I have 26 GPU. Nvidia and amd mixed. I pay 0.12/kwh and still profitable for me. However I had to improve my GPUs efficiency by undervolting even more. I always do my research and go for promising coins.
As I posted in past:
Yes, It's still profitable.
PoW won't ever become unprofitable*. If that ever happens then people would stop mining. This would lead to difficulty decrease which would make mining profitable again!
Asics and FPGAs are not a big problem as developers are making new mining algorithms every day! It's good to have a versatile hardware for new coins.
*However you'll have to update your hardware as hardware is always improving...
To be honest I really like cryptocurrencies and the concept of proof of work. I don't think I'll ever stop mining. If market crashes like It's happening I'll just do more research.
Anyway If you don't really like wasting your time on mining maybe you shouldn't mine. (at a moment like this)
