NFTs are the latest cryptocurrency rage these days, with bands like Kings of Leon releasing their next album as limited edition “golden tickets,” and NBA digital collectibles being sold for millions of dollars. 

They’re interesting to collectors and cryptocurrency fans alike, but is there a future there? In other words: Should you spend some actual dollars to invest in a digital trinket?

What Are NFTs?

NFTs, or non-fungible tokens, are a type of cryptocurrency created on a smart contract platform such as Ethereum. They are unique digital objects that can be cool to own or even profitable to trade. Think of them as digital collectible cards. They typically start out as something only enthusiasts care about, but if you get a rare one, it could be worth a lot one day. 

What is fungible vs. non-fungible? 

Cryptocurrencies can be fungible, meaning all the currency’s units (i.e., tokens) are the same and equal, like grains of rice or dollars. 

Non-fungible tokens are the opposite — every cryptocurrency unit, or token, is unique and cannot be replicated. 

This “non-fungible” property can be used for many things, even certain types of currencies. But the current NFT craze is mostly fueled by digital art and collectibles. People have figured out that a unique, digital object can be interesting, cool, and even have a significant monetary value. It’s why the space has recently blossomed, encompassing thousands of projects involving artworks, gaming, and sports. 


How do NFTs work?

It really depends on the platform. But given the vast majority of NFTs are created and traded on Ethereum, we’ll focus on that. 

NFTs are created on Ethereum’s blockchain, which is immutable, meaning it cannot be altered. No one can undo your ownership of an NFT or re-create that exact same one. They’re also “permissionless,” so anyone can create, buy, or sell an NFT without asking for permission. Finally, every NFT is unique, and can be viewed by anyone. 

So yes — it’s like a unique collectible card in a forever-open store window that anyone can admire, but only one person (or cryptocurrency wallet, to be exact) can own at any given time. 

In a practical sense, an NFT is typically represented by a digital artwork, such as an image. But it’s important to understand that it’s not just that image (which can easily be replicated). Its existence as a digital object on the blockchain is what makes it unique. 

How do I buy or trade NFTs?

NFTs are bought and traded just like any other cryptocurrency based on Ethereum, only instead of buying some amount of tokens, you buy a single token. 

To do that, you should start by installing Metamask, a browser extension that lets you interact with various facets of Ethereum, such as exchanges and dApps (decentralized apps). MetaMask is also a digital wallet for Ethereum and all the tokens created on Ethereum (both fungible and non-fungible). 

After installing the extension, you should buy some Ethereum (you can do it directly in MetaMask with a debit card or Apple Pay by clicking on “Add Funds”). But be very careful with your funds — store your MetaMask password and your wallet’s private key somewhere safe. Then, when you visit a website that sells NFTs (such as NBA Top Shot) or an exchange where you can trade for them (such as Uniswap), connect your MetaMask wallet to the site (only do that on sites you know are safe), and buy your first NFT.  


Why do NFTs have value?

Of course, before you buy anything, you’ll probably want to know why it’s a good purchase. Indeed, why would anyone buy an NFT and why should there ever be a buyer willing to spend even more money down the line?

Ideally, the value of NFTs doesn’t just come from a game of digital hot potato, in which you purchase something hoping you’ll sell it for more later. And so on, until the whole thing crashes. Ideally, the NFT should be valuable to you because… you like it. If you’re an NBA fan, you might want to have an official NFT representing your favorite player. Or, perhaps there’s a digital cat that you really like.

Sure, in some ways, many NFTs are just a digital image that you can easily right-click and save to your computer. But NFTs also reside on the blockchain, which makes it extremely hard to truly copy them in their entirety. The blockchain entry also transparently tells you who created the NFT. If a famous musicians says: “Yes, that’s my Ethereum address that created this digital image of a possum.” Then that can be verified on the blockchain.

Some NFTs can be valuable in other ways. Say, for example, you buy an NFT related to an online game. Perhaps that NFT will one day give you special prestige in the game, or it could even be the basis for you getting some other, hard-to-get object; something that only you can have because every NFT is unique. If you’ve ever played World of Warcraft or a similar game, you know how valuable a piece of armor or a weapon can be. Now, with NFTs, no one can take it away from you, not even the game’s owners. 

Let’s return for a second to that game of digital hot potato. NFTs are a nascent space, and there’s a lot of hysteria and scamming going on. You might see a certain NFT sold for millions, and think you’ll also be able to buy something for a few dollars and become rich selling it to someone later on. It can happen, but it’s rare. And these things can be manipulated. For example, a cryptocurrency whale (someone that owns vast amounts of crypto money) can buy many NFTs and then “sell” them to himself (his other cryptocurrency address) for millions, artificially inflating the price. So be careful: Just because some NFT was traded for a lot of money, do not think this automatically means all other similar NFTs are valuable as well. 


What are the most expensive NFTs?

In the early days of the space, we saw a blockchain game like CryptoKitties sell virtual cats for tens or even hundreds of thousands of dollars. Recently, music producer 3LAU sold a collection of 33 limited edition NFTs for more than 11 million dollars. The musician Grimes (aka the mother of little X Æ A-Xii) even sold her digital art collection for $7,500 apiece, totaling $6 million in sales. Yes, these things can get very pricey. 

