I have found that bitcoin mining is good way to earn btc more. How do I do?
I am looking for complete mining guideline. How I find?
BTC mining could be an effective way to earn more BTC only if you get very cheap electricity and low tax rates. I suggest you to give a look to difficulty rate here and to run a few simulation here before investing in BTC-miners. You could find mining help & guides in this forum Mining board & child boards (Mining support, Pools, Mining software (miners), Hardware, Mining speculation).
IMO cheap electricity and low tax rates are a conditio sine qua non for any investment in BTC mining HW. Only after such a preliminary check, I would engage in looking for the best mining HW that suit my business needs by running multiple simulations using HW quotes from multiple vendors. By the while, as I said before in this 3d, I think OP would be better investing in BTC by buying them with fiat currency.
