MEXC Under Fire Again After Users Flag Premarket Scams

TheNewsCryptoPublished on 2025-12-20Last updated on 2025-12-20

Abstract

MEXC faces renewed criticism as users report fund losses and premarket trading issues. Analyst Gautamgg highlighted two recent cases where the exchange allegedly violated its own rules. In one instance, a buyer purchased tokens at $0.40, but when the listing price reached $1.30, the seller defaulted. Instead of refunding the buyer as per Rule 10, MEXC retained the collateral. Another user reported canceled trades and frozen USDT for over 10 days with unclear support responses. This controversy follows previous accusations in late October when MEXC was accused of freezing over $3 million in user funds without justification. The exchange's CSO later apologized and released the funds. MEXC has since published Proof of Reserves and claims to combat fraud, having blocked over 70,000 fraud attempts recently. However, trust concerns persist as crypto scams surge industry-wide, with TRM Labs reporting a 456% increase in AI-related scams and $2.47 billion lost in the first half of the year.

MEXC is catching heat again as users report lost funds and premarket trade issues. Analyst Gautamgg posted on X about two big problems in the last 20 days that break the exchange’s own rules. Traders say support gives confusing answers and settlements drag on or fail.

🚨 MEXC SCAM EXPOSED – PROOF ATTACHED

I’ve been trading on MEXC premarket for the last 10–11 months without issues.
But as more new users joined recently, @MEXC_Official has started doing shady stuff.

In the last 20 days, 2 serious cases happened – must read

One case had a buyer picking up RateX at $0.4 while the listing hit $1.3. The seller didn’t settle, but MEXC kept the collateral instead of handing it to the buyer, going against their Rule 10 on refunds for defaults. Another trade got canceled, and USDT sat stuck for over 10 days with no clear word from support.

Past Drama Lingers

This echoes late October when trader The WhiteWhale accused MEXC of freezing over $3 million without good reason, tied to profitable trades. ZachXBT looked into similar complaints, sparking big backlash.

CSO Cecilia Hsueh apologized publicly October 31, admitting communication mess-ups, and funds got released. Withdrawals spiked amid solvency whispers, but MEXC denied issues and pointed to over 100% reserves.

MEXC posted fresh Proof of Reserves November 3 showing full backing for USDT, USDC, Bitcoin, and Ethereum. They use Merkle Tree checks with mirrors on CoinMarketCap, CoinGecko, and DefiLlama.

From April to June they blocked over 70,000 fraud tries linked to 8,500 groups, cutting fraud by 12%.Crypto scams are exploding anyway.

TRM Labs says AI scams jumped 456% from May 2024 to April 2025, with $2.47 billion lost first half of the year. One guy recently dropped $50 million USDT on a copy-paste wallet trick.

MEXC says reserves are solid and they’re fighting fraud hard, but trust takes hits with these reports. Traders have to stay alert, keep an eye on the rules, and be ready for sudden account closures in such a fast changing market.

TON/GRAM price prediction – Telegram’s Gram wallet rollout lifts token: Can the rally continue?

Telegram founder Pavel Durov announced the rollout of a native, non-custodial Gram wallet across the messaging app, describing it as potentially the largest deployment of a non-custodial wallet in history. The move aims to bring instant, zero-fee crypto transactions to Telegram's over one billion users, integrating digital assets directly into the platform. The news triggered a more than 7% price increase for TON/GRAM, pushing the token to around $1.53. However, it remains below its May peak near $2.80, facing immediate resistance around $1.60. Analysts suggest a break above this level could improve sentiment toward $1.80, while a failure to hold gains might see a retest of support near $1.40.

How 40.8M staked ETH could strengthen Ethereum’s edge over Bitcoin

Ethereum is showing signs of strengthening against Bitcoin, driven by two key trends. First, significant whale accumulation is occurring, with large holders not just buying ETH but immediately staking 100% of it. This locks away supply, signaling long-term conviction. Ethereum's total staked ETH has reached a record 40.8 million, with a growing entry queue and 33.5% of supply now staked, further tightening liquid availability. Second, Ethereum's DeFi ecosystem is experiencing robust activity, with WETH whale transactions at a multi-year high and Total Value Locked (TVL) rising sharply. These converging factors—reduced supply from staking and increased on-chain demand—are translating into technical strength. The ETH/BTC ratio has broken above resistance and is approaching the 0.03 level, setting the stage for potential continued outperformance against Bitcoin.

