Hello;yes;and it cost me 535$.My average mining activity output is about 0.0014176 ETH for each day; and for 2 year; it is about 1.03 ETH( about ~220$).So; not only; I do not gain any profit from this contract; but also; I will lose lots of my asset( 535-220=~315$).Am I right?Please; tell me that; I am doing mistake;thanks.
