Geneva, Switzerland — September 16, 2026 — The Office of Justin Sun today announced the establishment of the Justin Sun Prize, a zero-trust, decentralized academic bounty mechanism based on a “problem list,” with breakthroughs in fundamental disciplines and machine formal verification as the criteria for awarding prizes, and a top prize of up to US$1 million for a single problem. The prize seeks to redefine scientific rewards in the AI era and accelerate fundamental scientific research through collaboration between humans and AI. The first list of Justin Sun Prize winners was also announced, recognizing solutions and formalized proofs involving 66 mathematical problems. The top prize, worth US$1 million, was awarded to the OpenAI research team in recognition of its solution and formalized proof for the Existence and Smoothness of the Three-Dimensional Navier–Stokes Equations problem. According to information published by OpenAI, the relevant proof was produced by its internal model, and the Lean formalization and verification were completed by GPT‑6 Astra. This problem concerns the Navier–Stokes equations, which describe the motion of fluids and are commonly abbreviated as the N–S equations. The equations were developed in the 19th century by French physicist Claude-Louis Navier, Irish-born British mathematician George Gabriel Stokes, and others, and have a history of approximately two hundred years. In 2000, the Clay Mathematics Institute listed the Navier–Stokes Existence and Smoothness problem as one of the seven Millennium Prize Problems and offered a US$1 million reward for its solution. The Justin Sun Prize does not use traditional nominations or credential thresholds as barriers to entry, nor does it operate on a four-year cycle or the rhythm of lifetime achievement. Instead, it ties the prize directly to mathematical problems and machine-verifiable formalized proofs. Anyone can receive the prize as long as they are the first to achieve a qualifying breakthrough. The vision of the Justin Sun Prize is to become the “Nobel Prize of the AI Era,” responding to the profound transformation of scientific research and incentives in the new era in a more decentralized, formalized, and machine-driven way. The repository of mathematical problems and formalized code will be maintained and publicly updated on an ongoing basis. Once a problem is listed, it is locked in: problems can be added only, never removed; awarded prize funds do not need to be returned under any circumstances. The current problem list already includes formal verification of the Poincaré Conjecture, the Riemann Hypothesis, Goldbach’s Conjecture, and a large number of unsolved problems proposed during the lifetime of the late mathematician and Wolf Prize laureate Paul Erdős. In addition to the prize, winners will also receive a certificate and a medal. The edge of the medal is inscribed with the Latin phrase “Quod probatur, solvitur,” meaning “Proved, then paid.” The Justin Sun Prize adheres to three core principles: openness, public benefit, and open source. It is open to all eligible contributors, with no restrictions based on nationality, institution, or identity, and makes no distinction between humans and AI; funds are used exclusively for prize awards and open initiatives and are not intended for profit; the problem list, confirmation standards, proofs, and verification materials are all made available to the public through GitHub, while prize disbursement records are recorded on-chain for permanent traceability and immutability. “An award named after a person is the least political thing in the world,” said Sun. “More importantly, it gives me an answer to myself—my wealth is rooted in mathematics. It came from mathematics, and it will return to mathematics.” According to public records, Sun has donated more than US$45 million across technology, environmental protection, disaster relief, and other fields. The Justin Sun Prize will become a central focus of Sun’s philanthropic efforts, continuing to support breakthroughs in fundamental science through an open and verifiable model. The prize will be paid out in either USDT on TRON (TRC-20) or USDC on Ethereum (ERC-20) based on the recipient’s choice. For more information, please visit www.hejustinsun.com/prize. About the Office of Justin Sun The Office of Justin Sun supports Justin Sun’s global business, philanthropic and public initiatives across technology, blockchain, artificial intelligence, scientific research, investment, art and space exploration.

In August 2025, he flew aboard Blue Origin’s NS-34 mission, becoming the 712th person in history to travel to space. His broader interests span technology, investment, philanthropy, art, gaming, and space exploration. Office of Justin Sun Contact: info@hejustinsun.com About Justin Sun Prize The Justin Sun Prize is an academic initiative established by Justin Sun to support advances in mathematics, formal verification, and AI-assisted scientific discovery. The prize is decentralized and built around the principle that mathematical work should be judged by the strength, rigor, and verifiability of the proof itself, not the prestige or reputation of those submitting it. Justin Sun established the prize in his own name as a long-term commitment to return wealth created through mathematics and technology back to mathematics itself. Its legacy is intended to be defined by the body of work it recognizes and the laureates whose discoveries stand the test of time. The prize links clearly defined mathematical challenges to machine-verifiable proof. Its guiding principles are openness, public benefit and open-source access.