Are NFTs a good investment?

Buying an NFT because you like it, or maybe even to earn (or lose) a few quick bucks is one thing. But investing in NFTs is another. Again, it’s a nascent space. Even a Van Gogh painting or a rare Babe Ruth baseball card required some passage of time before becoming very valuable. 

Given the digital nature of NFTs, it’s hard to compare them to prized physical artworks, such as statues and paintings. On the other hand, we live in a world where one Bitcoin is worth more than $50,000, so things from the digital realm can certainly be very valuable and even sustain that value over longer periods of time. 

In any case, if you plan to invest in NFTs, you’ll need to dive deep into this complex world because each NFT market is slightly different. It’s also pricey — trading on Ethereum can be quite costly as the network’s recent congestion is causing fees to rise. Finally, you’ll need to think strategically and follow the often rapidly changing cryptocurrency trends. 

In short, it’s possible to earn money by investing in NFTs, but you’ll have to do your homework.

Air Canada signs C$5.9 billion government aid package, agrees to buy Airbus, Boeing jets

Published

 on

By David Ljunggren and Allison Lampert

OTTAWA/MONTREAL (Reuters) -Air Canada, struggling with a collapse in traffic due to the COVID-19 pandemic, reached a deal on Monday on a long-awaited aid package with the federal government that would allow it to access up to C$5.9 billion ($4.69 billion) in funds.

The agreement – the largest individual coronavirus-related loan that Ottawa has arranged with a company – was announced after the airline industry criticized Prime Minister Justin Trudeau’s Liberal government for dawdling. The United States and France acted much more quickly to help major carriers.

Canada‘s largest carrier, which last year cut over half its workforce, or 20,000 jobs, and other airlines have been negotiating with the government for months on a coronavirus aid package.

In February, Air Canada reported a net loss for 2020 of C$4.65 billion, compared with a 2019 profit of C$1.48 billion.

As part of the deal, Air Canada agreed to ban share buybacks and dividends, cap annual compensation for senior executives at C$1 million a year and preserve jobs at the current level, which is 14,859.

It will also proceed with planned purchases of 33 Airbus SE 220 airliners and 40 Boeing Co 737 MAX airliners.

Chris Murray, managing director, equity research at ATB Capital Markets, said the deal took into account the “specific needs of Air Canada in the short and medium term without being overly onerous.”

He added: “It gives them some flexibility in drawing down additional liquidity as needed.”

Transport Minister Omar Alghabra said the government was still in negotiations with other airlines about possible aid.

Canada, the world’s second-largest nation by area, depends heavily on civil aviation to keep remote communities connected.

Opposition politicians fretted that further delays in announcing aid could result in permanent damage to the country.

Air Canada said it would resume services on nearly all of the routes it had suspended because of COVID-19.

‘SIGNIFICANT LAYER OF INSURANCE’

The deal removes a potential political challenge for the Liberals, who insiders say are set to trigger an election later this year.

The government has agreed to buy C$500 million worth of shares in the airline, at C$23.1793 each, or a 14.2% discount to Monday’s close, a roughly 6% stake.

“Maintaining a competitive airline sector and good jobs is crucially important,” Finance Minister Chrystia Freeland told reporters, adding the equity stake would allow taxpayers to benefit when the airline’s fortunes recovered.

The Canadian government previously approved similar loans for four other companies worth up to C$1.billion, including up to C$375 million to low-cost airline Sunwing Vacations Inc. The government has paid out C$73.47 billion under its wage subsidy program and C$46.11 billion in loans to hard-hit small businesses.

Michael Rousseau, Air Canada‘s president and chief executive officer, said the liquidity “provides a significant layer of insurance for Air Canada.”

Jerry Dias, head of the Unifor private-sector union, described the announcement as “a good deal for everybody.”

Unifor represents more than 16,000 members working in the air transportation sector.

But the Canadian Union of Public Employees, which represents roughly 10,000 Air Canada flight attendants, said the package protected the jobs of current workers rather than the 7,500 members of its union who had been let go by the carrier.

U.K. advises limiting AstraZeneca in under-30s amid clot worry

Published

 on

LONDON —
British authorities recommended Wednesday that the AstraZeneca COVID-19 vaccine not be given to adults under 30 where possible because of strengthening evidence that the shot may be linked to rare blood clots.

The recommendation came as regulators both in the United Kingdom and the European Union emphasized that the benefits of receiving the vaccine continue to outweigh the risks for most people — even though the European Medicines Agency said it had found a “possible link” between the shot and the rare clots. British authorities recommended that people under 30 be offered alternatives to AstraZeneca. But the EMA advised no such age restrictions, leaving it up to its member-countries to decide whether to limit its use.

Several countries have already imposed limits on who can receive the vaccine, and any restrictions are closely watched since the vaccine, which is cheaper and easier to store than many others, is critical to global immunization campaigns and is a pillar of the UN-backed program known as COVAX that aims to get vaccines to some of the world’s poorest countries.

