Crypto Might Have an Insider Trading Problem

Public data suggests that several anonymous crypto investors profited from inside knowledge of when tokens would be listed on exchanges.

Over six days last August, one crypto wallet amassed a stake of $360,000 worth of Gnosis coins, a token tied to an effort to build blockchain-based prediction markets. On the seventh day, Binance—the world’s largest cryptocurrency exchange by volume—said in a blog post that it would list Gnosis, allowing it to be traded among its users.

Token listings add both liquidity and a stamp of legitimacy to the token, and often provide a boost to a token’s trading price. The price of Gnosis rose sharply, from around $300 to $410 within an hour. The value of Gnosis traded that day surged to more than seven times its seven-day average.

Four minutes after Binance’s announcement, the wallet began selling down its stake, liquidating it entirely in just over four hours for slightly more than $500,000—netting a profit of about $140,000 and a return of roughly 40%, according to an analysis performed by Argus Inc., a firm that offers companies software to manage employee trading. The same wallet demonstrated similar patterns of buying tokens before their listings and selling quickly after with at least three other tokens.

The crypto ecosystem is increasingly grappling with headaches that the world of traditional finance tackled decades ago. The collapse of a so-called stablecoin from its dollar peg earlier this month stemmed from crypto’s version of a bank run. How cryptocurrency exchanges prevent market-sensitive information from leaking has also become a growing topic of concern. The focus comes as regulators are raising questions about the market’s fairness for retail users, many of whom just booked major losses on steep declines in crypto assets.

The wallet buying Gnosis was among 46 that Argus found that purchased a combined $17.3 million worth of tokens that were listed shortly after on Coinbase, Binance and FTX. The wallets’ owners can’t be determined through the public blockchain.

Profits from sales of the tokens that were visible on the blockchain totalled more than $1.7 million. The true profits from the trades is likely significantly higher, however, as several chunks of the stakes were moved from the wallets into exchanges rather than traded directly for stablecoins or other currencies, Argus said.

Argus focused only on wallets that exhibited repeated patterns of buying tokens in the run-up to a listing announcement and selling soon after. The analysis flagged trading activity from February 2021 through April of this year. The data was reviewed by The Wall Street Journal.

Coinbase, Binance and FTX each said they had compliance policies prohibiting employees from trading on privileged information. The latter two said they reviewed the analysis and determined that the trading activity in Argus’s report didn’t violate their policies. Binance’s spokesperson also said none of the wallet addresses were linked to its employees.

Coinbase said it conducts similar analyses as part of its attempts to ensure fairness. Coinbase executives have posted a series of blogs touching on the issue of front running.

“There is always the possibility that someone inside Coinbase could, wittingly or unwittingly, leak information to outsiders engaging in illegal activity,” Coinbase Chief Executive Brian Armstrong wrote last month. The exchange, he said, investigates employees that appear linked to front running and terminates them if they are found to have aided such trades.

Paul Grewal, Coinbase’s chief legal officer, followed up with a blog post Thursday. The company has seen information about listings leak before announcements through traders detecting digital evidence of exchanges testing a token before a public announcement, he said. Coinbase has taken steps to mitigate that in addition to its efforts to prevent employee insider trading, he said.

Wallets like these have caused debate in the crypto community over whether targeted buying of specific tokens ahead of listings on exchanges points to insider trading. The crypto markets are largely unregulated. In recent years, regulators have looked more closely at the market’s fairness for individual investors. The largest cryptocurrency bitcoin has fallen 24% in May, causing steep losses for individual investors across the market.

Insider trading laws bar investors from trading stocks or commodities on material nonpublic information, such as knowledge of a coming listing or merger offer.

Some lawyers say that existing criminal statutes and other regulations could be used to go after those trading cryptocurrencies with private information. But others in the cryptocurrency industry say a lack of case precedent specific to crypto insider trading has created uncertainty over whether and how regulators might seek to tackle it in the future.

Argus CEO Owen Rapaport said that internal compliance policies in crypto can be undercut by a lack of clear regulatory guidelines, the libertarian ethos of many who work in the space and the lack of institutionalized norms against insider trading in crypto compared with those in traditional finance.

“Firms have real challenges with making sure the code of ethics against insider trading—which almost every firm has—is actually followed rather than being an inert piece of paper,” Mr. Rapaport said.

Securities and Exchange Commission Chairman Gary Gensler said Monday that he saw similarities between the influx of individual investors into crypto markets and the stock boom of the 1920s that presaged the Great Depression, which led to the creation of the SEC and its mandate to protect investors.“The retail public had gotten deeply into the markets in the 1920s and we saw how that came out,” Mr. Gensler said. “Don’t let somebody say ‘Well, we don’t need to protect against fraud and manipulation.’ That’s where you lose trust in markets.”

Spokespeople for the exchanges said that they have policies to ensure that their employees can’t trade off of sensitive information.

A Binance spokeswoman said that employees have a 90-day hold on any investments they make and that leaders in the company are mandated to report any trading activity on a quarterly basis.

“There is a longstanding process in place, including internal systems, that our security team follows to investigate and hold those accountable that have engaged in this type of behaviour, immediate termination being minimal repercussion,” she said.

