so the theory goes...
1Th/s brings in say $1000 a month. In two weeks it will only make.. $800... in one month it will only take $640.... in two months .. $409...
wow... this whole game has a six month shelf life. But of course if the value of the each coin/part coin mined increases then it will balance out slightly... i doubt will will see an increase of 20% every two weeks. But we should see something coming back in
If he buys it at 8BTC and he makes 6BTC and sells it back at 3 BTC he won one BTC, you have to compared a BTC amount to the number of BTC he is spending to buy it
