Electric car maker Tesla will stop accepting Bitcoin as a payment, CEO Elon Musk tweeted on Wednesday, citing environmental concerns.


"We are concerned about rapid increasing use of fossil fuels f...or Bitcoin mining and transactions, especially coal, which has the worst emissions of any fuel," Musk said on Twitter. He added that cryptocurrency is a "good idea on many levels" but its promise cannot come at a "great cost to the environment."

Tesla, he added, won't be selling any of the Bitcoin it owns.

The price of Bitcoin fell about 5% to $51,847 after Musk's comments on Twitter. Tesla's stock finished Wednesday down 4.4%.

Tesla said in February that it had invested around $1.5 billion in Bitcoin and it planned to begin accepting the digital currency as payment "soon." The fair market value of Tesla's Bitcoin holdings as of March 31 was $2.48 billion, according to securities filings.

Bitcoin relies on computers, which rely on electricity, to exist. The number of computers and the energy needed to power them is rising — the growing value of Bitcoin is directly tied to the amount of energy it uses.

Bitcoin miners unlock Bitcoins by solving complex, unique puzzles. As the value of Bitcoin goes up, the puzzles become increasingly more difficult, and it requires more computer power to solve them. Estimates on how much energy Bitcoin uses vary.

A 2019 study by researchers at the Technical University of Munich and the Massachusetts Institute of Technology concluded that, in late 2018, the entire Bitcoin network was responsible for up to 22.9 million tons of CO2 per year — similar to a large Western city or an entire developing country like Sri Lanka. Total global emissions of the greenhouse gas from the burning of fossil fuels were about 37 billion tons last year.

EBay Inc (EBAY.O) is open to the possibility of accepting cryptocurrency as a form of payment in the future and is looking at ways to get non-fungible tokens (NFTs) on its platform, the company said on Monday. ...

A growing number of companies have begun to accept virtual currencies as a form of payment, taking an asset class that had been shunned by major financial institutions a few years ago, a step closer to becoming mainstream.

Tesla Inc (TSLA.O) is already accepting bitcoin as payment for its electric cars, while payments giant PayPal (PYPL.O) last year started allowing customers to buy, sell and hold cryptocurrencies using its online wallets. read more

"We are always looking at the most relevant forms of payment and will continue to assess that going forward. We have no immediate plans, but it (cryptocurrency) is something we are keeping an eye on," eBay said in a statement to Reuters.

In an interview with CNBC, Chief Executive Officer Jamie Iannone said that accepting virtual currency was an option the company was looking at.

EBay, which disappointed investors with a weak second-quarter profit forecast last week, said it was looking at a "number of ways" to get into the NFT space. read more

NFTs, a type of digital asset that exists on a blockchain, have exploded in popularity this year, with NFT artworks selling for millions of dollars and musicians such as the Kings of Leon rock group embracing them for their latest album. read more

"We're exploring opportunities on how we can enable it (NFTs) on eBay in an easy way," Iannone said on CNBC.

I considered a lot of very dorky, honestly unsophisticated puns to sprinkle in this post's wordsmith labyrinth. Instead, I'm going for a more classic look. Why is it that I don't understand!? But, every now and... then, a crypto super hero only wants to hide and enjoy a sideways market. Sunday, to be precise... Palm Sunday.
I'll start with the less difficult of the two: Saylor, Michael. We'll probably do a deep dive on Saylor at some point in the future, but for now, you know the drill.
Michael Saylor has been a vocal advocate for a strong corporate strategy to convert revenues, investing, lending, sales, and a number of other organizational strategies to Bitcoin. Bitcoin, in his opinion, will continue to grow in value forever, while fiat currency will continue to fall in value indefinitely. Following the principles of conventional finance, the inflationary laws of financial physics, and seeing the horrific experience of bursting deficits is not a novel concept. It's clever. Putting this much confidence in crypto may be one of the most daring tactics, but it's that kind of daring that gets us talking, right?
I've spent a lot of time listening to Saylor break down details he's presented at business conferences, sharing various tactics others have used and how they're incorporating Bitcoin into their corporate structure. There's no way he understands what he's talking about. It's interesting to hear someone who is well-versed in finance clarify the facts of our current economic condition to the rest of the conventional financial markets, and that they are paying attention. Fortunately for us, the financial district is already lagging behind government policy (I hear a distant Amen from a thousand crypto projects struggling to get their clarity)
As he led the conference for corporate strategies in Bitcoin, I made a joke that Microstrategy's'strategy' was actually a macro strategy, but after getting to know his work a little better, it appears they already picked up on the pun; nothing clever or original going on here! lmao

The more Saylor talks, the more optimistic the reasoning behind big corporate capital pouring into cryptocurrency becomes. We've seen reports of significant amounts of Bitcoin leaving Coinbase and other exchanges, and we think these are indicators of the HODL at the top of the food chain. Bullish, to say the least.

