1300 usd earned till unprofitable.
so it should cost 1000 usd...

where i am wrong?

1. Your power cost is too high. At 20c/kwh you probably shouldn't be mining at all.

2. You are probably underestimating the flattening out of the difficulty growth. That is just my opinion though.

If you tweak those you can make this slightly profitable. Not an amazing deal but okay. If BTC prices go up before these sell out they will be a better deal.
