South Korean exchanges Upbit and Bithumb have suspended deposits for Synthetix (SNX) tokens after it was flagged by the Digital Asset Exchange Alliance (DAXA) for potential risks.DAXA, the self-regulatory organization establishing industry standards for South Korean exchanges, designated SNX as a cautionary item. Assets receiving this designation typically undergo rigorous evaluations to determine whether trading can continue or if delisting is necessary.Exchanges may take action, such as adding a warning tag to the asset and urging investors to take caution when engaging with it. Trading platforms can also perform additional measures, like blocking deposits or suspending trading support temporarily. Upbit and Bithumb block SNX depositsIn response to the designation, the biggest exchanges in South Korea said they are blocking deposits for SNX tokens on their platforms. Upbit announced that it had added a trading caution ticker and suspended token deposits. The exchange said it had been monitoring the developments related to the Synthetix USD (sUSD) depegging. It added that this event may damage investors through potential volatility, as SNX is used as collateral for sUSD. The exchange added that it had determined a lack of use cases for the asset, which may cause investors to suffer losses. Upbit said it would conduct a comprehensive review to decide whether to delist the asset or resume normal operations for the token. Bithumb has also blocked deposits for SNX and added a cautionary tag for the token. However, the exchange said this decision could be overturned depending on internal circumstances. If the reason for the designation is resolved, Bithumb said it would lift the restrictions. Korbit and Coinone also published investor alerts to caution traders. The two exchanges added cautionary tags to SNX tokens to alert investors who may want to trade the token. Cointelegraph reached out to Synthetix for comment but did not get a response by publication.

With the stablecoin being collateralized by the project’s native asset, Cork Protocol co-founder Rob Schmitt compared the token to Terra USD (UST), which collapsed in 2022. However, Schmitt said that sUSD has a “more manageable” debt system. On April 18, the stablecoin dipped further to $0.68, with SNX falling by 26% in a 30-day period. A Synthetix spokesperson told Cointelegraph that their team has short, medium and long-term plans to mitigate the risks. On April 21, Synthetix founder Kain Warwick threatened SNX stakers with “the stick” if they didn’t take up a newly launched staking mechanism to fix the sUSD depeg. The executive said they may put extra pressure on stakers if they don’t see enough momentum on the newly implemented mechanism. Since the warning, sUSD prices increased by 27%. On April 24, the stablecoin briefly reached $0.87. However, the token has still failed to recover its dollar peg.

The host of The Wolf Of All Streets podcast, Scott Melker, says he’s received word that his face and name are being impersonated by scammers, with at least one victim duped out of $4 million. On April 23, the crypto investor said, “I’m sick,” reporting that he’d been contacted by a private investigator revealing that a client of his was scammed for $4 million by a Nigerian group using his name and face as bait. “They’ve apparently scammed a number of people,” Melker said, adding, “They sent him a fake driver’s license to prove it was me,” and used his X avatar as the photo.The scammers used AI to generate the fake ID and used a fake but convincing-looking email account. “They do zoom calls with AI,” which are “apparently sophisticated,” said Melker, who added that the scammers have also spoofed accounts of his wife and kids to support identity confirmation. Fake driver's license used by scammers. Source: Scott Melker Technical analysts “TheChartGuys” reported something similar, with a person getting scammed for $5,000 after the scammers replicated their voice using AI deepfakes. Fake ID is easy to spot, says traderCrypto adviser and trader “Nebraskan Gooner” said a quick Google search easily reveals that the ID is fake. He pointed out that there were a few subtle discrepancies in the address and date formats. He said that it it sucks that these scammers are getting so sophisticated, but was “surprised how badly this was with how sophisticated of an operation these seems to be.” Cointelegraph reached out to Melker for further comments but did not receive an immediate response.

