BTCST Debuts as Bitcoin’s Leveraged Token on Binance Launchpool
Bitcoin Standard Hashrate Token (BTCST) is now live on Binance Launchpool, and Binance will then list BTCST in the innovation zone at 6:00 am (UTC) on Jan. 13, 2021.

BTCST sets off to solve the problem of a limited number of exit options by bringing exchange-grade liquidity to the Bitcoin mining industry, and in secondary trading, BTCST will perform as a leveraged Bitcoin token free from liquidation risk. BTCST will create an efficient market for Bitcoin’s mining power in ways similar to how Grayscale Bitcoin Trust creates institutional liquidity for Bitcoin.
Four Key Points About BTCST
1. Bitcoin’s leveraged token
BTCST secures dual profits for its holders when the market is on a bull run, due to BTCST’s attributes as Bitcoin’s leveraged token.
BTCST is collateralized by 0.1 TH/s of real-world Bitcoin mining power, which is historically proven to be positively correlated to the performance of the digital gold, and hence the value of BTCST climbs along with the current skyrocketing Bitcoin market. On top of that, BTCST stakers claim Bitcoin mining rewards on a daily basis. If a user started to mine Bitcoin with a WhatsMiner M21s (a classic hardware model of Bitcoin mining) in October 2020, by the time of publication, the value of Bitcoin mined would have risen by 200%; however, the price of the mining machine itself increased 400% during the same time frame.
Therefore, it is safe to call BTCST a leveraged token of Bitcoin.
2. Grayscale-like operations in the mining industry
2020 is the year of Grayscale, and BTCST may prolong the saga in the Bitcoin mining industry. Institutional liquidity injected by Grayscale sparked the bullish market, and BTCST will help release liquidity to the mining industry and enable the execution of liquidity premium in the secondary market.
BTCST creates an efficient market among Bitcoin miners. By trading BTCST, market participants can freely enter and exit Bitcoin mining exposure in any size, at any time, and with low costs. Even miners without mining power tokenized by BTCST can make use of the token to capture the profits or hedge against the risks of mining machine price fluctuation.
3. Enhanced cloud mining
Cloud mining is an imperfect solution to the lack of liquidity, and its reputation is clouded by frequent scams. The legitimate providers also fall short of full transparency.
BTCST is a cloud mining platform deployed on the Binance Smart Chain, with daily payouts executed by the dApp and all data traceable. Binance Pool, the world’s second-largest Bitcoin mining pool, functions as the auditor for BTCST and guarantees legitimacy and transparency.
4. DeFi of 2021
BTCST is a DeFi project without risks of impermanent loss. When a user un-stakes BTCST, the user is safeguarded by code to retrieve the same amount of BTCST along with the accrued Bitcoin mining rewards.
In addition, BTCST has passed the scrutiny of CertiK, one of the world’s leading blockchain security firms, scoring a 98 out of 100 in a security audit.

WindGroove Introduces AirFi One, a Ceiling-Based Home Entertainment System Combining Hi-Fi Sound, Light, and Airflow
The new premium smart technology brand reimagines the ceiling as an active layer for immersive audio, adaptive lighting, and everyday comfort.
Los Angeles, CA, United States, 7th Sep 2026 – WindGroove, a new premium smart technology brand focused on sensory living experiences, introduces AirFi One, a ceiling-based home entertainment system that integrates Hi-Fi audio, smart lighting, and airflow into one unified device. WindGroove seeks to reawaken the way people experience and perceive their living spaces by reimagining familiar parts of the home in unexpected ways. AirFi One is the first expression of this vision, transforming the often-overlooked ceiling into an active part of the home environment and creating a more immersive, comfortable, and emotionally responsive living experience.