FTX CEO Sam Bankman-Fried said in an email that the company explicitly bans employees from trading on or sharing information related to coming token listings and has a policy in place to prevent that. The trading highlighted in Argus’s analysis didn’t result from any substantive violations of company policy, Mr. Bankman-Fried said.

Wedding planner Sterling Boulet has some advice for brides-to-be regarding lab-grown diamonds, which cost a fraction of the natural ones.

“If you’re trying to get your man to propose, they’ll propose faster if you offer this as an option,” says Boulet, of Raleigh, N.C. Recently, she adds, a friend’s fiancé “thanked me the next three times I saw him” for telling him about the cheaper lab-made option.

Man-made diamonds are catching on, despite some lingering stigma. This year was the first time that sales of lab-made and natural mined loose diamonds, primarily used as center stones in engagement rings, were split evenly, according to data from Tenoris, a jewellery and diamond trend-analytics company.

The rise of lab-made stones, however, is bringing up quirks alongside the perks. Now that blingier engagement rings—above two or three carats—are more affordable, more people are dealing with the peculiarities of wearing rather large rocks.

Esther Hare, a 5-foot-11-inch former triathlete, sought out a 4.5-carat lab-made oval-shaped diamond to fit her larger hands as a part of her vow renewal in Hawaii last year. It was a far cry from the half-carat ring her husband proposed with more than 25 years ago and the 1.5-carat upgrade they purchased 10 years ago. Hare, 50, who lives in San Jose, Calif., and works in high tech, chose a $40,000 lab-made diamond because “it’s nuts” to have to spend $100,000 on a natural stone. “It had to be big—that was my vision,” she says.

But the size of the ring has made it less practical at times. She doesn’t wear it for athletic training and swaps in her wedding band instead. And she is careful to leave it at home when traveling. “A lot of times I won’t take it on vacation because it’s just a monster,” she says.

The average retail price for a one-carat lab-made loose diamond decreased to $1,426 this year from $3,039 in 2020, according to the Tenoris data. Similar-sized loose natural diamonds cost $5,426 this year, compared with $4,943 in 2020.

Lab-made diamonds have essentially the same chemical makeup as natural ones, and look the same, unless viewed through sophisticated equipment that gauges the characteristics of emitted light.

At Ritani, an online jewellery retailer, lab-made diamond sales make up about 70% of the diamonds sold, up from roughly 30% two years ago, says Juliet Gomes, head of customer service at the company, based in White Plains, N.Y.

Ritani sometimes records videos of the lab-diamonds pinging when exposed to a “diamond tester,” a tool that judges authenticity, to show customers that the man-made rocks behave the same as natural ones. “We definitely have some deep conversations with them,” Gomes says.

Not all gem dealers are rolling with these stones.

Philadelphia jeweller Steven Singer only stocks the natural stuff in his store and is planning a February campaign to give about 1,000 one-carat lab-made diamonds away free to prove they are “worthless.” Anyone can sign up online and get one in the mail; even shipping is free. “I’m not selling Frankensteins that were built in a lab,” Singer says.

Some brides are turned off by the larger bling now allowed by the lower prices.When her now-husband proposed with a two-carat lab-grown engagement ring, Tiffany Buchert, 40, was excited about the prospect of marriage—but not about the size of the diamond, which she says struck her as “costume jewellery-ish.”

“I said yes in the moment, of course, I didn’t want it to be weird,” says the physician assistant from West Chester, Pa.

But within weeks, she says, she fessed up, telling her fiancé: “I think I hate this ring.”

The couple returned it and then bought a one-carat natural diamond for more than double the price.

When Boulet, the wedding planner in Raleigh, got engaged herself, she was over the moon when her fiancé proposed with a 2.3 carat lab-made diamond ring. “It’s very shiny, we were almost worried it was too shiny and was going to look fake,” she says.

It doesn’t, which presents another issue—looking like someone who really shelled out for jewellery. Boulet will occasionally volunteer that her diamond ring came from a lab.

“I don’t want people to think I’m putting on airs, or trying to be flashier than I am,” she says.

For Daniel Teoh, a 36-year-old software engineer outside of Detroit, buying a cheaper lab-made diamond for his fiancée meant extra room in his $30,000 ring budget.

Instead of a bigger ring, he got her something they could both enjoy. During a walk while on an annual ski trip to South Lake Tahoe, Calif., Teoh popped the question and handed his now-wife a handmade wooden box that included a 2.5-carat lab-made diamond ring—and a car key.

She put on the ring, celebrated with both of their sisters and a friend, who was the unofficial photographer of the happy event, and then they drove back to the house. There, she saw a 1965 Mustang GT coupe in Wimbledon white with red stripes and a bow on top.

Looking back, Teoh says, it was still the diamond that made the big first impression.

“It wasn’t until like 15 minutes later she was like ‘so, what’s with this key?’” he adds.

Anonymous wallets buy up tokens right before they are listed and sell shortly afterward.

Couples find that lab-grown diamonds make it cheaper to get engaged or upgrade to a bigger ring. But there are rocky moments.
