Half a billion dollars’ worth of cryptocurrency was stolen—that’s gotten people’s attention.

The plunder of more than $500 million worth of digital coinsfrom the Japanese cryptocurrency exchange Coincheck last week has added to a growing perception that cryptocurrencies are particularly vulnerable to hackers.It’s an expensive reminder that like many things in the cryptocurrency world, security technologies—and the norms, best practices, and rules for using them—are still emerging.


Not least because of its enormous size, the  Coincheck hack could go down as a seminal moment in that process.This piece first appeared in our new twice-weekly newsletter Chain Letter, which covers the world of blockchain and cryptocurrencies. Sign up here – it’s free!


First, hackers laid bare the fact that Coincheck had opted not to implement some basic security measures.


The company’s executives told news reporters that the stolen coins had been stored in an internet-connected “hot” wallet. It’s far more secure to keep funds offline, in “cold” storage—often hardware specially designed for the task. Many exchanges already claim in their marketing material that they hold the vast majority of their users’ funds offline. Going forward, this will presumably become standard practice.

Blockchains Are Poised to End the Password Era


Many technologists think blockchains can revolutionize how we keep track of our identities.


With that taken care of, there’s a more weighty question on the table. Every public cryptocurrency address is associated with a private key; without it, money can’t be moved from that address.


Someone who manages to acquire your private key, though, can send your money away. That’s what happened in the Coincheck heist.


So how do we make the private cryptographic keys owners need to access their coins more secure?

One answer, known as a multisignature address, is conceptually simple: a “multisig” requires more than one cryptographic key in order execute a transaction. It’s a bit like the multifactor authentication process you may use to access your e-mail account.


Business partners can use multisig technology to, for example, create a wallet that requires each of them to sign off on transactions. That would make it substantially more difficult for hackers to access funds.Of course, multisig is not a silver bullet. In 2016, for example, hackers defeated a multisig system to steal $65 million from Bitfinex, one of the world’s largest exchanges.


How exactly the perpetrators managed the feat isn’t clear, but it’s possible there was a flaw in the specific implementation.


Should financial regulators require exchanges to use multisig technology to secure any funds they keep in a hot wallet? Japanese officials are conducting an emergency security review of the country’s exchanges, and that might be a measure they consider.


Either way, a broader discussion about blockchain security is just beginning.


Some say blockchains can revolutionize how we track a host of assets beyond just money, like land titles. Such a system might look different from the blockchain networks running today’s cryptocurrencies, but it would still rely on cryptographic keys that could fall into the wrong hands.


The techniques and processes we adopt for securing them will be crucial for keeping hackers from running off with land that isn’t theirs.

January was a painful time for many bitcoin investors.At the start of the month, a digital coin was worth nearly $15,000. By the end, it was worth around $9,000. (On the first day of February, the currency continued to hover near the $9,000 mark, a critical level that analysts are watching.)


The losses stem in part from new regulations in South Korea and Facebook's announcement that it would ban ads for the digital currencies. More volatility is expected.



Owning an asset that's been called both a fraud and the future can be an emotionally intense experience.When bitcoin lost 30 percent of its value on Dec. 22, for example, one post on Reddit read: "I just re-financed my house to get in.


I'm freaking out." Another user offered support to the frantic: "If anyone's actually depressed or suicidal, come to r/SuicideWatch. We love to listen and talk there.


"It's the 24-hour cycle of cryptocurrencies that can wear on people's nerves, said Jim Smigiel, CIO of absolute return strategies at SEI Investments."With other speculative investments, like private equity and venture capital, you can't check your phone every five minutes," he said. With cryptocurrencies, "You're able to track the minute-by-minute value of it."


"Looking at something with such high volatility all the time is not conducive to an investor's mental health," Smigiel said.




