Re: GPU is best or ASIC for mining?

Asics of course but you cant mine everything with Asics

And this area is for Bitcoin only which for the past 4 years or so means using ASICs.
If you want to mine other coins then post in the correct ALTCOIN areas.

Come now, you know very well that most home miners are mining ethereum and either selling it or converting it to Bitcoin.

I know somebody mine the ETH and convert it into Bitcoin Cash. Is that a good idea?

That is a terrible idea, you don't exchange for an alt that is being artificially supported by a few big companies. Without bitmain forcing Bitcoincash for their orders the value would be extremely low.
