TSMC has Bitmain as a low-priority client, and the first one to be cut when demand is high like earlier this year[0]. Bitmain itself is having even bigger reduction in orders to TSMC currently[1] so again, that's the wrong place to look for increased chip demand.

At any rate, I was mostly responding to claims about 'GPUs are profitable for mining' in the parent.

But is TSMC producing these ASIC chips?
