Hey everyone, is there anyone here that knows about Bitdeer Asic miners? I’m curious about their durability. I’m eyeing their new miner, the Sealminer A2 Pro, but I want to make sure it’s not just another gimmick.
If nobody’s using that one, what’s the next best option? It consumes 3790W and has a hashrate of 255TH/s, priced at $4040 plus shipping.
What are your thoughts?
Anyone using Bitdeer miners here

depends on how long it lasts.
the price is decent.
https://altairtech.io/product/bitmain-antminer-s21pro/
the s21pro is close
Hhmm, I need to thinks bout this very well.
The S21Pro is Bitmain and it a more popular brand compare to Bitdeer, also the power consumption is 3300 while hashrate is 234TH, a bit less powerful compared to Bitdeer hashrate, I ended up telling the fella to go for Bitmain for more reliability and best buy for buck on Bitdeer, because the S21 pro is $5000+ while this new Bitdeer is $4000+
I can't much details about Bitdeer A2 Pro I guess that's because the company is still very new it's a shame, no review from buyers as well but I do find some videos on YouTube and the videos talked about how good and reliable their old A2 with 226TH was.
Thanks for your reply @philipma

No worries. I have found over the years that all miners break to fast as all of them are run too fast.
I like bitmain because I can buy this controller.
https://epicblockchain.io/product/
and down clock them a fraction.
It always seems to make the miner last longer.
some modified t21's
1 board pulled
and the remaining 2 boards clocked to 48th vs 63th.
I will turn 2 t21s into 3 modded t21s
190+190 = 380 hash
down to
96+96+96 = 288 hash
fans are quieter
and power is
3400+3400 = 6800 into 1800+1800+1800 = 5400
Very informative.
I thought those controllers are for old Asic miners only, because I have a friend who used a ALTAIR custom controller on S19 Asic miner and it worked perfectly, I thought that's it, never knew it is available for S21 too.
Thanks for sharing this.
