China could end up exceeding its emissions reduction targets as a result of carbon-intensive bitcoin mining, according to a study published this week. As a result, the nation's bitcoin carbon footprint is as big as one of its ten largest cities, the paper claims. Unlike most forms of currency — issued by a single entity like a central bank — bitcoin is based on a decentralized network and needs to be "mined. This takes place when bitcoin transactions, recorded on a public ledger called the blockchain, are "verified" by miners.

Plan sponsors Consultants Advisors. What is cryptocurrency, and does it have a place in your retirement portfolio? As digital currencies like Bitcoin continue to capture the attention of investors and the media, you may be wondering how cryptocurrency works and if it belongs in your investment portfolio. Below, TIAA provides its perspective on cryptocurrency and addresses important considerations for those who may be thinking about investing in the growing number of digital currencies. Unlike traditional currencies such as the U.
Instead, they are managed through a combination of peer-to-peer technology and software-driven cryptography. While Bitcoin is the most well-known cryptocurrency in use today, other names you may be familiar with include Dogecoin, Ethereum Ether , Litecoin and Polkadot. Each of these currencies are backed by digital code, versus a central authority government-issued currencies or a physical value like gold or silver. The code behind these decentralized networks is what allows users to trust each other in conducting transactions.
Open source blockchain developers constantly add to and refine the codebase. Introduced in , Bitcoin was the first among thousands of digital currencies that are distributed, traded and stored with the use of a decentralized ledger system, known as a blockchain. Blockchain is the key technology underpinning most cryptocurrencies. While blockchain technology can be used to store all kinds of information, its most common use is in recording cryptocurrency transactions.
Once a transaction is made, it's entered on this public ledger, which is managed by a decentralized global peer-to-peer network, typically comprised of millions of computers. In recent years, blockchain technology has become increasingly attractive to companies seeking secure ways to process payments, share medical and other sensitive data, and solve complex supply chain and logistics challenges.
Since each computer in the chain must verify a transaction before it can be noted in the register, the result is a chain of digital blocks that contain records of each transaction.
Each block is connected to all the blocks before and after it, making it difficult if not impossible to tamper with a single record. Someone intent on tampering with records would not only need to change the block containing a record, but all those linked to it. However, blockchain technology also has a downside. You may have seen stories about cryptocurrency mining in the news lately.
Mining refers to the complicated process by which new bitcoins are entered into circulation. It requires high-powered computers that solve complex mathematical puzzles to create a new "block" on the blockchain.
The mining process eats up a tremendous amount of computing power and electricity, which has led to concerns about bitcoin's environmental impact.
As investors are increasingly inundated with news about cryptocurrencies and potential applications for blockchain technology across business sectors and industries, many wonder if digital currency may be a suitable addition to their retirement portfolios. Canally, Jr. While all investable assets involve varying degrees of risk, as a group their relative risks are reasonably understandable over the longer term.
There is transparency in their make-up, and they are grounded in fundamental value. However, highly speculative assets, like cryptocurrency, are typically deficient in one or more of these attributes. They experience extreme volatility and therefore, are not useful as a store of value. At TIAA, our mission is to help participants achieve financial security to and through retirement. We believe this is achieved by saving through investable, as opposed to highly speculative, assets.
Cryptocurrencies exhibit extreme volatility with highly unstable correlations to other asset classes, making them almost impossible to model. They are not driven by the traditional supply and demand fundamentals that help determine the underlying value of other asset classes. This leads to a lack of transparency, increases the volatility of cryptocurrencies and makes them unreliable as an investable asset and as a store of value.
In addition, cryptocurrencies have no risk premium, do not produce income or cash flows, and have a short history. While the lack of a central governing authority such as a central bank is often cited by proponents of cryptocurrencies as a benefit, it can also exacerbate illiquidity and volatility. Daily volatility for digital currencies can run significantly higher than traditional markets and asset types.
A significant factor driving volatility is that there is no correct or intrinsic value for cryptocurrencies.
For investors in or approaching retirement, who will rely on income from their portfolios to meet their lifestyle expenses in retirement, the combination of nonexistent cash flow, increased volatility and lack of liquidity is highly problematic.
Cryptocurrency also has not proved to be a reliable hedge against stock market volatility. We saw a similar pattern following the global sell-off in stocks on July 19, , amid concerns about the spread of the COVID Delta variant. Yet, volatility is only one way investors can potentially lose money in cryptocurrency. If your private key an encrypted alphanumeric code that permits access to your Bitcoin or cryptocurrency holdings is lost or stolen, you no longer own the cryptocurrency, and you permanently lose those digital assets.
Your private key, which is picked randomly as soon as you make a wallet, is the only way to prove ownership. Although many people have made money with cryptocurrency, it remains a highly volatile and speculative investment. Today, tech stocks make up an important part of a well-diversified investment portfolio.
In addition, many companies that were household names in the s and early s no longer exist or were absorbed by other companies through mergers and acquisitions, such as Napster, Palm, Compaq and AOL. Until some of these factors change, investing in cryptocurrencies should be considered a highly speculative activity and not suitable for investment objectives that depend on the stability of the underlying value of the funds that investors commit to the investment.
If you're thinking about investing in cryptocurrency, as with any investment, it's important to do your research. Not all currencies are created equal, and some are higher risk than others.
Due to the myriad of risks associated with Bitcoin and other digital currencies, investments should only be made with assets set aside for speculative purposes. In other words, money you can afford to lose. Is it simply the fear of missing out or is there another investment challenge you are hoping to solve?