If you read my article about ETFs, you might be wondering what effect this news will have on markets and the price of Bitcoin, especially because people can basically gamble on the price of Bitcoin without actually dealing with it. However, I am convinced that the loudest voices who make the most sense will inspire the most people, and businesses, to grab the real deal. Due to its scarcity model, this will certainly weigh heavily against the price of Bitcoin (unless governments blow it up, of course). I don't think we'll ever come to a point where the SAT is no longer useful. People who own a few SATs at a time

Tesla CEO Elon Musk announced late Tuesday that it is now possible to buy Tesla vehicles in the U.S. with bitcoin.

The automaker last month revealed that it had bought $1.5 billion worth of bitcoin and... that it would soon start accepting the world’s most popular cryptocurrency as a form of payment.

“You can now buy a Tesla with Bitcoin,” tweeted Musk, who was officially made the “Technoking of Tesla” this month.

A support page on Tesla’s website explains how customers can pay for a Tesla using digital currency. The company’s electric vehicles typically cost between $37,990 and $124,000 before tax.

People outside the U.S. will be able to buy a Tesla with bitcoin “later this year,” Musk said, without specifying which countries.

In order to accept the payment, Musk said Tesla is using “internal” and “open-source software.”

He added that Tesla “operates bitcoin nodes directly.” Nodes are computers on bitcoin’s network that work to verify transactions and avoid the cryptocurrency from being spent twice.

Elon Musk, who caused the increase in the value of Bitcoin and Dogecoin with his previous statements, caused another crypto currency to double in value with his latest share. However, the increase this time was... due to a misunderstanding as in Musk's earlier "Use Signal" tweet.

The crypto money market continues to be shaped by the influence of Elon Musk's posts on Twitter.

A post made by Musk, who is the second richest person of our planet, on Twitter caused the value of the crypto money named "MarsCoin" to increase in a short time.

Responding to the share made by Changpeng Zhao, the CEO of the crypto money exchange Binance, to issue his own crypto currency, Musk said, "It will definitely be a MarsCoin."

This response of Musk soon led to the rise of a cryptocurrency, already named MarsCoin.


The "Use Signal" tweet that Musk posted to criticize WhatsApp in the past period also caused the wrong Signal share to rise.

Vole ga i najbogatiji čovjek svijeta, ali i ljudi s par tisuća viška. Stručnjak objašnjava zašto i što slijedi

Dok entuzijasti u kriptovalute masovno ulažu u bitcoin čija vrijednost strmoglavo raste, e...konomski analitičar Davor Gatara pita se što će investitori učiniti kad ga više ne bude bilo moguće ‘izrudariti’

Dok se gospodarstva diljem svijeta oporavljaju od ekonomskih posljedica lockdowna koji su izazvali koronakrizu, burze su u drugoj polovici prošle godine počele aktivnije trgovati. Nagovještaj je to oporavka kojeg su prognozirali Međunarodni monetarni fond, Svjetska banka i Europska komisija. No, kratku, ali duboku krizu gotovo da nisu niti osjetile kriptovalute. Ona najjača, bitcoin, postala je još jača, pa je proteklog utorka po prvi puta njegova vrijednost prekoračila magičnu granicu od 50.000 dolara. Tako je vrijednost jednog bitcoina u trenutku pisanja teksta bila oko 55.286 dolara ili 345.401 kuna i neprekidno je oscilirala.

Za to bi se moglo kriviti kretanja na paralelnom, digitalnom financijskom tržištu, no vrijednost bitcoina je skočila za 14 posto kada je južnoafrički multimilijarder i trenutno najbogatiji čovjek na svijetu, Elon Musk najavio da će Tesla uložiti milijardu i pol dolara u bitcoine te da će se njima moći kupovati njegova električna vozila. Od početka godine, vrijednost bitcoina porasla je za ukupno 72 posto, pa su tu u igri svakako i brojni drugi faktori.

Jedan od njih je i to, što ga je, prema riječima ekonomskog analitičara Marija Gatare, nemoguće svrstati niti u jednu klasičnu kategoriju financijskog dobra. Usprkos tome, usporedio ga je s jednim od najcjenjenijih dobara, po čijoj se vrijednosti burze i dalje ravnaju.

“Ključna je stvar da je bitcoin teško klasificirati ili kategorizirati. On nije imovina, jer ne donosi nekakav prinos. Nije ni valuta u ovom trenutku, jer nije općeprihvaćeno sredstvo plaćanja, zato što toliko divlja i ima ogromne oscilacije. Ekonomisti se još uvijek spore oko toga što je zapravo bitcoin. Vjerojatno je najbliži zlatu i sličnim kategorijama”, pojasnio je Gatara za Net.hr te dodao da ne može objasniti varijacije u vrijednosti bitcoina, istaknuvši kako se vjerojatno radi o euforiji u kojoj se ljudi nadaju kako će njegova vrijednost biti još veća.

