If you persist in calculating with satoshi you are right. But then you deserve that loss because of stupidity.
The average price in sept 2017 was 0,1015, The price now is 0,1155 so you have a profit instead of a loss.
Its even worse if you look a the btc value against Dollars then and now. 🙈🔫
Buy on Nocks with Euros. Much simpeler and no extra devalualion risks of Bitcoin. Just have some patience, you will be OK.
