Hello, i'm asking if i had 20 K cpu . what is the best coin to mine.
and is it profitable or not
With 20k CPU you could likely make between 30%-50% of the entire Riecoin (RIC) network. Not sure what your power cost would be with 20k CPU's though, but with such a large operation you might expect $1500-$2500/day as long as enough buyers exist in the market.
