Anyone here used Bitdeer ASIC miners? I’m curious about their durability. Really interested in the Sealminer A2 Pro, but I want to avoid any gimmicks. Power consumption is 3790W, hashrate 255TH/s, and it’s about $4040 before shipping. What do you guys think?

depends on how long they last. price seems fair. I’d suggest checking the s21 pro, its specs are decent. bitmain has a good rep.

Yeah, I need to think this through. The S21 Pro has lower power at 3300W and a hashrate of 234TH. It’s popular, but costs over $5000. The Bitdeer looks appealing since it’s cheaper. No reviews yet on the A2 Pro, but I found some YouTube videos mentioning it.

Honestly, all miners break fast since they run too hard. I prefer Bitmain because I can adjust the controllers. Makes them last longer. I modded a couple of T21s by downclocking and they work better at lower hashes.

Good info! I thought those controllers were for older miners. A friend used ALTAIR on his S19 and it was solid. Didn't know they worked on S21 too. Appreciate the insight!