For many households, a truly spatial ceiling audio experience has traditionally required complex renovation planning, reserved wiring, fixed installation points, and higher upfront investment. Such experiences have often been limited to mid-to-high-end residences, media rooms, or professional home theater environments. At the same time, traditional ceiling fans have seen little fundamental change over the past several decades, remaining primarily air-circulation fixtures. WindGroove raises a new question of whether the ceiling can move beyond being a place to hang a fan or light, and become a more accessible entry point for home entertainment, comfort, and atmosphere.

AirFi One was created from this idea. By integrating audio, a main light, RGB ambient lighting, and a fan into one ceiling-mounted system, it allows users to experience immersive sound, adaptive lighting, and comfortable airflow without complex renovation or multiple separate devices. More than a functional upgrade to existing categories, AirFi One introduces what WindGroove calls a Ceiling Vibe System — a new approach that brings sound, light, airflow, and atmosphere control into a single overhead experience. For WindGroove, this is the first step toward a broader vision: “Ceiling as an Experience Layer.”
In everyday family life, AirFi One changes not only where sound comes from, but how it exists within a room. During gatherings, music can naturally diffuse from above and become part of the living room atmosphere, rather than coming from one corner in a single direction. During movie nights or gaming sessions, sound can fill the space more evenly, helping users feel closer to the content. The acoustic system with Jamo acoustic tuning helps balance vocals, low frequencies, and high-frequency details, while DSP processing optimizes the soundstage created by the ceiling position. With a 45Hz–20kHz frequency response and THD not exceeding 1% distortion, AirFi One is designed to deliver clear dialogue and an immersive listening experience across gatherings, movies, and gaming.

Beyond audio, AirFi One supports daily comfort through powerful airflow and integrated lighting. Its fan system provides up to approximately 4621 CFM airflow, with 6-speed control and forward/reverse operation, allowing users to adjust air circulation based on seasons, room conditions, and daily routines. Its 15W LED main light delivers approximately 1200lm of brightness for everyday illumination, with warm, natural, and cool light options, plus 10%–100% stepless dimming for work, dining, relaxation, or movie nights. The RGB ambient lighting supports six switchable modes and music sync, allowing the room to shift into different atmosphere states as scenes and music change.
AirFi One also carries a distinctive technological aesthetic. Its transparent fan blades reduce the visual heaviness often associated with traditional ceiling fans, making the product appear lighter and more modern overhead. The gray audio body reinforces a sense of technology and futurism, distinguishing AirFi One from conventional home appliances while allowing it to integrate naturally into the home environment. For users, choosing AirFi One is also a statement of lifestyle: a willingness to embrace new forms of home experience and define living spaces through products that reflect design awareness, forward-looking taste, and modern home attitudes.

In terms of control, AirFi One emphasizes simplicity and intuition. It supports App Control, Remote Control, and Voice Control, allowing users to choose the most convenient method for their habits and existing smart home environment. Users can adjust scenes through the mobile app, quickly switch functions with a wireless remote, or use voice control through Alexa and Google. One-Time Setup also remembers commonly used lighting, fan speed, and audio settings, helping the room maintain a consistent atmosphere without repeated adjustments.
AirFi One reflects WindGroove’s larger brand philosophy: “Beyond Devices. Into Sensory Experience.” For the brand, technology is not only about specifications or connected features, but about how a product changes the feeling of a space. WindGroove aims to develop products that merge utility with atmosphere, bringing together design, comfort, entertainment, and emotional resonance.
WindGroove also brought AirFi One to CEDIA Expo this September, showcasing the product at Booth #3043 to professionals and partners across the smart home, home entertainment, and residential technology industries. The exhibition provided an opportunity for WindGroove to introduce its ceiling-based experience concept to a broader industry audience and highlight AirFi One’s potential across connected home, residential audio, and modern living environments.

