Before you can make $1.6 usd per gtx 1060 but right now you can't make this daily and it seems that you are paying high electricity rate in eur so for me it is not good to mine with this card with your electricity rate unless if you believe on the coin that the price will be increase more in coming months.

I suggest you to wait more months if the bitcoin value increase around $8k mining altcoin with this card might be profitable depends on the difficulty because I'm sure there many investors are waiting in mining to become profitable again.
