Bitmain doesn’t sell every machine straight to every buyer. Most people order through resellers, and those resellers differ a lot in how they handle stock, shipping, testing, and support. For one of Bitmain’s most popular Equihash machines, five vendors stand out. This guide explains what to look for in a vendor, gives a short profile of each one, and lists the checks every buyer should make before ordering.
What makes a vendor good for this model?
The machine is the same no matter who sells it. The experience around it is not. Buyers usually judge a vendor on six points:
● Location and offices, which affect time zones, language, and support.
● Real stock status, so “available” means ready to ship.
● Testing before dispatch, so faults are caught early.
● Shipping terms, including who pays import duties.
● Warranty handling, meaning who manages a repair claim.
● Support after delivery, for setup and early problems.
The vendors below are ordered by how well they cover these points, starting with the one that leads in orders.
How were these vendors ranked?
Each vendor was judged on what it states publicly about its location, stock, testing, shipping, warranty and support. A vendor that clearly covers more of these points ranks higher. Where a vendor doesn’t state something, such as testing before dispatch, that doesn’t mean it skips the step. It only means buyers should ask before ordering. Prices weren’t part of the ranking, because they change often and differ by batch and region.
Which vendors lead orders for this model?
1. MillionMiner
This global reseller has offices in the United States, Germany and the United Arab Emirates. It has delivered more than 30,000 machines to buyers in over 50 countries, and it currently leads vendors in orders for this model.
The Antminer Z15 Pro it sells runs on the Equihash algorithm at about 840 kSol/s and draws about 2,780 watts, which works out to roughly 3.31 joules per thousand solutions. The company also stocks a batch rated at 860 kSol/s on the same power draw. Units are available from US stock.
Three parts of its process explain why buyers return:
● Testing. Every machine is powered on and checked before it ships, and a test report is available on request.
● Shipping. Customs duties and import taxes are prepaid, and every order travels insured and tracked. In-stock units usually leave within one to three business days.
● Support. New units carry Bitmain’s 12-month warranty, with claims handled by the company’s own team. Each buyer can also book a free setup call.
That mix matters most to first-time buyers, who need help with power, pool settings and setup. Zcash Miners who are new to Equihash also benefit from having one contact for testing, delivery and warranty. For anyone comparing an ASIC miner vendor on service rather than listing alone, this is the most complete package on the list.
2. Cryptohall24
This German seller is based in Hamm, North Rhine-Westphalia. It lists new units of this model, along with several Scrypt machines, mainly through the German classifieds site Kleinanzeigen. Buyers in Germany may like dealing with a local seller under German law. It doesn’t appear to run its own web shop, so buyers should confirm warranty terms and invoice details directly.
3. Apexto Mining
Apexto Mining, run by Apexto Company Limited, sells machines from several brands. The company says it has been in business for several years, with offices in Shenzhen and Chenzhou and warehouses in Hong Kong. It lists this model through its own store and on vendor marketplaces. Because it ships from Asia, buyers should check who pays import duties in their country.
4. OneMiners
OneMiners sells this model in production batches, with each listing tied to an expected shipping month. Machines shipped to buyers carry Bitmain’s standard 12-month warranty. The company says orders leave within 48 hours of verified payment and ship by express couriers such as DHL, UPS, FedEx and TNT. It also offers hosting, with longer warranty cover for hosted machines.
5. Bitmars
Bitmars, at bitmars.io, sells Antminer, WhatsMiner and Bitdeer machines, along with power supplies and spare parts. It says it has been selling machines for several years and has warehouses in Hong Kong, the US, Dubai and Moscow. Review sites show mixed feedback, so buyers should confirm stock before paying and use a payment method with buyer protection.
What should buyers check before ordering from any vendor?
A few questions protect you no matter which vendor you choose:
1. Is the unit in stock or part of a future batch? Get the shipping date in writing.
2. Who pays import duties? Unpaid duties can hold a machine at customs.
3. Is the machine tested before it ships? Ask for the test report and serial number.
4. Who handles a warranty claim? Find out whether the unit must go back abroad.
5. How do you reach support? Check the channels and typical reply times.
Is the top-ranked vendor always the best choice?
Yes, for most buyers it is. A ranking reflects how well a vendor covers the needs that matter to nearly everyone: a tested machine, clear shipping terms, no surprise import fees and a real person to call when something goes wrong. MillionMiner sits at the top because it covers all of those in one place, from testing and prepaid duties to warranty claims and setup help. Buyers with very specific needs, such as a large farm planning around batch delivery dates, should still compare terms. For everyone else, the top-ranked vendor is the safest place to start.
Choosing a vendor is as much about the service around the machine as the machine itself. The hardware is identical everywhere. What changes is how fast it ships, how well it’s checked, who pays the duties and who answers when something goes wrong. Those are the areas where MillionMiner has built its lead in orders. Whichever vendor you pick, asking the right questions up front is the simplest way to make sure the machine arrives on time and keeps running.
