Can I find 1 BTC? Which device I need to buy for this. And how long can I find 1 BTC out.
I know we need to invest a lot in mining. But I want to know what to do for 1 BTC.
You can get 1BTC with virtually any bitcoin mining ASIC, but 1BTC in profit is another thing. first we need to know your electrical rate, if it's above .1$/kwh bitcoin mining will be very difficult to accomplish. On the other hand, if it's near 0.02 or something lower then you can make a lot more profit; as of now, if your electrical cost is between those two rates, try considering the A721 from Avalon or the Bitmain Antminer S9.
I have no idea about mining. But I can run the devices without paying for the electricity.
I found two options for the antminer s9. Which one of these should I take.
