14 Reasons Why Choose Us

Why Choose Us?

Beware of Unreliable Sellers!

Watch out for random sellers on platforms like Bazoš. You might get a miner, but expect no support, no housing, no assistance (because the “seller” lacks experience), and most importantly, at the first issue, the “seller disappears.”

  • No spare parts, no machine repairs (they have no technicians).
  • No warranty claims – they’ll tell you to send the machine to the manufacturer in China, costing approx. €600 for shipping per miner, 2 weeks there, 2 weeks back, plus at least 4 weeks for repairs = 8 weeks without your machine + €100-300 repair costs.

For Our Clients:

  • Large stock of spare parts available immediately.
  • Spare parts at cost price for post-warranty repairs.
  • Discounts on future purchases!

1. Largest GPU/HDD Rig Manufacturer & ASIC Miner Seller in SK-CZ

We are the largest manufacturer of GPU/HDD rigs and the biggest seller of ASIC miners in 🇸🇰🇨🇿 Slovakia and Czech Republic.

2. On the Market Since 2015

What does this mean for you?

  • Security and reliability for purchases, warranties, and post-warranty services.
  • Extensive experience in building GPU rigs, selecting the highest-quality components, and choosing the best ASIC miners (model/manufacturer).
  • All thanks to years of testing. We know what’s worth it, what’s not, what’s reliable, and what’s risky. We’ve learned the real lifespan of specific ASIC models from various manufacturers and the quality and shortcomings of GPU rig components through experience.

3. Personal Pickup & Payment on Delivery

Stock ASIC miners are always delivered within about 7-10 days (from the supplier’s warehouse). This is the same with us. However, with every other seller, you must pay 100% upfront! Always! With every seller! Full payment in advance! And then, about 7-10 days after payment, the miner arrives.

More Details

With us, delivery is also within 7-10 days, but with a difference: we are the only seller in the entire EU (possibly worldwide) offering payment upon delivery! This means you order a miner, it arrives at our warehouse in 7-10 days, and you pay only upon receipt of the machine, hand-to-hand:

  • Either directly at our location with personal pickup.
  • Or pay the courier upon delivery.

No other supplier, not a single one, offers this option! Not one. And considering that there are literally dozens of fraudulent websites for crypto mining equipment on the internet, paying upfront (often only in BTC) poses a huge risk (see the List of 56 Fraudulent Websites where you’ll see neither the miner nor your money). That’s why with us, you can pay upon receipt of the miner 🙂

4. Buy-Back Option

If you purchase a miner and mining/profits/anything else doesn’t suit you or isn’t for you, we can either buy back the machine ourselves or connect you directly with another buyer.

More Details

Our email database contains over 4,000 contacts, and our Extended Price List is linked from YouTube videos, partner websites, promotional articles, Bazoš, other ad portals, and many other sources… As a result, thousands of people currently have access to it, with hundreds of people from across SK/CZ actually viewing the price list daily! Therefore, we can find a buyer for you or buy the machine back ourselves. It doesn’t matter whether it’s a 3-day-old or a 1-year-old miner.

This option applies to:

  • Miners purchased from us.
  • Miners used for a maximum of 18 months.

5. Warranty & Post-Warranty Repairs

Miners can be repaired like a regular PC, including replacing entire components. Those who know how can even repair/replace the smallest components like microchips/sensors… (of course, this requires know-how). With years of experience with miners, we fully handle these repairs. And because it’s meticulous work, repair costs are, in the vast majority of cases, only €50-200.

6. We’re the Only Seller Who Says DON’T BUY IT!

We understand that the crypto market is still small but growing fast. That’s why the number of newcomers during a bull run grows exponentially. We also realize that many of these beginners don’t know everything they should before buying a miner. But we don’t have the heart to withhold this information before or during an order, even if it means they cancel the order and we lose profits (which they often do). We simply recommend only what we would buy ourselves. Dozens of people have experienced us outright discouraging them from buying miners or convincing them to choose a cheaper (but more effective) model.

Details (Canceled Orders Worth €550,970)

For example:

GPU Rigs: For beginners, this isn’t the best way to start mining crypto. GPU rigs are fine, but compared to ASIC miners, they’re much more demanding to manage or repair during failures. You need to know programming, IT, and hardware, even for a regular GPU rig outage. With ASIC miners, a simple restart is enough (you can’t even do programming with ASICs). Beginners don’t know this and often order GPU rigs (mainly because they’re cheaper than ASICs). That’s why we’ve convinced dozens of beginners to cancel their orders. About 60% of those canceled orders ended up buying a different miner, meaning 40% of orders were canceled = lost profits for us.

