The encrypted asset trading platform is an important channel connecting miners and encrypted asset users. Ordinary users have no opportunity to invest in mining machines and can only choose to purchase encrypted assets to participate in the blockchain industry. On the other hand, miners, which should be the most important link in the blockchain industry, are niche and marginalized. In fact, we can see in the Bitcoin white paper that the most important feature of Bitcoin is that everyone can participate in mining, instead of being monopolized by several large mining pools, which is very unfair to ordinary people.
At present, all mainstream exchanges are not fair and opaque, which runs counter to the concept of blockchain technology and the autonomous newcomer mechanism. Borderless on-chain exchanges are emerging in the industry with their unique advantages. Bullcoin borderless on-chain exchanges are born at the right time, and will lead the industry with their strong technical strength and the concept of fairness, democracy, justice and transparency.
In order to seek greater breakthroughs, the data storage exchange will develop the DAcoin exchange, an infrastructure full ecological chain exchange suitable for the digital economy trading environment.

DHARIN Launches Lab Grown Diamond and Gemstone Fine Jewelry Collection for Everyday Wear
United States, 11th Nov 2026, Grand Newswire – Fine jewelry brand DHARIN today released its first collection. Designed for everyday wear, the collection centers on lab-grown diamonds and lab-created sapphire, emerald and ruby, and is now available through mydharin.com to customers in the United States and Europe.

DHARIN’s pieces sit between fashion jewelry and traditional fine jewelry. The brand holds that fine jewelry need not be reserved for engagements or formal occasions, and can instead become an everyday choice, much like a classic piece in a wardrobe. The collection follows fine jewelry standards in its materials and settings, while its design takes cues from the way fashion is worn: each piece can be worn alone or stacked.
This approach shapes the brand’s choice of materials. Lab-grown diamonds share the same crystal structure, refractive index and hardness as mined diamonds, and lab-created sapphires, emeralds and rubies share the same composition as their natural counterparts. The difference lies in origin: lab-grown stones require no mining, and their growth process is fully traceable.
DHARIN views lab-grown stones as part of a more considered approach to fine jewelry, in which value comes from design, craftsmanship and wear, not from rarity alone. The same budget can allow for a larger stone or a higher grade, bringing D color, high clarity diamonds into everyday jewelry. Design is also less constrained by the cost of rough material, leaving more room to explore cut, proportion and color. Lab-created colored gemstones offer consistent color, allowing pieces in the same shade to sit together in harmony.
DHARIN regards jewelry as something to be worn rather than an investment, and encourages customers to build a collection over time, in keeping with their own style and pace of life.
The first collection is built around earrings and extends to rings and bracelets. The lab-grown diamond pieces center on three four-prong solitaire stud earrings, ranging from a 1 carat total weight round brilliant cut to a marquise cut and a 4 carat total weight oval cut, all in D color. The colored gemstone pieces include halo stud earrings, a halo ring and a tennis bracelet, each offered in sapphire, emerald and ruby. The halo pieces use a low setting suited to everyday wear. The collection is offered in metals including rhodium-plated sterling silver, 18K gold vermeil and 14K gold.
Each DHARIN product page lists the stone type, carat weight and metal, with color and clarity grades included for diamond pieces. Every lab-grown diamond of 0.50 carat and above is accompanied by an individual grading report issued by the International Gemological Institute (IGI). IGI is an independent gemological laboratory, and DHARIN is not affiliated with IGI. All colored gemstones in the collection are laboratory-created and identified as such on each product page, and brand certificates can be provided upon request.
The name DHARIN, pronounced DAR-in, is derived from a Sanskrit root associated with holding or sustaining, and is similar in sound to the English word “darling.”

