Funny you trolls blame bitmain for this, bitmain is only doing this cause they know there are idiots with more money than sense, bitmain knows there are desperate idiots that will pay $10000000k for this and will even say thank you to bitmain for scamming me. Scams like this exist because you mindless trolls are greedy and idiots altogether. So, blame you, same thing applies to how overpriced are gpus because of you idiots. Bitmain selling for $12k? that is beer/snack money for them, there were reports bitmain earned as much money as nvidia and nvidia took 20 years to get here, bitmain only took 3 years, so think very carefully before you buy anything from such companies because if you do then next time will not be 12k usd, will be 120k usd.
