What coin to mine?

Is there any profitable coins I could be mining right now? I have 3 GTX1070 TI Founder Editions

I'd recommend focusing your efforts on new coins that pop up instead of mining existing coins. If you want safe coins to mine I'd recommend ETH, ZEC. Focus on low difficulty coins to mine like ZClassic or ETC they'll prove to be more profitable than ETH or ZEC since the difficulties are always rising.