“This is a course correction, there’s no question about that,” Jonathan Van-Tam, England’s deputy chief medical officer, said during a press briefing. “But it is, in a sense, in medicine quite normal for physicians to alter their preferences for how patients are treated over time.”

Van-Tam said the effect on Britain’s vaccination timetable — one of the speediest in the world — should be “zero or negligible,” assuming the National Health Service receives expected deliveries of other vaccines, including those produced by Pfizer and Moderna.

EU and U.K. regulators held simultaneous press conferences Wednesday afternoon to announce the results of investigations into reports of blood clots that sparked concern about the rollout of the AstraZeneca vaccine.

The EU agency described the clots as “very rare” side effects. Dr Sabine Straus, chair of EMA’s Safety Committee, said the best data is coming from Germany where there is one report of the rare clots for every 100,000 doses given, although she noted far fewer reports in the U.K. Still, that’s less than the clot risk that healthy women face from birth control pills, noted another expert, Dr. Peter Arlett.

The agency said most of the cases reported have occurred in women under 60 within two weeks of vaccination — but based on the currently available evidence, it was not able to identify specific risk factors. Experts reviewed several dozen cases that came mainly from Europe and the U.K., where around 25 million people have received the AstraZeneca vaccine.

“The reported cases of unusual blood clotting following vaccination with the AstraZeneca vaccine should be listed as possible side effects of the vaccine,” said Emer Cooke, the agency’s executive director. “The risk of mortality from COVID is much greater than the risk of mortality from these side effects.”

Arlett said there is no information suggesting an increased risk from the other major COVID-19 vaccines.

The EMA’s investigation focused on unusual types of blood clots that are occurring along with low blood platelets. One rare clot type appears in multiple blood vessels and the other in veins that drain blood from the brain.

While the benefits of the vaccine still outweigh the risks, that assessment is “more finely balanced” among younger people who are less likely to become seriously ill with COVID-19, the U.K’s Van-Tam said.

“We are not advising a stop to any vaccination for any individual in any age group,” said Wei Shen Lim, who chairs Britain’s Joint Committee on Vaccination and Immunization. “We are advising a preference for one vaccine over another vaccine for a particular age group, really out of the utmost caution rather than because we have any serious safety concerns.”

In March, more than a dozen countries, mostly in Europe, suspended their use of AstraZeneca over the blood clot issue. Most restarted — some with age restrictions — after the EMA said countries should continue using the potentially life-saving vaccine.

Britain, which relies heavily on AstraZeneca, however, continued to use it.

The suspensions were seen as particularly damaging for AstraZeneca because they came after repeated missteps in how the company reported data on the vaccine’s effectiveness and concerns over how well its shot worked in older people. That has led to frequently changing advice in some countries on who can take the vaccine, raising worries that AstraZeneca’s credibility could be permanently damaged, spurring more vaccine hesitancy and prolonging the pandemic.

Dr. Peter English, who formerly chaired the British Medical Association’s Public Health Medicine Committee, said the back-and-forth over the AstraZeneca vaccine globally could have serious consequences.

“We can’t afford not to use this vaccine if we are going to end the pandemic,” he said.

In some countries, authorities have already noted hesitance toward the AstraZeneca shot.

“People come and they are reluctant to take the AstraZeneca vaccine, they ask us if we also use anything else,” said Florentina Nastase, a doctor and co-ordinator at a vaccination centre in Bucharest, Romania. “There were cases in which people (scheduled for the AstraZeneca) didn’t show up, there were cases when people came to the centre and saw that we use only AstraZeneca and refused (to be inoculated).”

Meanwhile, the governor of Italy’s northern Veneto region had said earlier Wednesday that any decision to change the guidance on AstraZeneca would cause major disruptions to immunizations — at a time when Europe is already struggling to ramp them up — and could create more confusion about the shot.

“If they do like Germany, and allow Astra Zeneca only to people over 65, that would be absurd. Before it was only for people under 55. Put yourself in the place of citizens, it is hard to understand anything,” Luca Zaia told reporters.

The latest suspension of AstraZeneca came in Spain’s Castilla y Leon region, where health chief Veronica Casado said Wednesday that “the principle of prudence” drove her to put a temporary hold on the vaccine that she still backed as being both effective and necessary.

French health authorities had said they, too, were awaiting EMA’s conclusions, as were some officials in Asia.

On Wednesday, South Korea said it would temporarily suspend the use of AstraZeneca’s vaccine in people 60 and younger. In that age group, the country is only currently vaccinating health workers and people in long-term care settings.

The Korea Disease Control and Prevention Agency said it would also pause a vaccine rollout to school nurses and teachers that was to begin on Thursday, while awaiting the outcome of the EMA’s review.

But some experts urged perspective. Prof Anthony Harnden, the deputy chair of Britain’s vaccination committee, said that the program has saved at least 6,000 lives in the first three months and will help pave the way back to normal life.

“What is clear it that for the vast majority of people the benefits of the Oxford AZ vaccine far outweigh any extremely small risk,” he said. “And the Oxford AZ vaccine will continue to save many from suffering the devastating effects that can result from a COVID infection.”