Iconic investor Warren Buffett on bitcoin, his health and the state of markets  11:16 AM ET Wed, 10 Jan 2018 | 03:42Here's how to keep calm on the cryptocurrency roller coaster:

Look away

Bitcoin's volatility is part of what makes it irresistible, said Willemien Kets, associate professor at the University of Oxford's Department of Economics."We know from social psychology that the best way to get people hooked on something is to give them a reward on a very uncertain time frame," Kets said.


Don't fall into the trap.


Checking the value of cryptocurrencies constantly is unproductive, Kets said."You can't do anything about the price movement itself," she said.Instead she recommends people decide on a price point at which they'll sell — say, if the asset drops below $10,000 — and set their phone to alert them at that threshold.

An attendee wearing a t-shirt decorated with a bitcoin rocket illustration and the words 'To the Moon' checks his smartphone at the CrytoSpace conference in Moscow, Russia, on Friday, Dec. 8, 2017.


Jack Tatar, co-author of "Cryptoassets: The Innovative Investor's Guide to Bitcoin and Beyond," pointed to another reason why constant phone checks are futile."It's very hard to realize the gains you see on your phone," Tatar said. "These markets are not as liquid as the stocks and bond market.


You can check your phone and see you're up to $30,000, but if you wan't to realize that gain, you probably won't be able to do that."That's because it can take days for a cryptocurrency transaction to complete, during which the value can change substantially. 


Despite his advice, Tatar admitted he, too, can't look away."My son has tried to tell me to take a few days off," he said. "But I just can't."

Buy to hold

When people buy and sell in a dizzied cycle, they miss the bigger picture of cryptocurrencies and the blockchain technology on which it's traded, said financial advisor Ric Edelman, founder and executive chairman of Edelman Financial Services.


"There's no question that digital currencies are the future," Edelman said. "You should be prepared to own it for years."He said his decision to hold bitcoin for more than a decade has paid off."I've watched it go from $1 to $1,000, back to $200 and then to $16,000," he said.


Although he acknowledged that such ups and downs are intolerable for some people."If owning this asset is causing you to stare at the ceiling at night, you shouldn't own it," he said. "There's more to life than money."

"I've watched it go from $1 to $1000, back to $200 and then to $16,000."-Ric Edelman , financial advisor 

Peter Ayton, who studies behavioral decision theory at the City University of London, said it's hard to expect people to be rational with cryptocurrencies. Many people who've been seduced by bitcoin are individuals who might not fully understand what they're buying, he said."When you have something as volatile as bitcoin, it doesn't lend itself to long-term strategic thinking," Ayton said.

Diversify beyond bitcoin

Michael Sonnenshein, investments director at cryptocurrency firm Grayscale, said people might be less anxious if they're not banking on just one cryptocurrency.Fortunately, you don't have to: There are currently some 2,000 cryptocurrencies to chose from. And more investment firms are looking into establishing index funds for cryptocurrencies.


For example, Grayscale is soon launching a "basket of digital currencies," in which investors' money will be spread across five digital currencies.Diversifying is useful for another reason, Edelman said: "It's so early, we don't know which cryptocurrencies will survive."

Invest only what you can afford to lose

Tatar said people must restrict how much of their investments go to cryptocurrencies."You're seeing too many people jumping in and betting the ranch, and just saying 'yee-haw!'" he said. "They're not disciplined enough to realize they have to stay within their asset allocation models.


""Rebalancing" your investments is essential with cryptocurrencies, he said, because of their tendency to rapidly change value."If you've invested 20 percent of your portfolio into bitcoin, and all of a sudden you check and, lo and behold, your bitcoins have increased so much that they're now 35 percent of your portfolio, you can rebalance and go back to your asset allocation," Tatar said. "That should protect you from some of that volatility."

"You're seeing too many people jumping in and betting the ranch, and just saying Yee-Haw!"-Jack Tatar , co-author, Cryptoassets: The Innovative Investor's Guide to Bitcoin and Beyond

It's not just the owners of cryptocurrencies who are stressed, Smigiel said. Recently, he finds himself consoling his clients who haven't bought any bitcoin, ripple or ethereum.