Blockchain technology that originated from a mathematics branch called cryptography can seem difficult, and it can certainly be for any ordinary individual, but its central idea is pretty basic indeed. The tech...nology first gained recognition as a cryptocurrency network such as Bitcoin. Traditional tracking systems are unable to scale with increasing demand for fast distribution services, so the blockchain future is close and is now expanding through a wave of industries.

To make faster paced decisions, companies need modified, secure and authentic data nowadays. In any sized company, it plays a larger role as it offers a scalable, immediate solution for every order authentication. Blockchain technology is basically a virtual ledger capable of tracking and verifying a high volume of digital transactions, allowing business processes to be more productive and cost-effective. New platforms created by Blockchain allow simple document coordination on a shared distributed ledger, making physical paperwork largely unnecessary.

Approvals and customs clearance can become faster with the use of smart contracts, reducing processing times for goods at customs checkpoints, which means entrepreneurs can run their companies more transparently. As the whole network leads to data authentication, Blockchain ensures trustworthy data across the transport and logistics ecosystem. For improved supply chain management, more open contracts, quicker payments and faster background checks, Blockchain can be a game-changer. Using the Internet of Things (IoT) and AI (Artificial Intelligence), Blockchain allows better freight tracking to improve performance, which can be especially useful for capacity monitoring. It also conducts efficient fleet or vehicle performance history monitoring for simpler & accurate on boarding of the carrier.

Intelligent contracts with efficient cost control and removal of intermediaries improve liquidity in the supply chain. Blockchain can evolve over time and, because of their distributed existence, are theoretically self-sustaining. Organizations across the business spectrum are coming to the realization that they can use blockchain technology to streamline their activities and provide their customers with better services. Together with intelligent contracts and digital currencies, the blockchain can make trade and government processes safer, quicker, more efficient and more scalable. And as more and more small players, backed by digital technology, enter the market, the economy will continue its journey towards decentralization.

Several developments in the last 48 hours signal the increasing acceptance of cryptocurrency into mainstream culture and finance. As Coinbase prepares to go publ...ic traders are exchanging shares on the NASDAQ Private Market. These trades point to a total value of about $77B for Coinbase, which is the largest U.S. based crypto exchange.

Meanwhile Jeffrey Gundlach, founder of the investment firm Doubleline Capital LP and known gold bull, implied in a Wednesday tweet that Bitcoin might currently be a better trade than gold.

https://twitter.com/TruthGundlach/status/1362257187771277315

The billionaire ‘bond king’ has turned bullish on BTC after previously being more neutral, according to Bloomberg.

In Canada North America’s first Bitcoin exchange-traded fund debuted on the Toronto Stock Exchange today. The Purpose Bitcoin ETF (BTCC) reported heavy trading compared to typical first day EFTs with $80M worth of shares changing hands in the first hour alone.

Slow Ventures principal @jillruthcarlson says blockchains can democratize finance — if people run their own nodes.

Have you ever tried to sync a Bitcoin node or another blockchain node, essentially dow...nloading the entire history of the network to your computer? Not with your super-high-speed internet, but out in the wild, where most people live?

Jill Carlson, a VC and advisor to blockchain projects such as Algorand and Tezos, has—and she doesn’t think it’s a great advertisement for blockchain technology.

“I once had the experience, the joy of syncing a full Monero node from my parents’ condo, where the internet was really spotty and it took, like, two weeks to do, and they were all, like, ‘Isn’t this supposed to be the future of finance?” Carlson, who this week joined the Mina Foundation board, told host Matthew Aaron of The Decrypt Daily podcast.

In Carlson’s view, if you’re not syncing a node, you’re not fully participating in the future of finance. It’s the main reason why she’s excited to be a part of Mina, which has attracted investments from Coinbase co-founder Fred Ehrsam and crypto angel investor Naval Ravikant.

Mina (formerly Coda) advertises itself as a “tweet-sized blockchain” that can be downloaded to a mobile phone even without much bandwidth. A node is just 22 KB. That’s a major contrast to more recognizable blockchains, such as Bitcoin and Ethereum. Those networks create lots of demand for their tokens but face logistical challenges to attract actual users that will secure and decentralize the network.

“There’s this whole notion, which is really a misconception when it’s applied to most projects, that, ‘Oh, we’re bringing decentralization to the world, we’re democratizing finance this way,’” she said. “But unless you are really getting your hands dirty, if you will, with the blockchain itself, and running a node and syncing the whole thing, then that’s kind of a problematic statement.”

As a board member of the just-created nonprofit Mina Foundation (which also welcomed crypto industry vets Josh Cincinnati, Tess Rinearson, Sean Inggs, and Evan Shapiro), Carlson will help create an ecosystem around the blockchain, primarily via grants.

She’s ready to get started helping the tiny blockchain project grow big: “This is what’s really exciting to me about the Mina Protocol, is making good on that promise that blockchain technology has had all along.”