Ethereum: March 2021 – June 2021. ETH saw massive growth (from about $300 to $4,000). Mining profits for ETH skyrocketed, and people were buying ETH ASIC miners like hotcakes (A10 500, A10 720…). These were the best-selling miners at the time. But few knew (even advanced miners) that in just 3 months (July 2021), ETH mining profits would drop by 30-50% due to the new ETH protocol – EIP 1559. Even fewer knew that within 6-14 months, ETH mining would end completely (on both GPUs and ASICs). ETH was completely changing its policy and switching to an eco-friendly mining method. And again… since we confirm every order by phone, we couldn’t help but inform customers about these facts. Order after order, one ETH ASIC miner after another. We lost dozens of orders by recommending cancellations! About 78% of people didn’t buy any other miner. Since ETH prices soared, ETH miners were the most profitable on the market (up to 40% more profitable than miners for other cryptocurrencies). With ETH miners written off and other miners offering much lower profits, 78% of people ended up buying nothing. Again, significant profit losses for us, but peace of mind.

Antminer L7 (Dogecoin): When released for sale (July 2021), the Antminer L7 earned up to €37,000 annually mining Dogecoin. And the price? Only €16,800 + VAT. Extremely fast ROI, and people were practically fighting over it. But there’s a catch. Dogecoin is (at least to us) a shitcoin with zero technology and thus no future. Its price spiked for a few months due to Elon Musk’s posts, which also boosted DOGE mining profits to high levels temporarily. But there’s a huge risk going forward – the risk that DOGE’s price will crash back to where it belongs in a few weeks/months (and with it, mining profits). This is exactly what the average beginner doesn’t track. Beginners usually don’t care about the technology or where the cryptocurrency (and thus mining profits) will be in 1-2-3 years. Most beginners don’t do analysis. They only look at today’s numbers, today’s popularity, and believe it’ll be the same or better in 5 years. When we explained this to people, they understood that the L7 might be fine but carries huge risks. In short, another ton of canceled orders. The Antminer L7 was the most expensive miner on the market at the time = the biggest profit for us. In our case, that meant the biggest losses. And like the ETH miner story above, all other miners had almost twice the ROI time, so only about 45% of customers bought a different miner instead of the L7.

In Summary:

We discouraged exactly 27 people (27 official orders) from purchasing exactly 43 miners worth €550,970.

+ Dozens more people who were 95% decided but were discouraged during a phone call (before even creating an order).

Of those, less than half bought another miner (and in most cases, a cheaper one).

So, significant profit losses for us, but peace of mind, a clear conscience, and satisfied customers 🙂

6+. Wait to Buy, Cheaper Next Week

We’re the only seller who’ll tell you: Wait to buy, machines will be cheaper next week.

Why do we do this?

Because manufacturers adjust (must adjust) machine prices based on how much they earn (i.e., based on the current cryptocurrency price on the market). If the market drops, machine prices drop. We buy miners at current market prices and add only a small fixed margin (for warranties, shipping, etc.). So, it makes no difference to us whether you buy a machine now for €10,000 or the same machine a week later for €9,500. Our profit remains the same. But this way, we can save clients hundreds of euros! And that’s why they’re extremely satisfied. That’s why we always openly inform everyone about expected price trends:

  • Wait a week, prices will go down.
  • Buy now, prices are going up in a few days.

7. Free Miner Setup & Operation

We’ll connect and start your miner with you, and show you how to operate it, manage it, and track your profits.

  • Assistance with setting up accounts, pools, and wallets.

8. Guaranteed Lowest ASIC Prices in the EU!

We work with 9 of the largest ASIC miner suppliers worldwide but aren’t tied to any single one. Therefore, we always buy each ASIC model from the supplier offering the lowest price at the time of purchase.

9. Housing Option – Save Thousands on Electricity

Housing Info

10. Up to 2-Year Warranty (Instead of Standard 6 Months)

Up to 2-year warranty for individuals (non-business customers).

11. Personal Approach & Support No Other Seller Offers!

“Buy a miner and don’t bother us anymore…” “Which miner is the best? Obviously the most expensive one.” “Help with wallets, account setup, or mining pools? Do it yourself or pay for it.” That’s how the vast majority of miner sellers operate! The vast majority!
