How do you know his rate for electricity?
What is so difficult in btc mining? You buy a miner, spend 2 minutes configuring it and you let him do the mining.
Once in a while you check on it or when you smell something burning.
No it is not, you spend more time drinking coffee than working on the miners and again, how do you know what price he pays for electricity?
If buying btc will bring you profit because the price goes up, so does mining...spend two seconds thinking before typing.
If you have absolutely no clue, all of you that are posting just to make your quota..
Please shut up!!!!