Rantizo (Nasdaq: RNTZ) Advances U.S. Production of Heavy-Lift Autonomous Drones After $258.8 Million Acquisition, Targets California’s $61.2 Billion Agricultural Market
Houston, Texas, USA, November 11th, 2026, FinanceWire
California’s Central Valley to serve as U.S. launch market for the Houston-built Harvest 100, a heavy-lift agricultural drone with more than 70% U.S. or allied parts designed to cover 500 acres per day; Rantizo holds master spray agreements with Nutrien and Helena
Rantizo (Nasdaq: RNTZ) (“Rantizo” or the “Company”), the Houston-headquartered builder of American-made heavy-lift autonomous drones, today announced plans to expand its agricultural drone services into California’s Central Valley, which will serve as the U.S. launch market for the Harvest 100, the Company’s U.S.-built heavy-lift agricultural drone. The announcement comes one month after Rantizo completed its $258.8 million transaction and began trading on Nasdaq under the ticker RNTZ.
The Harvest 100: American-Made Heavy Lift
Rantizo designs and builds its aircraft in Houston, Texas. Its flagship, the Harvest 100, is a heavy-lift, autonomous agricultural drone built in America with more than 70% U.S. or allied parts and designed for FAA and NDAA compliance. Each Harvest 100 is designed to cover 500 acres per day, and the platform is built to be BVLOS-capable and swarming-ready, with modular payloads that carry it from spraying and seeding into forestry applications.
Rantizo is an approved drone application provider under master spray agreements with Nutrien and Helena, two of the largest agricultural retailers in the United States, positioning the Company to serve their grower networks. Rantizo is also seeing strong grower interest heading into the upcoming season, with drone sales agreements in place, multiple successful field trials, and FAA certifications and operational authorizations in more than 15 states. Growers and ag retailers can hire a Rantizo field team by the job or by the season, or buy, lease or finance the aircraft and fly it themselves, with pilot training available.
“America needs American drones, and we are building them in Texas today,” said Marianne McInerney, President of Rantizo. “The acquisition and the new ticker were the starting line. Behind them is an American shop floor, an American-made heavy-lift aircraft, and master spray agreements with two of the country’s largest ag retailers. California is where the Harvest 100 launches: the most valuable farm economy in the country, served by an American drone. As foreign aircraft are priced and regulated out of this market, Rantizo intends to be the American name growers and ag retailers call first.”
Harvest 100 U.S. Launch Market: California’s Central Valley
Rantizo plans to bring its agricultural drone services to California’s Central Valley, beginning with four adjacent counties: Fresno, Tulare, Kings and Kern. California is the nation’s leading agricultural state, with $61.2 billion in farm and ranch cash receipts in 2024, more than 400 commodities and more than three-quarters of the country’s fruits and nuts, according to the California Department of Food and Agriculture.
The corridor’s almonds, grapes, pistachios, citrus and vegetables are high-value specialty crops where precise, timely aerial application matters most, and where orchards, vineyards and wet or constrained ground can limit conventional equipment. Concentrating on four neighboring counties allows Rantizo to serve the region with mobile two-person crews and shared equipment rather than separate fixed operations.
The entry is phased and tied to contracted demand. Rantizo intends to work with experienced California license holders and its master spray agreement relationships with agricultural retailers to establish licensing, county registrations and channel partners, beginning operations with two drone pilot crews and scaling to as many as four crews across the corridor during the upcoming season as contracted acreage grows. The service business is also built as a direct sales channel for the Harvest 100: paid applications and field demonstrations introduce growers to the aircraft and build a pipeline for purchases, leases, pilot training and long-term service programs.
Federal Policy Is Shifting the Market to American-Built Drones
Federal policy has moved decisively toward domestic aircraft over the past 18 months. Executive Order 14307, “Unleashing American Drone Dominance,” directed federal agencies in June 2025 to prioritize U.S.-made drones. In December 2025, the Federal Communications Commission added foreign-made drones and critical drone components to its Covered List, barring new foreign models from equipment authorization unless exempted. And since September 3, 2026, imported unmanned aircraft with a maximum take-off weight above 25 kilograms face Section 232 tariffs of up to 100% under Presidential Proclamation 11055.
The market those rules protect is growing fast. The Federal Aviation Administration forecasts that the active U.S. fleet of large drones, those over 55 pounds, will grow from 8,295 aircraft in 2025 to 55,509 by 2030. The Harvest 100 is built for exactly that weight class.
Built on the $258.8 Million Transaction
Rantizo’s public listing was established in October 2026, when the Company completed its approximately $258.8 million acquisition of the drone assets of Houston-based Rantizo, Inc. and adopted the Rantizo name. Rantizo, Inc. received 51,966,591 newly issued Class A ordinary shares and held approximately 87% of the Company’s Class A shares following the closing, and those shares are subject to a six-month lock-up. The Company’s shares have traded on the Nasdaq Capital Market as RNTZ since October 13, 2026.
The Rantizo name has been field-proven since 2018, when it was founded in Iowa City as a pioneer of agricultural drone spraying. The Company is led by President Marianne McInerney, a former U.S. Department of Transportation official.
Rantizo expects to provide further updates on its California launch, commercial orders, production and deliveries as they are finalized.
Global Communications and Partnerships
Phoenix MGMT & Consulting has transitioned with the Company from SKK Holdings to Rantizo and continues to support its overall growth and global expansion, leading global communications, public relations and global partnership development. Phoenix’s work includes introducing Rantizo to prospective supply, manufacturing and technology partners across the drone, defense and advanced-materials sectors.
About Rantizo
Rantizo (Nasdaq: RNTZ), headquartered in Houston, Texas, designs and builds heavy-lift autonomous drones in the United States for precision agriculture, forestry and wildfire response, infrastructure inspection and specialized government applications. Its platform includes the U.S.-built Harvest 100 agricultural drone, the Titan firefighting and forestry drone and a long-range fixed-wing surveillance prototype, supported by field services and by purchase, lease and financing options.

