Bitcoin: How High Can Bitcoin's Price Go in ? | Fortune

She believed that loving a person would be a safer bet than investing in a cryptocurrency she could neither touch nor understand.

Cryptocurrencies could lead to significant losses in tax revenue. He is a populist president, but if he attends the World Economic Forum a big if, given the government shutdown , will he provoke division or stress unity? The virtual currency has enjoyed a spectacular rise in value, but there are important tax implications. The price of one Bitcoin is down 50 percent from its peak as concerns grow that governments may crack down on virtual currency trading.

Stocks have risen for so long and with such steadiness that Wall Street is becoming nervous. For insight, check out our quarterly report on investing. That may not mean a big split. Digital collectibles underpinned by blockchain technology are rising and falling in value at a far faster rate than just about everything in the analogue art world. These rules produced two somewhat predictable results, especially coming in the immediate wake of the financial crisis and the government bailouts of the big banks.

The limited and regular release of Bitcoins appealed to libertarians, who have been skeptical of currencies that governments can print in unlimited quantities. The built-in sense of scarcity also led people to regard Bitcoin as a kind of digital gold, its value likely to increase over time — in other words, something to buy and sell as a speculative investment. At the same time, that speculative activity has left much of the general public wondering why these virtual coins should be worth anything at all.

Bitcoin digital tokens are part of a new kind of online financial network, which runs on the computers of those who use the virtual currency. People who join and support the network — hosting its open-source software, serving as record-keepers of sorts — receive new Bitcoins as they are released in a kind of recurring lottery, thus encouraging user participation.

The details of how the network operates can be mind-numbingly complicated, involving lots of advanced math and cryptography, but at the most basic level, the network makes it possible for the first time to send valuable digital money around the world almost instantly, without moving through an intermediary like a bank or credit-card company or a service like PayPal.

In a sense, the Bitcoin network was designed to be a financial version of email, which enables messages to be delivered without passing through a national postal service, or like the broader Internet itself, which allows people to publish news and essays without going through a media company.

Instead of just delivering words, though, the Bitcoin network makes it possible to deliver money from New York to Shanghai in a matter of minutes without paying any financial institution.

The number of Bitcoin users in Argentina is relatively small; it barely registers on most charts of global Bitcoin usage. But Argentina has been quietly gaining renown in technology circles as the first, and almost only, place where Bitcoins are being regularly used by ordinary people for real commercial transactions.

A number of large American companies have started accepting Bitcoin payments, but so far there has been little economic incentive for their customers to pay with Bitcoins. In contrast, the best-known Bitcoin start-up in Argentina, BitPagos, is helping more than hotels, both cheap and boutique, take credit-card payments from foreign tourists.

The money brought to Argentina using Bitcoin circumvents the onerous government restrictions on receiving money from abroad. Castiglione has some hotel clients, but he says that many of his or so registered customers are freelancers who use Bitcoin to get paid by overseas clients, or companies that want to move money in and out of Argentina.

A popular new online retailer, Avalancha, began accepting Bitcoin last summer and has seen the volume of Bitcoin transactions grow steadily since then. Avalancha offers customers a 10 percent discount when they use the virtual currency, because accepting credit cards generally ends up costing Avalancha more than 10 percent as a result of the vagaries of the Argentine financial system.

Bitcoin proponents like to say that the currency first became popular in the places that needed it least, like Europe and the United States, given how smoothly the currencies and financial services work there. It makes sense that a place like Argentina would be fertile ground for a virtual currency.

At the end of , for example, the peso was worth 25 percent less than it was at the beginning of the year. And that adversity pales in comparison with past bouts of hyperinflation, defaults on national debts and currency revaluations. Less than half of the population use Argentine banks and credit cards. Wences Casares grew up on a remote sheep ranch in Patagonia and now lives on an estate looking out over Silicon Valley. He is, as much as anyone, responsible for making Bitcoin known in both Argentina and the United States.

He sold his next big company, an online bank, to Banco Brasil. By the time he first heard about Bitcoin, in late , he was in his first year of his latest start-up, Lemon, a mobile wallet for smartphones, not unlike Apple Pay, which came out three years later.

His fascination with Bitcoin had less to do with professional experience, however, than a childhood spent in a country whose financial system seems to be terminally broken. In , after years of inflation, the government created the new peso: In , the new peso, its value eroded by inflation, was in turn supplanted by the austral, worth 1, new pesos. Eventually the government went back to the peso, this time pegged to the dollar, an effort that also failed.