WEB3GUARANTEE Launches: A Decentralized Custody Trading Platform Reshaping On-Chain Transaction Trust with Smart Contracts
Recently, the decentralized custody trading platform WEB3GUARANTEE officially opened its services to global users. Leveraging smart contract technology, the platform creates a non-custodial on-chain escrow trading system, providing secure and verifiable trading solutions for physical goods, virtual goods, and auction transactions in the Web3 space. It aims to address industry pain points such as centralized control of funds by traditional trading intermediaries, opaque transaction processes, and unfair dispute resolution.

According to its official website, WEB3GUARANTEE’s core highlight lies in its non-custodial contract mechanism. The platform itself does not touch or hold any user assets; all transaction funds are locked and held in custody by smart contracts, eliminating the risk of platform misappropriation of user funds. After a transaction is completed, settlement is automatically executed by the on-chain contract. All transaction records are recorded on the blockchain, immutable, and fully transparent and verifiable, entrusting transaction trust to code execution and eliminating dependence on centralized institutions.
The platform features a standardized four-step transaction process, covering the entire chain from order creation to settlement: both parties jointly confirm the transaction terms and create an order; the buyer’s funds are deposited into the contract escrow; the seller completes delivery, and the buyer confirms receipt or initiates a dispute; after confirmation, the contract automatically releases funds. The entire process is logically clear, allowing ordinary users to quickly get started.
To address the frequent disputes in transactions, WEB3GUARANTEE has established a neutral arbitration mechanism. In the event of a dispute, an arbitration panel of 13 arbitrators will conduct a collective vote to adjudicate the dispute, with comprehensive time rules in place: a 24-hour evidence submission period, a 48-hour arbitration voting period, and a 7-day arbitration application window for both buyers and sellers. It also includes penalties for incorrect voting and a cooling-off period for arbitrator applications to constrain the behavior of arbitrators, ensuring a professional and impartial adjudication process and preventing bias towards either party.
The platform has implemented differentiated automatic confirmation mechanisms for different product categories, catering to the real-world needs of various scenarios. Physical goods, auction items, and regular purchases are automatically confirmed after 15 days; virtual goods transactions are automatically confirmed after 1 day, adapting to the instant delivery characteristics of digital products. WEB3GUARANTEE defines complete contract parameters, including buyer confirmation timeout, merchant deposit unfreezing and cooling-off periods, product delisting cooling-off periods, and auction delivery time limits. All rules are written into the on-chain contract, and the rules and fees are transparent and publicly available, allowing anyone to directly read and verify the on-chain contract parameters.
Regarding risk control, WEB3GUARANTEE introduces a merchant deposit system to penalize merchants who violate regulations, thereby protecting the rights of counterparties. It also sets limits on the number of products that can be listed: sellers without deposits can list a maximum of 5 products, increasing this to 20 after depositing deposits, thus constraining seller behavior and reducing the risk of malicious orders. The auction module also includes complete risk control parameters, such as the maximum auction period, anti-sniping window, and payment time limit thresholds, to prevent malicious operations in auction transactions.
In terms of open-source governance, WEB3GUARANTEE has made its contract and front-end code fully open-source, with an open GitHub repository, accepting community audits, public supervision, and developer contributions. It also provides access to audit reports and Telegram community channels, following a community-driven approach to overcome the drawbacks of closed-source platforms operating in a black box, further enhancing the platform’s credibility.
The platform employs a strict fund segregation mechanism. Each transaction’s funds are held in escrow by independent smart contracts. Merchant margin deposits and user transaction funds are completely separated and managed independently. Any fund issues in a single transaction will not affect other transactions or margin accounts, eliminating the risk of collateral damage.
Industry analysis points out that centralized escrow trading models are always vulnerable to platform misconduct, platform collapse, and opaque arbitration. WEB3GUARANTEE solidifies all fund custody, settlement, and arbitration rules into on-chain smart contracts, using code to constrain all parties involved in the transaction, providing a new approach to Web3 P2P transactions. As the project continues to iterate, this platform may become an important infrastructure option in the P2P on-chain escrow trading sector, helping global users conduct safer and more reliable decentralized transactions.