Crypto scams are on the rise: 5 ways to avoid them
Join us Thursday for a live coronavirus town hall on omicron, looking ahead and the impact on nursing homes. Find out more. But the prospect of quick riches can blind some people to the risks and enable crooks to lure them into scams. But unlike government-backed money, the value of virtual currencies is driven entirely by supply and demand. That can create wild swings that produce big gains for investors, or big losses. And crypto investments are subject to far less regulatory protection than traditional financial products like stocks, bonds and mutual funds. Cryptocurrency fraud has taken a quantum leap in recent years.
Best online brokers for buying and selling cryptocurrency in January 2022
Mark Zuckerberg probably is looking at the whole cryptocurrency wars and thinking to himself why he isn't getting a slice of that pie. Over the past three years, the Facebook creator had been trying to come forth with his own cryptocurrency but apparently his plans are failing miserably. The name of the project is Facebook Diem , and it had the potential on paper to truly get traction in the world of cryptocurrencies. Their intention was to create a cryptocurrency names Libra stablecoin that was announced all the way back in June 18, under the motto, 'move fast, break things'. What broke is the entire initiative as the entire project crashed completely this week. What Mark Zuckerberg didn't expect was the whole political backlash that Facebook as a company started getting frmo all over the place. In localized areas around the world, the platform was being used to promote right-wing specific agendas with Facebook accepting advertising money from political parties. This brought much politica opposition, financial fears and many allies to abandon the project due to the bad press. All sorts of regulatory blockades were put in place against Facebook and any project linked to them was doomed to fail.

Russian authorities draw up 'road map' to regulate cryptocurrencies -document
Representations of the virtual currency Bitcoin and Ethereum stand on a motherboard in this picture illustration taken May 20, MOSCOW, Jan 28 Reuters - Russian authorities have drawn up a 'road map' that envisages restrictions on cryptocurrencies but not a complete ban on trading and mining as advocated by the central bank, a document seen by Reuters showed on Friday. Politicians have pressed for a change of tack by the central bank, which has proposed restricting cryptocurrency trading and energy-intesive mining on Russian territory because of concerns it may cause financial instability. President Vladimir Putin has asked those involved to find a consensusand a working group, including the finance, economy, digital and interior ministries, the FSB security service, and the central bank, has been working on such a plan.
