I want to know how to dig the bitcoin now, how to dig the bitcoin before, how is it different now? Is mining knowledge widespread?
Mining is not profitable now, if you want to invest only one or two mining machines, and if electricity fee is high in your country. Better to rent mining equipment from the farm. More equiments to have, more costeffective to mine.
Who said it is not profitable, if you invest on mining platform you have to invest the big fund for it mate. Please look into right GPU cards or ASIC hardware to start your mining career. I am definitely sure about it. You will get the profit easily bro.
If you can mine in industrial power for mining with the ASIC cards in more numbers. If will give the way to earn more money mate.
