Thanks! Payment received. The amount is lowering. According to my calculation, it would take approximately 3 years to get what we invested. 
I think, we will have to wait for a looong time...

It all depends on when you invest and what your assumptions are. The people who invested in February broke even in July. On the flip side, if you invested in July and always have 20% difficulty increases, you will never break even. Let's hope difficulty is more gentle than that.
With a 1TH contract, I'm not sure you would earn anything significant after the second year. Time will tell. I'm not sure how you arrive at your 3 year break-even figure.
