times over the weekend, the company’s top lobbyist, Nick Clegg, sought to rebut Haugen’s allegations ahead of her unveiling in an episode of “60 Minutes” on Sunday night. “Social media has had a big impact on society in recent years, and Facebook is often a place where much of this debate plays out,” he said in the memo, in which he called Haugen’s impending accusations, which included blaming Facebook for January’s insurrection at the Capitol, “misleading.” He wrote that “what evidence there is simply does not support the idea that Facebook, or social media more generally, is the primary cause of polarization.”
Born in Latvia, Vavilov founded Bitfury in 2011 as a Bitcoin mining operation, but has expanded its business to include infrastructure projects such as data center operations, computer chips and software development for the crypto industry.

Bitcoin is widely regarded as the first modern cryptocurrency — the first publicly used means of exchange to combine decentralized control, user anonymity, record-keeping via a blockchain, and built-in scarcity.
And while proponents tout cryptocurrencies as potentially lucrative alternative investments, few serious financial professionals view most coins — with the important exception of Bitcoin and a few others — as suitable for anything other than pure speculation.