Mutsamudu, Comoros, September 16, 2026 – MEXC, a pioneer in 0-fee digital asset trading, has released its July–August 2026 security report. The report shows that MEXC successfully intercepted all 215 reports involving risk-related funds during the period, covering approximately 38.66 million USDT. The total balance of the Futures Insurance Fund rose to 792 million USDT. Meanwhile, the reserve ratios for BTC, ETH, USDT, and USDC all remained above 100%. In July and August 2026, the crypto industry recorded 184 security incidents, with reported losses totaling approximately $535 million. Phishing and fraud incidents, together with endpoint and supply-chain security incidents, accounted for approximately 48% of the total. At the same time, a growing number of attackers are using AI to auto-generate phishing content and help write malware, increasing the efficiency of their attacks. As attack methods become more diverse, promptly identifying and intercepting risk-related funds and strengthening cross-platform investigation have become increasingly important to reducing user losses. All 215 Reports of Risk-Related Funds Successfully Intercepted, Covering 38.66 Million USDT In July and August, MEXC assisted with 215 reports involving externally stolen or fraud-related funds flowing into the platform. All 215 cases were successfully intercepted, covering 38,655,490 USDT. Of these cases, 42 involved assistance with judicial freezes. Compared with the previous reporting period, the number of successfully intercepted cases increased by approximately 2,971%, while the value of intercepted funds increased by approximately 12,646%. In tracking and handling risk-related funds, MEXC shared suspicious addresses with major industry participants, assisted in identifying fund flows, and supported verification and freezing procedures under established joint-investigation and law-enforcement cooperation procedures. Over 20,000 Risk-Related Accounts Identified and Restricted, With More Than 600,000 USDT in Misdirected Assets Returned In account risk identification, MEXC identified and restricted 20,752 accounts associated with risk-related activities during the period, an increase of 118.03% from the previous reporting period. The platform identified 5,288 risk groups, up 20.35%. By region of origin, these groups were concentrated primarily in the Commonwealth of Independent States (1,803), Nigeria (1,099), and Indonesia (976). For user asset recovery, MEXC manually processed 818 applications for the return of misdirected assets, returning the equivalent of 602,225 USDT, an increase of 75.31% from the previous reporting period. Futures Insurance Fund Reaches 792 Million USDT, Strengthening Protection Against Negative Balance Risk As of September 1, 2026, the total balance of the MEXC Futures Insurance Fund reached 791,696,422 USDT, an increase of 5.44% from the previous reporting period. The Futures Insurance Fund covers negative balances that may arise during liquidation, providing a risk buffer during extreme market conditions and helping reduce the likelihood of auto-deleveraging (ADL). When a liquidated position is closed at a price better than the bankruptcy price, the remaining funds are credited to the fund. Users can view the real-time balance on the MEXC Proof of Trust page. Reserve Ratios for Four Major Assets Remain Above 100%, With BTC at Approximately 288% According to the proof of reserves disclosed for this period, MEXC maintained reserve ratios above 100% for four major assets, as follows: Bitcoin (BTC): reserve ratio of approximately 288%, with total wallet assets of 12,312.75 BTC against 4,282.20 BTC in user assets; Ethereum (ETH): reserve ratio of approximately 113%, with total wallet assets of 66,227.79 ETH; USDT: reserve ratio of approximately 115%, with total wallet assets of approximately 1.940 billion USDT; USDC: reserve ratio of approximately 114%, with total wallet assets of approximately 194.85 million USDC. The on-chain addresses corresponding to these reserve assets have been disclosed, allowing users to verify through the Merkle Tree whether their individual account balances were included in this proof of reserves. As an additional layer of user asset protection, the MEXC Guardian Fund maintains a dual-reserve structure of USDT and BTC: USDT provides immediate liquidity support, while BTC serves as a long-term reserve asset across market cycles. MEXC plans to expand the fund from $100 million to $500 million, continuing to strengthen user asset protection. The relevant holding addresses are listed below: Guardian Fund Wallet Addresses: USDT: 0x469AfE803C54A36674C55231489Cf4b61da8c1bC BTC: 1MDVjZdX8QD212pT8Z8EMP7DuFQHKqN3mx MEXC CEO Vugar Usi said, “Trust is the true reserve currency of this industry. Protecting user assets means moving decisively the moment risk emerges, while giving users something they can verify for themselves, not just our word for it. We will continue to strengthen our ability to identify and intercept risk-related funds, deepen cooperation across platforms and with law enforcement, and help affected users recover their losses wherever possible. Our bi-monthly security reports are part of that commitment, allowing our security performance to be measured and tracked over time.” About MEXC Founded in 2018, MEXC is a leading global multi-asset trading platform built as your 0-fee gateway to infinite opportunities.

