Thanks for your reply I didn't said that bitmain is a bigger customer than APPLE AMD or NVIDIA of TSMC and for your information AMD fabricates it's chips from global foundry and not from TSMC Taiwan.
TSMC is running at 65 % capacity and they are taking mining segment seriously and for your information according to TSMC website they have stratified their chip fabrication into 2 divisions one is for mobile phones and the other for high computing power chips.

I think you know nothing about Bitmain mining machines and you are such a novice to mining machine segment and was not accepting this type of statement from a legendary member that bitmain only manufactures a couple of thousand miners each batch WHAT A JOKE
Bitmain has currently 3 active models S9,L3+ and D3  and if you look at bitmain Chinese website and have a common sense to use a Google translator you will know that in each batch their are around 5000 miners and with 3 to 4 batch released every month for each batch it makes around 45000 miners only for Chinese market and the same quantity  for international market it make around 80k to 90k miners and if you multiply it by 189 and 288 chips for some models you will get a hell lot a figure not as big as APPLE but a substantial number.
