What our customers say

This Bitmain Antminer Z11 135k is a beast! Easy to set up and configure for my pool. Ordered from BullMiners and received it within 3 days. Legitimate business with fair pricing.

The listing was actually accurate for once. Runs quieter than I feared, no worse than a small vacuum. Reading 2Gh/s steady on the pool. Getting into ALEO now vs after mainnet matters, this thing helps me be early. Even split the payment across two methods without any drama.

Bought this after reading a couple of comparisons. Would encourage a friend to buy from here.

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.

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.

Looked at the same model on three other sites. Temps under load sit lower than I expected. Reading 10Gh/s steady on the pool. Signed up for hosting the following week — deployment was quick. Better experience than I've had with two other shops I won't name.

Was on the fence for a few weeks before pulling the trigger. Network stability has been perfect, zero disconnects logged. Draws 7450 W at the wall, matches the plate. Their installment option is what made the purchase possible for me. Not a fault of the vendor, but the fan noise on this generation still isn't for indoor use. Fair price, honest listing, working machine.

Picked one of these up last quarter. Chassis feels well built, none of that thin sheet-metal flex. SHA-256 machines all look the same on paper, the hosting cost is what actually decides it. Customs paperwork was already prepared, courier just needed a signature. Firmware UI could be prettier but functionally it does everything I need.

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.

Been mining for years, this is a solid addition. Coolant loop is holding pressure and the flow rate matches spec. Getting into ALEO now vs after mainnet matters, this thing helps me be early. Invoice was clean and matched exactly what I was quoted. Worth every euro so far.

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.

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

Thrilled with my ICERIVER KS0 Ultra 400Gh/s 100W purchase from BullMiners. Superb quality. Hashrate is rock solid. Couldn't be more satisfied.

Reliable and efficient. The Canaan Avalon A1366 130T 3250W ASIC Hitting the advertised hashrate consistently. BullMiners delivered on time. initial setup required some troubleshooting.

Ordered on a Tuesday, delivered by the following Monday. Runs quieter than I feared, no worse than a small vacuum. Draws 3410 W at the wall, matches the plate. Merged LTC/DOGE payouts arrive together, no messing about. Even split the payment across two methods without any drama. 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.

I've been mining BTC with this MicroBT WhatsMiner M63S 390Th/s 7215W BTC and the returns are excellent. Hitting the advertised hashrate consistently. Smooth transaction with BullMiners.

Been running mine for about six weeks now. Was worth the extra for the newer generation efficiency. Goldshell's firmware isn't fancy, but it's reliable. Scrypt is the algo you want when everything else looks broken. The 1.4c/kWh rate on their hosting plan is what makes any of this profitable.

Looked at the same model on three other sites. At 65 dB it's tolerable in an outbuilding. Another Bitmain for the Bitcoin side of the fleet. Bitcoin pool is FoundryUSA and shares are landing every few seconds as expected. Wire transfer took a day to clear, packing began the next. For once, the product and the description matched exactly.

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.

Incredible hashrate from the MicroBT WhatsMiner M50S 128Th 3276W ASIC! Easy to set up and configure for my pool. Fast EU delivery and great customer support. BullMiners has become my preferred EU mining supplier.

Picked one of these up last quarter. Started producing shares within about 90 seconds of first boot. Another Bitmain for the Bitcoin side of the fleet. Solo hopes are zero but that isn't why you buy one of these. Hosted mine at their Bhutan site, uptime has been genuinely 99%+. Solid buy at this price.

Was a bit nervous about ordering hardware this size online. Firmware update pushed on day one, worked without bricking anything. Reading 6Gh/s steady on the pool. Customs paperwork was already prepared, courier just needed a signature. Would encourage a friend to buy from here.

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.