Zen Trinity: wallet live, card via licensed issuers, exchange opens trading on one chain
VANCOUVER, British Columbia, 11th November 2026, People paid in USDT, holding it or trading it now have a published status for each of Zen’s three retail products. ZenWallet, a self-custody wallet with no seed phrase, is live at app.zenwallet.io and on Telegram at @zenwalletbot. ZenCard, a Visa card in virtual and physical form, is issued by licensed financial institutions in the countries they serve. ZenX.tel, the Zen Telegram Mini Exchange, has opened trading on BNB Smart Chain at @zenexchangebot, in an early release gated by region and identity. Zen calls the three its Trinity; this release states where each one stands.

Why does it matter? A stablecoin balance is only useful if it can be held without a seed phrase to lose, spent without a manual cashout first, and bought or sold against the money a person is paid in.
ZenWallet, live. The signing key is split into three shares (device, ZenWallet server, backup recovery service) under 2-of-3 threshold signing, so no single party, Otaro Pay Ltd. included, can move funds alone. On Ethereum, Polygon and BNB Chain only, the network fee is quoted in USDT before signing and settled by the wallet. Sending and receiving carry no ZenWallet fee. Daily spending profiles cap at USD 5,000 or USD 50,000, with a second factor above USD 1,000 and USD 5,000 respectively; recovery runs through named guardians or trusted contacts plus a passkey or hardware key. Cashout to a bank account is built in for countries where the route is live, as at 10 November 2026.
ZenCard, issued by licensed institutions. The card settles in local currency at the till and is funded from Bitcoin, Ethereum and USDT balances. The holder sets daily and monthly caps and merchant-category restrictions. Fees, limits, rates and eligibility are set by the issuing institution and disclosed in its terms before application. Otaro Pay Ltd. operates the ZenCard website and does not itself issue cards. Visa acceptance in more than 100 countries is not the same as eligibility to be issued a card: availability varies by country.
ZenX.tel, trading open in early release. On BNB Smart Chain, identity-verified users trade USDT peer to peer: the seller’s USDT sits in on-chain escrow until the seller confirms payment or an arbitrator rules, and local currency moves between the two people, outside Zen’s systems. Spot and swap are in beta. One perpetual market, ETH, is tradeable; perpetual contracts involve leverage and can cause rapid loss, including full loss of margin, and the margin sits in the exchange’s contract with Zen’s pool as counterparty. Users sign every fund-moving action in their own wallet; the app never holds a private key. Platform fees under the 8 November 2026 schedule: P2P buyers none; sellers none for 90 days from launch, then 0.25 percent; spot and swap 0.25 percent on the USDT leg; perpetuals quoted per order; deposits none; withdrawals network cost only.
Each statement rests on a published page: zenwallet.io/security and zenwallet.io/press, zencard.online, and zenx.tel, which labels each component live, beta, in review or planned.
Three questions to ask any multi-product crypto launch, including this one. Who holds the key, and can any one party move the funds alone? Who issues the card, under whose licence, and in which countries? What is live today, what is in beta or planned, and where is that written down?
“Three products announced together are three claims, not one,” said Poonam Jaiprakash, Group Director. “We would rather tell a reader the exchange is in early access and the card depends on an issuer in their country than let them find out after they have moved money. The wallet is called live because it is finished; the other two will be called live on the day they are.”
“The hardest work in the Trinity is the work nobody sees,” said Arjun NK, Tech Director, Zen Atlas Group. “A lost phone, a disputed trade, a transaction that does not match its quote. Our engineers put their hours there, and what is not finished still says beta.”
Where it does not apply. No route between the products is claimed: funding a ZenCard from ZenWallet, or signing ZenX.tel trades with it, will be described only once that exact route is verified. ZenX.tel is an early release on one chain; TON, an independent audit, a bug bounty and proof of reserves are labelled planned, and its blocked-country list is not published. Because ZenWallet is self-custody, nobody, the company included, can reverse a transaction. This announcement describes what three products do and cost; it is not an offer of a token, an investment or a return, nor a recommendation to trade.
To check availability: zenwallet.io/get-started, zencard.online and zenx.tel/availability