This is the street-smart economics. Not the complex Ph. His mother carried two grocery bags filled with cash — the salary she had just been paid. She rushed with Casares and his sisters to the grocery store and made them run through the aisles, grabbing as much food as they could before the prices changed. An employee walked through the store all day doing nothing but re-pricing the goods on the shelves to keep up with the rapidly changing value of the peso.

After paying at the register, Casares and his sisters ran back for more food to spend the leftover money on. In this hyperinflationary environment, holding on to pesos was the same thing as losing money. Whatever savings accumulated were quickly exchanged for dollars, which held their value better than pesos. In , Casares and five friends bought a school bus and drove it on a three-week road trip from Buenos Aires, the capital, to Tierra del Fuego, at the southern end of South America.

After the vehicle was stolen upon their return, the friends vowed to buy a second bus for another trip. The friends who lived in Argentina quickly paid their shares to purchase and fix it up, but Casares stalled, knowing how much it cost in time and fees to move money from the United States to Argentina. Then Restelli told him that Bitcoin might be just the answer. At the time, the virtual currency had a small cult following in the United States and was essentially unheard-of in Argentina, but Restelli had read about it on an American tech blog.

Casares sent Restelli the Bitcoins that evening. Casares was fascinated by the transaction. Here was money that anyone could buy online and that promised to hold its value better than the peso.

That promise would later be tested by extreme price swings. Even Casares, who created his first start-up in the country, had never held an Argentine bank account. He sent articles about Bitcoin to his bus-trip friends and explained how easy it was to move thousands of dollars in and out of Argentina. One friend went on to found the central Bitcoin advocacy group in Argentina and opened the Bitcoin Embassy in Buenos Aires. Casares began stockpiling Bitcoins, and when he visited Argentina during , he posted offers to sell them on an Internet message board that was becoming a small, impromptu national marketplace for the virtual currency.

He organized the first Bitcoin Meetup in Argentina in December , though only a handful of people besides Restelli showed up at the whiskey bar where it was held.

He had come to believe that the advantages of its network would push the value of each Bitcoin to astronomical values, just as slivers of the airwave spectrum increased in worth as more communication companies sought to use it. In the meantime, each Bitcoin could serve as an easy, secure place to store money, comparable to gold. But Casares explained how places like Argentina were different.

His first big convert among his friends, and the one whose opinion in this area mattered the most, was David Marcus, who had recently become the president of PayPal. At dinner the first night, Casares won the attention of a table full of investors by describing his childhood experiences in Argentina and how Bitcoin equipped people to avoid similar situations.

During the next two days of the conference, a steady stream of attendees who had seen or heard about the Sunday-evening conversation approached Casares, including Reid Hoffman, the co-founder of LinkedIn. At the time, Casares was still running his mobile-wallet start-up and had no business stake connected to Bitcoin beyond his own holdings of the virtual currency, which had become substantial.

He urged his friends to make their own purchases. And nothing drives prices up like scarcity. In the eyes of some supporters, these advantages add up to virtually unconstrained upside.

It would hardly be the first craze that fizzled fast. Hockett sees echoes of that disaster in Bitcoin-mania. After a securities regulator warned that people were taking out mortgage loans to speculate on Bitcoin, he noted the irony: Hockett believes blockchain tech will prove a game-changer. As the original cryptocurrency, Bitcoin suffers from drawbacks typical of first-generation technology. And the entire network can currently handle, at most, only seven transactions per second, compared to the thousands that Visa and Mastercard process in the same span.

Jim Rickards, chief strategist at Meraglim, a financial analytics firm, views Bitcoin with equal fatalism. When British scientists first encountered the platypus in the late 18th century, they suspected a hoax.

Plus, it was venomous and laid eggs. Bogart is deploying a favorite analogy: When skeptics dismiss Bitcoin, bulls like Bogart push back. Unlike gold, Bitcoin is not static.

The software code is under constant development. For many, this is reason enough to play the long game. Most of the earliest investors seem to be doing just that. Since moving to an exchange is a rough proxy for an intention to sell, this suggests the vast majority are keeping their windfall in reserve.

There are many reasons, of course, to take the wait-and-see approach with Bitcoin—from the fact that it could be worth double tomorrow, to the reality that there are currently few nonspeculative ways to actually spend or use it. The wealth management giant Fidelity, for one, allows employees to buy lunch with Bitcoin in the company cafeteria, but so far the program has been a dud.
