What our customers say

The Goldshell DG Card exceeded my expectations. Been running smoothly since I plugged it in. Great experience with BullMiners from start to finish. Will definitely order again from BullMiners.

Replaced an older unit with this one. Second time I've done business with Bull Miners, both smooth.

Two months in and no complaints. At 65 dB it's tolerable in an outbuilding. 21energy's firmware isn't fancy, but it's reliable. SHA-256 machines all look the same on paper, the hosting cost is what actually decides it. Better experience than I've had with two other shops I won't name.

Ordered on a Tuesday, delivered by the following Monday. The PSU handles surges without issue. Reading 336Th/s steady on the pool. Difficulty is brutal right now, but the machine is doing its job. Their installment option is what made the purchase possible for me. Would encourage a friend to buy from here.

Been mining for years, this is a solid addition. The PSU handles surges without issue. Pinecone's firmware isn't fancy, but it's reliable. Firmware UI could be prettier but functionally it does everything I need.

Bought this after reading a couple of comparisons. The noise dampening on this model is a real difference. Merged LTC/DOGE payouts arrive together, no messing about. They didn't try to upsell hosting when I said I was running it at home. Worth every euro so far.

Shipped to Portugal, arrived in six working days. Fan bearings sound healthy, no whine so far. Draws 2500 W at the wall, matches the plate. Sent it to the Georgia facility — power bills are a memory. Support was slow the first time I emailed but nailed it the second. Recommended if you know what you're doing with power planning.

Delivery to Germany took eight days door to door. Coolant loop is holding pressure and the flow rate matches spec. Another ElphaPex for the Litecoin / Doge side of the fleet. Merged LTC/DOGE payouts arrive together, no messing about. Their installment option is what made the purchase possible for me. Solid buy at this price.

First unit I've bought from Bull Miners. Web UI is basic but it works. Aleo mining is early enough that I'm mostly holding what I mine. Ben on the sales side answered every question before I bought. Running it under their hosting plan in Iceland, first payout hit on schedule. Solid buy at this price.

Was a bit nervous about ordering hardware this size online. Acoustically nowhere near a standard Antminer, night and day. WhatsMiner's firmware isn't fancy, but it's reliable. SHA-256 machines all look the same on paper, the hosting cost is what actually decides it. Their installment option is what made the purchase possible for me. Running it under their hosting plan in Iceland, first payout hit on schedule. Would have loved a spare fan bundled in — small nit. Not a beginner box but a great value for the tier.

Satisfied with this purchase. Pinecone Matches INIBOX 850Mh/s 500W INI is doing well mining crypto. Getting stable performance numbers around the clock. I wished the PSU was included separately but overall great.

Straight-forward experience from checkout to plug-in. Recommended if you know what you're doing with power planning.

First unit I've bought from Bull Miners. Web UI is basic but it works. Draws 1900 W at the wall, matches the plate. ETC mining is niche now but this unit is efficient enough to make it work. Return policy was refreshingly readable. Will be back for another once I've paid the first one off.

It's living in a colo rack, not at home. At 65 dB it's tolerable in an outbuilding. Draws 5510 W at the wall, matches the plate. Difficulty is brutal right now, but the machine is doing its job. Their installment option is what made the purchase possible for me. Not going anywhere else for the next one.

Bought this after reading a couple of comparisons. Hashrate has been steady at the stated number, sometimes a touch above. Kaspa hashrate has grown so fast I'm glad I got in when I did. Machine arrived with the original manufacturer seals unbroken. Genuinely one of the easier hardware purchases I've made.

Very happy with this purchase. VolcMiner D1 Hydro (30Gh) performs exactly as advertised. Setup was straightforward with the included manual. Will order from BullMiners again for sure.

Straight-forward experience from checkout to plug-in. Hashrate has been steady at the stated number, sometimes a touch above. Reading 115Th/s steady on the pool. Bitcoin pool is FoundryUSA and shares are landing every few seconds as expected. Ben on the sales side answered every question before I bought. Happy with the whole process.

Top-notch equipment from BullMiners. My Bitmain Antminer E9 2.4Gh/s 1920W Ethash ETC has been running 24/7 without any issues. Hashrate is exactly what was promised.

Was skeptical at first but the Canaan Avalon Nano 3S proved itself. No complaints about performance whatsoever. Packaging was professional and secure. Top marks across the board.

Was on the fence for a few weeks before pulling the trigger. Firmware update pushed on day one, worked without bricking anything. Draws 1280 W at the wall, matches the plate. I ran the numbers on three calculators before ordering, all landed close to the site's own. Shipped from the EU warehouse so no import duty surprises. Recommended if you know what you're doing with power planning.

Bought two, keeping one, hosting the other. Temps under load sit lower than I expected. Draws 7200 W at the wall, matches the plate. Wire transfer took a day to clear, packing began the next. Hosted mine at their Bhutan site, uptime has been genuinely 99%+. No complaints, would order again.

Been running mine for about six weeks now. Efficiency is exactly where the spec sheet said it would be. Another Bitmain for the Zcash side of the fleet. Equihash-only, and the Zcash side of things has been stable enough to justify it. Invoice was clean and matched exactly what I was quoted. Dashboard for the hosted unit shows shares in near real-time, which was a nice surprise. Docs on the manufacturer side are thin, expect to Google a few things. Recommended if you know what you're doing with power planning.

Came double-boxed with all the accessories. Fans are loud, no getting around it, but that's the coin's problem not the vendor's. Draws 1550 W at the wall, matches the plate. The Zcash algo hasn't been touched in a while, so I feel OK about a multi-year hold. Even split the payment across two methods without any drama.

Looked at the same model on three other sites. Hashboard temps are even, all three boards inside 4°C of each other. Solo hopes are zero but that isn't why you buy one of these. Payment via BTC went through in one confirmation. Second time I've done business with Bull Miners, both smooth.
