more than 6 hours mining and zero balance whats wrong

What's your hashrate? The network hashrate is over 60 MH/s, even with a high-end CPU you'd likely find only a few blocks a day.
I mine with laptop with 120 kH/s and get 2 blocks in 4 hours, but I get 3 blocks in 4 hours with my server with 80kH/s Speed, it depend on luck
I have ryzen 1700 one on windows who get arround 200khs and second on linux with 300khs. Tested with server who has 2 cpu and that easy get 600-700khs so i can say 60mhs is rly low diff for this coin.
