Crypto Market Overview
BTC (+0.16% | Current Price: $116,008.39)
Recently, the price of BTC has generally fluctuated between $115,000 and $116,600. While the price has repeatedly found support near $115,400, it has encountered strong resistance near $116,600 and has been unable to break through. On September 12th, BTC ETFs saw a net inflow of $642 million, with BlackRock IBIT saw a net inflow of $264 million and Fidelity FBTC receiving $315 million.
ETH (-1.20% | Current Price: $4,609.43)
The recent ETH market has shown a pattern of initially rising strongly, followed by a volatile decline. After reaching a peak near $4,766, the price encountered resistance and fell back, currently trading around $4,620. On September 12th, ETH ETFs saw a net inflow of $405 million, with BlackRock ETHA receiving $165 million and Fidelity FETH receiving $168 million.
Altcoins
The overall cryptocurrency market capitalization stands at around $4.06 trillion. Altcoins showed some recovery, but many are still nursing losses from mid-August to early September. Solana (SOL) is showing momentum. The Altcoin Season Index is at 70%, nearing the 75% trigger for "altcoin season". Most major altcoins saw slight declines, with market sentiment remaining neutral. The Fear & Greed Index (FGI) was at 51, within the normal range, indicating that market sentiment has eased somewhat relative to previous panic levels.
Macro Data
The broader market is influenced by expectations of a US Federal Reserve rate cut later this week, which is driving speculative demand in risk assets like cryptocurrencies. Lower rates tend to inject liquidity into the market. However, long-term Treasury yields might remain elevated due to inflation concerns, potentially dampening some of the bullish sentiment. The US dollar traded mixed, and the US University of Michigan Sentiment survey showed a decline in September. In other news, Fitch Ratings downgraded France's credit rating, citing political turmoil and rising debt.
On September 12, the S&P 500 fell 0.05% to 6,584.29; the Dow Jones Industrial Average fell 0.59% to 45,834.22; and the Nasdaq Composite Index rose 0.44% to 22,141.10. As of 10:30 AM (UTC+8) on September 15, the spot gold price was currently at $3,642 per ounce, down 0.02% in the past 24 hours.
Trending Tokens
IO io.net (+8.88%, Circulating Market Cap: $143.96 Million)
IO is trading at $0.7042, up approximately 8.88% in the past 24 hours. io.net is a leading decentralized cloud provider that deploys and manages on demand GPU clusters from geographically distributed data centers. Thousands of GPUs are available through the io.net network, designed for low latency, high-performance use cases such as AI/ML operations and cloud gaming. IO will unlock 13.29M tokens (~$7M) on September 11, representing 6.24% of its circulating supply. While unlocks often trigger fears of dilution, similar unlocks in July 2025 saw prices rise as markets priced in strategic allocations (e.g., developer incentives). IO broke above its 7-day SMA ($0.63) and 23.6% Fibonacci retracement ($0.64), supported by: MACD histogram: Turned positive (+0.0147), signaling bullish momentum and RSI (14-day): 55.44 – neutral but rising, avoiding overbought territory. IO’s decentralized GPU network aligns with the AI infrastructure boom. Projects like Aethir and Bittensor saw 20–40% gains this week, lifting sentiment for DePIN tokens.

Ethereum Foundation Sets End-to-end Privacy Roadmap, With Private Writes, Reads and Proving
An Ethereum Foundation team has released a roadmap outlining current progress and future plans towards building comprehensive end-to-end privacy into the world's second-largest blockchain.
The Ethereum Foundation's Privacy & Scaling Explorations team has rebranded itself to Privacy Stewards of Ethereum (PSE), changing its focus from pursuing speculative exploration of new tech to solving concrete problems and improving ecosystem outcomes. The new PSE team released a
roadmap on Friday, Sept. 12, outlining its current work and future goals for privacy on Ethereum, compiled by team member Sam Richards.
"Ethereum is on the path to becoming the settlement layer for the world, but without strong privacy, it risks becoming the backbone of global surveillance rather than global freedom," Richards' roadmap states. "If Ethereum fails to build privacy, it fails to protect the people who rely on it."
The roadmap centers around three areas of focus: private writes, making private onchain actions as cheap and seamless as public ones, private reads, enabling reading from the blockchain without revealing identity or intent, and private proving, making proof generation and verification fast, private, and accessible.
Polkadot DAO Passes Proposal to Cap Total DOT Supply at 2.1 Billion
Polkadot DAO (Decentralized Autonomous Organization) Referendum #1,710 passed with a resounding 81% approval rate, capping the total supply of DOT tokens at 2.1 billion. This marks the end of Polkadot's current uncapped annual issuance of 120 million DOTs. Under the new proposal, future DOT issuance will gradually decrease every two years, significantly slowing the growth of the token supply and fostering a greater sense of scarcity in the market.
The passage of this proposal marks the Polkadot economic model's entry into a "fixed supply + declining issuance" phase, with significant implications for both investors and ecosystem participants. On the one hand, the supply cap and gradual issuance reduction mechanism are likely to enhance DOT's scarcity value and strengthen the confidence of long-term holders. On the other hand, it also reflects the growing maturity of Polkadot's ecosystem governance and the community's increasing focus on inflation control and token economic sustainability. In the short term, the market may form positive expectations for DOT, but at the same time, it is important to consider the impact of gradual issuance reductions on the balance between network incentives and ecosystem expansion.
Tether Launches USAT, First Fully Regulated Digital Dollar in the U.S.
The giant of the most popular stablecoin in the world (USDT), Tether, is making a historic move to transform the U.S. crypto economy. As the company announced USAT, a U.S. regulated stablecoin, the company targets strengthening U.S. dollar supremacy in the age of blockchain, now with American leadership and regulation.
The introduction of USAT by Tether is timely considering the fact that the regulators in the United States started formalizing the regulations of stablecoins via the GENIUS Act that is signed in July 2025. The new law requires all stablecoin issuers to work under stringent compliance with complete reserve support through liquid asset and monthly reserve reports. USAT will be:
In full compliance with the GENIUS Act.

The Bitcoin Hashrate Hit 1 Zetahash Per Second
The Bitcoin hashrate is at an all-time high. A zetahash is a trillion exahashes, or one sextillion hashes, and this figure represents the total computational muscle powering Bitcoin’s Proof-of-Work consensus system. Miners deploy purpose-built computers to compete for new blocks, rapidly running cryptographic “nonce” guesses until one solution fits.
Hashrate is the lifeblood of Bitcoin security, and this brute-force lottery drives network trust: the higher the hashrate, the harder it is for any attacker to rewrite Bitcoin’s ledger. The recent settling above 1 ZH/s means that every second, miners perform more calculations than grains of sand on earth, or more than the stars in our galaxy; a mind-boggling testament to decentralized security. Miners compete to find a valid hash for the next block. Each hash is an attempt to meet network difficulty requirements, and success wins a Bitcoin reward.
At over 1 ZH/s, the difficulty rises in tandem, mandating ever-greater efficiency and innovation in mining hardware. A higher Bitcoin hashrate means stronger protection from double-spending and 51% attacks, and as more energy and hardware secure the chain, Bitcoin becomes increasingly tamper-proof and globally trusted.