"We also see anxiety on the flip side — the people who feel they are missing out," he said. "And so you're anxious either way."More from Personal Finance:

Say goodbye to ads like “Richard Branson Reveals Trading Bitcoins Will Make You Quit your job in 30 Days!” #ICO #Bitcoin #Ethereum


Originally posted on January 30, 2018, at 7:00 p.m.Updated on January 30, 2018, at 7:19 p.m.


By Ryan Mac (BuzzFeed News Reporter) Jane Lytvynenko (BuzzFeed News Reporter) Alex Kantrowitz (BuzzFeed News Reporter)



Facebook is banning ads that promote bitcoin and other cryptocurrencies in an effort to protect its users from “financial products and services frequently associated with misleading or deceptive promotional practices.


"The platform has recently been criticized for hosting dubious cryptocurrency-related ads, some that appeared to promote get-rich quick schemes and potential scams. Earlier this month, BuzzFeed News highlighted how some of these Facebook ads peddled bitcoin-related disinformation and fake news touting their services and Initial Coin Offerings (ICOs).


“We want people to continue to discover and learn about new products and services through Facebook ads without fear of scams or deception,” Robert Leathern, a Facebook product management director, said in a company blog post.


“That said, there are many companies who are advertising binary options, ICOs and cryptocurrencies that are not currently operating in good faith.”Among the ads targeted, those from "crypto-genius" James Altucher, a digital currency evangelist who's been featured on media outlets like CNBC. Altucher has not yet responded to a request for comment.


"Arguably it was a poor ad review process that let these ads through in the first place."


Gavin Sheridan, CEO of legal startup Vizlegal, welcome Facebook's move — with a few caveats. "The adage to trust what people do - not what they say - holds true, as ever," he told BuzzFeed News. "In effect, Facebook already bans many of these sorts of deceptive ads - often placed by advertisers that redirect to websites made to look like news providers such as CNN, that in turn lead to websites that seek to obtain credit card details - often in situations where users have no idea what they are buying.


Arguably it was a poor ad review process that let these ads through in the first place."


The move to police shady ICO ads comes as Facebook works to fix its platform, which has routinely been exploited by bad actors, from scam artists to fake news purveyors to foreign governments seeking to upend US politics. In the past few weeks, Facebook announced significant changes to its News Feed intended to limit the reach of untrustworthy news sources while boosting local news outlets and posts from friends and family.


Just how well Facebook will enforce the policy it just announced is a curious question. Last year, for example, ProPublica reported that Facebook allowed advertisers to exclude users by race. Last February, following that report Facebook vowed to crack down on discriminatory ads, but when ProPublica followed up in November, they were still able to purchase advertising that wouldn’t be shown to African Americans, people who need wheelchair ramps, and even Jews, among others.


“We may not catch every ad that should be removed under this new policy,” the Facebook announcement said.It’s not clear whether the policy has already been enforced, but some of the types of advertisements Facebook intends to target are still on the platform.


A Facebook spokesperson confirmed that James Altucher's ads will no longer be allowed, but an unverified page using Altucher’s name, for example, is still promoting advertisements for “New must-own cryptocurrencies could turn as little as $10 into a fortune.


” The ads lead to a website that looks to sell Altucher’s “Masterclass on Cryptocurrencies.”“If you follow my script below, you could turn $100 into a retirement fortune in the next 12 months… while minimizing your risk,” says the banner at the top.

I cover Wealth Preservation in its legal permutations  Opinions expressed by Forbes Contributors are their own.



A company called Bitconnect, which is different than Bitcoin, has recently been made the subject of a class-action lawsuit alleging that it was a Ponzi scheme. The investors say that they collectively lost over $771,000 in their investment in the company and other damages. Bitconnect purportedly had a market capitalization of $2.6 million on January 6, 2018, but was of this writing about three weeks later, it is down to $128 million.


