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