Alright, let's talk about what's happening on USELESS/USDC right now on Coinbase Advanced Spot. The European session gave us a setup that's worth breaking down — extreme order book imbalance, a volume spike, and price sitting above the key moving averages. That combo doesn't show up often. Exchange Coinbase Advanced Spot Entry Zone: 0.20590000 Target: 0.21413600 (+4.00%) Session: European (07:00–12:00 UTC) Trend Structure — Clean Bullish Backdrop Price is trading above both the 200 EMA and 200 SMA on the daily. That's the bull/bear line for me. When we're above both, I'm looking for longs, not shorts. Simple as that. Condition Status Price > 200 EMA ✅ Price > 200 SMA ✅ Order Book Imbalance: +80.8% Volume Spike: ≥2.0x ✅ Order Book — Buyers Are Dominating +80.8% buy-side imbalance. That's about as extreme as it gets. Demand is absolutely crushing displayed sell liquidity right now. What I'm seeing: Big players accumulating aggressively Sellers getting absorbed fast Price likely has to move up to find real sell pressure This kind of reading doesn't sit around for long. Either price moves, or the imbalance fades. I'm betting on the former here. When whales load up, they don't just market buy. They use iceberg orders, let volume dry up, then push. All of that is showing up in this structure. 24h Change: -0.4% 24h Volume: 48.7M Here's the interesting part price hasn't moved yet. Down 0.4% on the day with an 80% buy imbalance? That's hidden accumulation. Classic pre-breakout behavior. What I'm Watching Holding above 0.20590000 if buyers defend this, we're good Volume expanding toward 0.214136 real breakouts need participation Imbalance staying elevated if it drops, momentum stalls Reaction at target I'll consider scaling out if volume keeps pushing

Mutsamudu, Comoros, September 15, 2026 – MEXC, a pioneer in 0-fee digital asset trading, has released its September 2026 Proof of Reserves (PoR) report, audited by Hacken, confirming that user assets remain fully backed across all major reserve assets. The BTC reserve ratio increased to 297%, up from 288% in August. MEXC continues to disclose reserve data on a monthly basis, aiming to enhance transparency and safeguard the security of user funds. According to the audited report, dated as of the September 10, 2026 snapshot, reserve ratios for all disclosed assets are as follows: BTC: 297%. Reserves of 12,202.13 BTC cover 4,106.57 BTC in user holdings. USDT: 119%. Reserves of 1,818,202,910.24 USDT cover 1,526,526,878.38 USDT in user holdings. USDC: 111%. Reserves of 299,925,929.77 USDC cover 269,894,125.25 USDC in user holdings. ETH: 111%. Reserves of 58,917.60 ETH cover 53,243.98 ETH in user holdings. MEXC verifies its reserves through Merkle Tree technology, allowing individual users to confirm their balances are included in the total reserve calculation without exposing other users’ data. For this month’s audit, Hacken conducted a comprehensive evaluation of MEXC’s reserves, covering Proof of Liabilities, Proof of Ownership, Reserves Calculation, and a PoR Assessment. Hacken confirmed that MEXC’s reserves exceed a 1:1 ratio across all in-scope assets, fully covering user liabilities. “Protecting user assets and earning their trust are fundamental responsibilities, not optional commitments,” said Vugar Usi, CEO of MEXC. “In an industry where confidence has been tested time and again, transparency must be demonstrated through actions that users can independently verify. That is why we publish verifiable Proof of Reserves every month, giving users the ability to validate their asset data at any time rather than simply relying on our assurances. Our commitment is to continue raising the standard for transparency, accountability, and asset protection, and to build the kind of trust that is earned consistently over time.” To further protect user assets, MEXC maintains the Futures Insurance Fund, which absorbs losses from liquidations triggered by extreme market conditions. The fund held a balance of approximately 798 million USDT as of press time. MEXC also operates The Guardian Fund, a dual-reserve structure combining USDT and BTC holdings that offers full compensation coverage for platform-related issues. It held a balance of $101 million as of press time and plans to expand to $500 million within two years.

USDC's milestone highlights its pivotal role in DeFi, but Circle's revenue reliance on interest rates poses financial stability risks.

Hello Traders, Nice to see you all. If you follow me, you can always receive new updates quickly. Have a great day today. ------------------------------------- https://www.tradingview.com/x/qlYlpeAd/ ETH's volatility period is expected to continue until September 15. Since the current flow of funds is moving sideways with a bearish bias, it may be difficult for the price to sustain an upward trend. https://www.tradingview.com/x/X9QUS5RA/ https://www.tradingview.com/x/pomGQ6uw/ For the flow of funds to improve, I believe the upward gap expansion in USDT and USDC should continue. Therefore, it is important to monitor whether ETH can find support around 2510.94 and move higher. If the price rises, the key point will be whether 2887.66 can act as support. - Thank you for reading to the end. I wish you successful trading.