You can read more about the Bitconnect lawsuit here.Next, according to another story you can read here, Tokyo-based Coincheck, Inc., reportedly lost somewhere around a half billion dollars' worth of its customer's blockchain tokens (a form of crytpocurrency) to hackers.



But as big as these numbers are, they pale in comparison to the research paper entitled "Price Manipulation In The Bitcoin Ecosystem" as published in the Journal of Monetary Economics that one person was able to manipulate the price of Bitcoin in 2013 from $150 to $1,000. Meanwhile, one of my readers sent me a link to an article found here which suggests that there is significant price manipulation of Bitcoin going today. (Well, no duh.)

The Bitcoin Bubble


So, in a single week we are presented with reports of significant fraud, theft, and price manipulation in the cryptocurrency markets. This is hardly investment Utopia, and sadly it seems that most of the folks who are having their shirts stolen in crypocurrency are those who can least afford to lose it.


In fact, there is increasing evidence that many of the Bitcoin and other cryptocurrency investors are not just gambling with money they can't afford to lose, but they are gambling with money they don't even have -- by purchasing cryptocurrencies by taking advances on their credit cards.


All of this has made cryptocurrencies horrendously volatile -- their trading charts look the waves of a Bering Sea storm (with the exception of Bitconnect and a few others which looks like that cliff which Wiley E. Coyote always falls from).



These bad things happen with governmental currencies too, but in a much, much lesser degree because those currencies are subject to government regulation and oversight. Take the dollar, for example. The dollar is just a little piece of paper, but it is subject to oversight by the U.S. Treasury, the Federal Reserve, among others. Behind the U.S. Treasury and the Federal Reserve is the U.S. Department of Justice and other law enforcement apparatus, such as the IRS Criminal Investigations branch.


A private individual or group which attempts to significantly manipulate the U.S. dollar would find the full weight of the U.S. government coming after them and fast.The U.S. is hardly unique in this regard. All governments, through their Finance Secretaries or Central Banks or whatever, carefully regulate their currencies.


It is this regulation that causes the currency to be treated with some degree or another of predictability, i.e., currencies move in relation to the markets and to each other, but these moves are typically at much more of a glacial pace -- routine daily swings of 10% or 20% just don't happen (yes, sometimes a currency will crater, such as Iraqi dinars, but not on a daily basis)....

"We look at ethereum like AOL or Myspace."That's how Mobius Network co-founder and CEO David Gobaud explains why his startup ran its initial coin offering (ICO) on the Stellar network instead of ethereum, the most popular blockchain for token sales.


The comment underscores the growing interest in some corners of the crypto community for faster and cheaper payment rails as ethereum, like bitcoin, struggles to scale.


Mobius announced Thursday that it has raised $39 million in the ICO — one of the larger recent token sales and the largest by far on the Stellar platform.


The company accepted only Stellar's native currency, lumens (XLM), in exchange for its own token, known as mobi.According to Mobius, the sale hit its $39 million hard cap after only two hours, selling 35 percent of the total 888 million mobi tokens.

Participants in the round included China's Angel Chain Capital, Nirvana Capital and WaltonChain, an internet of things (IoT) startup that is building devices to enable manufacturers and retailers to track supply chains, according to the firm's website.In addition to this backing, Gobaud emphasized that Mobius deployed its decentralized app (dapp) store alongside its ICO, saying it was important for the company to come out with live code early, to prove the project was real.


But what's perhaps most striking about the sale was the choice of blockchain.While latency or cost might not be a dealbreaker for some blockchain projects, they are for Mobius' use case. Its thesis is that traditional tech companies will soon want to integrate with cryptocurrencies and, eventually, a decentralized web.


