Thankyou for your useful information. Because till now i know for bitcoin mining we need best configuration computer or laptop wven server computer. Without it impossible bitcoin mining. But i know now don’t need high quality device to mining bitcoin any suitable device is enough to set up ASICs. But it is really true Asics need special room like Calm and quiet office where has no any noise. And we have to ensure uninterruptedly electricity. And it is highly cost. If anyone considering thats things he will start mining.
The number of ASICs in bitcoin mining is always increasing. Now you need to buy a new modern ASIC so that it is relevant after the halving, because time will fly by quickly, and then the profit will decrease. I didn’t understand about the office, but ASICs are not installed in office premises.
