I´m using Claymore CPU miner with good results for ETN then I started to mine with GPU too, the first was with "ccminer-x64-2.2.4-cuda9"

The config is like this:
ccminer-x64.exe -a cryptonight -o stratum+tcp://etn-au1.nanopool.org:13333 -u etnk4dn7KSiZpTJb7NsLCW2443X97xSReWrKS1FeDP5qZTDtjseg28c25XavdgqvN71tCyz24MCt6YZ UhdzaE2MW8QpPW7bDiB.GTX970/lindahlinvest@gmail.com -p x
pause

Then I tried with "xmr-stak-win64" wich made the config itself so I only needed one miner for both GPU + CPU. Both workers hash around 1000H/s in CMD.

{"pool_address" : "stratum+tcp://etn-eu2.nanopool.org:13333", "wallet_address" : "etnk4dn7KSiZpTJb7NsLCW2443X97xSReWrKS1FeDP5qZTDtjseg28c25XavdgqvN71tCyz24MCt6YZ UhdzaE2MW8QpPW7bDiB.GTX1060", "pool_password" : "", "use_nicehash" : false, "use_tls" : false, "tls_fingerprint" : "", "pool_weight" : 20 },


But there is no GTX970 or GTX1060 worker visible here, it was totally empty during the night. The balance have not moved at all. Where did it go?

The worker 5820K + Ryzen1700 using Claymore CPU. They use this config:
NsCpuCNMiner64 -o ssl://etn-eu2.nanopool.org:13433 -u etnk4dn7KSiZpTJb7NsLCW2443X97xSReWrKS1FeDP5qZTDtjseg28c25XavdgqvN71tCyz24MCt6YZ UhdzaE2MW8QpPW7bDiB.5820K/lindahlinvest@gmail.com -p z -allpools 1 -mport 0
pause

Is it a fake miner I am using so someone else having my coins?

I have tried this version too bot get this line after start https://github.com/tsiv/ccminer-cryptonight/releases