Global Stock Market's Storm Center: South Korea's Stock Market De-leveraging Is Largely Complete

Storm's Eye: South Korean Market De-leveraging Nears Completion The recent sharp correction in South Korean equities, with the KOSPI index dropping 32% from its June high, has been a key trigger for global tech stock volatility. The core driver was not a fundamental shift but a forced de-leveraging process within the market's unique structure, which is now largely complete. Two main leverage channels amplified the sell-off: 1. **Leveraged ETFs:** Their size, proportionally four times larger than in the U.S., peaked near $50 billion. Their mandatory daily rebalancing mechanism created a vicious cycle of "price drop → forced selling → further drop." Approximately 75% of this excess has been unwound, shrinking to $26 billion, with regulatory curbs now blocking new inflows. 2. **Hedge Fund Leverage:** Using swaps to magnify exposure, hedge funds saw their net long positioning fall by over 50% from peak levels. The most intense phase of this institutional de-leveraging is over. In contrast, **retail margin debt** poses minimal systemic risk. At 0.5% of market cap, it is far lower than in the U.S. or China, lacks automatic triggers, and is concentrated in smaller stocks. The conclusion: the high-leverage structures most prone to "chain-reaction selling" have been substantially cleared. The market is transitioning from a liquidity-driven crash to one priced more on fundamentals. The article argues that the AI trend—centered on Korean memory chips—remains intact. This episode represents a painful but necessary clearing of crowded trades, not the end of the AI revolution. For investors, the key question is conviction in the long-term AI direction; if the trend is real, current volatility is a cost of entry, not a terminal risk.

92.9% of crypto tokens launched since 2024 trade below TGE price: CryptoRank

A recent analysis by CryptoRank reveals that 92.9% of cryptocurrency tokens launched since 2024 and with a market capitalization exceeding $100 million are now trading below their initial Token Generation Event (TGE) price. The study, examining 113 projects, found only eight—or 7.1%—remain profitable, with the median return across the dataset being a stark -95.7%. Top performers include Hyperliquid (HYPE), which gained 1,519%, followed by Ondo Finance (ONDO), EverValue Coin (EVA), and Midnight Network (NIGHT). The findings indicate a market that has become highly selective, with capital concentrating on a small number of projects demonstrating real utility, adoption, or ecosystem growth. This contrasts with previous cycles where new tokens often saw sustained rallies. Investors are now scrutinizing factors like tokenomics, circulating supply, and unlock schedules more closely. This trend may influence future token launches, prompting projects to prioritize sustainable distribution models and long-term growth over aggressive initial valuations, as high fully diluted valuations (FDVs) and large future token unlocks often lead to significant price pressure.

The Eternal Fragments of Money: Third-Party Payment Has No First Principle

"The Enduring Fragments of Money: Third-Party Payments Lack a First Principle" Stripe is reportedly attempting to acquire PayPal, marking a significant shift reminiscent of PayPal's merger with the original X.com 30 years ago. The article analyzes Stripe's strategic challenges and the broader payments industry landscape. Despite its initial success with a developer-friendly API model, Stripe missed its optimal IPO window during the pandemic and has since seen its valuation decline. Its attempts to expand through acquisitions and new ventures, particularly in stablecoins (like its OUSD project) and Agent-focused payments (ACP/MPP protocols), have faced headwinds. The author argues that the payment industry remains highly fragmented and is ultimately an adjunct to the traditional banking system. This structure limits the potential for any single player, including Stripe, to achieve complete dominance. While stablecoins and the future rise of autonomous Agent economies present potential growth avenues, they are not yet mainstream and still require integration with the existing financial system. For now, Agent-based transactions are largely used for speculative "volume boosting" rather than substantive business applications. Stripe's current move to acquire PayPal is seen as an attempt to bolster its weak consumer-facing (C-side) business after its stablecoin-focused strategies faltered. Meanwhile, PayPal is described as structurally outdated, unable to revive itself through new products like Venmo or PYUSD. The future of payments may lie not in payments themselves but in value-added services like more efficient settlement networks. The author suggests that companies like Stripe and Circle, which are building their own blockchains (Tempo, Arc) and stablecoins, are positioning themselves to eventually profit from high-efficiency settlement systems. These new networks could potentially bypass some traditional banking layers. In conclusion, the article posits that third-party payment is a perpetually fragmented battlefield where scale alone cannot ensure victory. Players must find new models, focusing on efficiency to compete with the entrenched banking system. Stripe's acquisition of PayPal represents a bet on this uncertain future.