Mobius' white paper compares the company's work to that of Stripe, the Silicon Valley darling that took integration of credit card payments down to a few lines of code (and incubated Stellar in its early days). Mobius aims to do the same thing for cryptocurrency payments and, down the line, for publishing data to trade on decentralized marketplaces.


So the company needed an IoT-friendly network that could handle large amounts of transactions and data quickly, with low or no fees.The goal is to "make it easy to connect every device, developer and data stream to the blockchain ecosystem," Gobaud said.

Yet while the vast majority of ICO-funded projects have been run on top of ethereum, using the ERC-20 standard, that blockchain has suffered from transaction backlogs and pendulum-like swings in fees.


Hence, after beginning its project on ethereum, Mobius switched to Stellar, the protocol created by Ripple co-founder Jed McCaleb. Like Ripple before it, Stellar was designed specifically for frictionless payments.

Trade-offs

Ethereum's scaling challenges have become acute in recent months. The issue moved Kik to announce that it would move its kin token off ethereum in December 2017.While the ethereum developers recognize and are working on the problem, the Mobius team couldn't wait for a scaling solution, Gobaud said."We were building our dapp store on ethereum and then we connected with Jed," he said adding:

"We realized there was no way that ethereum could handle our technology. It was too slow, too expensive and too insecure. ... We see all these other projects with these immense problems"

Gobaud highlighted the problems with safely deploying smart contracts. "They are Turing complete programs, but they are really hard to write," he said, pointing to the first and second multi-million-dollar ether losses on Parity.


Solidity was not a language built with security in mind, Gobaud argued.In Stellar, "we think we've uncovered this underutilized, really unknown technology," Gobaud said.


For example, Stellar supports multi-signature wallets at the protocol level, making custodianship much easier for developers.But Stellar has its downsides, Gobaud acknowledged. It's not Turing complete, for example, but Mobius is happy to make that trade-off in exchange for vastly faster and cheaper transactions.

What's next?

The white paper discusses a lot of use cases for the mobi token and its protocol, but the easiest one to explain is payments.For anyone who believes that cryptocurrency will become more and more appealing to online businesses, the company that makes transacting in crypto easy the fastest stands to recoup benefits with a long tail.

If Mobius can make accepting crypto payments a matter of adding a few lines of code, that would be compelling if online companies begin accepting cryptocurrency more widely.


Talking to Gobaud, though, payments seems more like a way to sell the traditional internet on blockchain integration.He's most excited about the market that will come when firms start posting their data to decentralized marketplaces, selling it via secure, live auctions he calls the "NASDAQ for data."Gobaud said:

"More advanced or technical users are really excited about the data marketplace because they are aware that getting data into blockchain ecosystem is really complicated."

Data generated on blockchain protocols is easy to verify because they are closed environments. But data from the real world can't be verified on a blockchain without help.


That's why Mobius is building a proof-of-stake oracle system, so that data streams with data from the real world can build up reputations as reliable sources over time. With the system, to put its data up for sale on the market, a company would have to prove it holds a certain amount of tokens.

If that marketplace catches on, the cost of staking should be more than paid for by revenue from selling data over time.


This could be anything from data about road conditions from a smart vehicle or local weather from a sensor on top of a commercial building.To reach the point where the decentralized web has a rich enough ecosystem to support these marketplaces, the team is also working to solve other small problems faced by developers on the way there.


For example, it built a universal login protocol, where a website can verify that a device holds a token to let its user log on to a service. Some sites might want to take this a step further and use tokens to integrate the level of access someone has to a site.


So, on a platform like Reddit, a user might only need one token, while a moderator might need a few tokens to log in with more advanced permissions.In the meantime, developers are already building dapps for Mobius' store, but it's small scale offerings so far, little video games or prediction games.


That's work at the experimental level, but Gobaud said he's encouraged by the fact that people already want to work with it. The websites on Geocities were crude, too, but they were a stepping stone to the web we know today.He concluded:

"It's like the early days of the internet."
