CEO Elon Musk has been actively tweeting about digital currencies in recent weeks, driving his followers to buy them. Because of this, the billionaire has been attributed for the price spike of alt coins like BTC and Dogecoin. Tesla also announced, it would start accepting BTC as a payment method for its products. In a filing with the U.S. Securities and Exchange Commission (SEC), the automaker clarifies that the move will be \u201csubject to applicable laws and initially on a limited basis\u201d. While many digital currency enthusiasts welcome the news, others have expressed apprehension.\u00a0Gary Black, a Tesla shareholder, private investor and former Goldman Sachs executive said he is unloading his shares citing investing in BTC is risky. He tells his over 50-thousand Twitter followers that Musk\u2019s action is \u201chubris.\u201d https:\/\/twitter.com\/garyblack00\/status\/1359304624113606656?s20 CoinGeek historian Kurt Wuckert Jr. also weighs in on the issue. He says,\u00a0\u201cElon has BTC. And if he wants he can spend it one day just as long as the rest of the planet isn\u2019t also trying to broadcast more than 6 megabytes per hour at the same time. Then he can\u2019t spend it, because that\u2019s just how BTC works now.\u201d Meanwhile in Asia, China\u2019s Beijing has intensified its digital currency trial by handing out online \u201cred packets\u201d worth a whopping 10 million yuan.\u00a0That\u2019s equivalent to US$1.5 million. Some 50,000 locals received 200 yuan in digital red packets this week via lottery. The move aims to\u00a0increase local consumption and encourage migrant workers to stay in the city for the Lunar New Year festivities. It is also a part of a wider test that will eventually see digital yuan being used in the 2022 Beijing Winter Olympics.\u00a0 Now, here\u2019s a story of two companies showing how blockchain technology can be used to help our planet. Gillette partners with blockchain-powered recycling firm Plastic Bank to use digital tokens to incentivize plastic collection and track the recycling through blockchain. In a report by\u00a0McKinsey & Company, sourcing sustainable materials is becoming a top priority for lifestyle and fashion companies. That\u2019s why TextileGenesis, a company based in Hong Kong and India\u00a0is also using blockchain technology to create a permanent record of every stage of its clothing production. The result, fashion brands are now more transparent by tracking the production from raw materials to the finished product. Blockchain technology is earning the trust of many companies because of its stable and secure system as a public ledger of truth. TextileGenesis was awarded in the past for innovations promoting a greener fashion industry and running a pilot project with global fashion brand\u00a0H&M.