A little-known VOXEL trading pair on cryptocurrency exchange Bitget suddenly clocked over $12 billion in volume on April 20, dwarfing the metrics of the same contract on Binance.The activity centered on VOXEL/USDT perpetual futures, where traders reported instant order fills — an anomaly many described as a bug that allowed savvy traders to rack up outsized profits by exploiting unusual price behavior.The atypical metrics drew Bitget’s attention. In the fallout of its early investigation, the exchange suspended accounts suspected of market manipulation and rolled back irregular trades that occurred throughout the day. Traders who copped losses during that period were offered compensation.Bitget’s response and remediation plan may have prevented lasting investor damage, but the episode is the latest in a series of cases that raise questions about how exchanges handle market makers, internal systems and user safeguards. While Bitget promotes an open API and regularly touts its global market maker program, it has yet to disclose who was behind the April 20 activity or what technical factors led to it.The lack of incident-level detail has fueled speculations comparable to similar breakdowns on Binance — the world’s largest exchange by trading volume — that included the sudden price crashes of cryptocurrencies GoPlus (GPS) and MyShell (SHELL) in March. Binance kicked out an unnamed market maker it found responsible for manipulation, but the lack of disclosure added fuel to the crypto industry’s infamous rumor mongering.Bitget’s VOXEL/USDT perpetual futures volume exceeded that of all other top 10 markets combined on April 20. Source: Thành CryptoTraders VOXEL market maker bug, Bitget disagreesCrypto market participants pointed to rapid price fluctuations and what multiple Mandarin-language X accounts described as a bug in a “market maker” bot as the cause of VOXEL’s excessive volume.Traders claimed that VOXEL’s price flickered between several ranges, such as $0.125 and $0.138. Orders placed between those bands filled instantly due to the suspected bug, X user Dylan said, sharing screenshots and videos of profitable accounts. Perpetual futures contracts are typically matched through an order book, with each trade requiring a counterparty. But in this case, trades appeared to execute automatically and without delay.A machine-translated post shares how one trader profits hundreds of thousands of dollars with just $100 USDT in starting capital. Source: 0xDy_ethTraders who spotted the suspected bug early used high-leverage bets to boost their profits, X user Qingshui said, calling the strategy a “zero-cost exploit.” Like Dylan, Qingshui attributed the issue to a market maker bot misfiring and questioned why traders were blocked from accessing profits if the problem originated from Bitget’s side.Related: How Mantra’s OM token collapsed in 24 hours of chaosA third user, Hebi555, pointed the finger at Bitget’s market-making team for its poor performance. Xie Jiayin, Bitget’s head of Asia, clapped back, stating that the exchange works with over 1,000 market makers and institutional clients. He added that Bitget’s API is open to the public and emphasized that specific market maker identities could not be disclosed due to confidentiality agreements.In an April 20 response to Cointelegraph, Bitget CEO Gracy Chen said that suspicious trades were between individual market participants, not the platform. Replying to Cointelegraph’s follow-up inquiry on April 21, Chen neither confirmed nor denied whether a market maker bot was involved, only reiterating that the trading was “between users.”“We are conducting a thorough review, and once the rollback is completed, trading and account restrictions will be lifted as appropriate. Bitget’s security infrastructure is designed to catch irregularities like this in real time — as it did in this case,” Chen said.Bitget’s VOXEL anomaly adds to crypto’s market manipulation mysteryConcerns over market manipulation in the cryptocurrency industry have been intensifying. In early March, the prices of two tokens, GPS and SHELL, crashed in tandem with their Binance listings. The exchange’s investigation found that the two tokens employed the same unnamed market maker. Binance banished the dubious trading firm from its platform and confiscated its proceeds to help fund compensation efforts for GPS and SHELL traders. Without a suspect to blame, social media users began pointing fingers at several market makers and trading firms. Those named denied any involvement.GSR was among the most frequently accused firms, but denied being the market maker removed by Binance. Source: GSRBinance then kicked out another unnamed market maker, this time for trading activities related to the Movement (MOVE) token. The MOVE token’s market maker on Binance was found to have associations with the market maker for GPS and SHELL.Related: Market maker deals are quietly killing crypto projectsA recent Cointelegraph report found that market makers are employing a loan-based model that is killing off small- and medium-cap projects. The loan model gives market makers access to a project’s tokens in exchange for liquidity provision. But instead, what often happens is that market makers dump the loaned tokens on the open market just to buy them back at a cheaper price, leaving the projects with damaged price charts.VOXEL was on Bitget, but exploits aren’t limited to CEXsBoth Bitget and Binance’s cases show that even the largest centralized exchanges (CEXs) aren’t immune to market manipulation or traders exploiting platforms for profits.But a recent case on decentralized exchange (DEX) Hyperliquid shows the issue isn’t confined to CEXs. In late March, a whale allegedly exploited the liquidation parameters on Hyperliquid, resulting in the delisting of the platform’s JELLY perpetual futures product. Hyperliquid then announced a compensation plan for affected users, similar to how Bitget responded to its own VOXEL drama.X user spotlights double standards in how exchanges respond to bugs. Source: Dotyyds1234Ironically, Bitget’s Chen had some strong words against Hyperliquid at the time, raising concerns about the network’s centralization. She compared the DEX to FTX, once a billion-dollar trading firm whose founder is now serving a 25-year prison sentence for multiple counts of fraud.“The way it handled the JELLY incident was immature, unethical, and unprofessional, triggering user losses and casting serious doubts over its integrity. Despite presenting itself as an innovative decentralized exchange with a bold vision, Hyperliquid operates more like an offshore CEX with no [Know-Your-Customer/Anti-Money Laundering], enabling illicit flows and bad actors,” she said.Bitget’s VOXEL episode may have been contained, and Hyperliquid’s users may be compensated, but the broader pattern is harder to ignore for traders. As platforms scramble to maintain trust, the industry’s vulnerability isn’t just the bugs or exploits, but the silence that follows them.Magazine: Uni students crypto ‘grooming’ scandal, 67K scammed by fake women: Asia Express
