I have a higher Electric rates about 0.21Kw/h

Been mining CN-H algo's with 480's, optimized doing 90-100w

and still, getting some profits, not that much

but is enough to continue mining operations

For me mining still worth it for the miners who has existing and paid off rigs with lower power rates

However, as the concept of adding new rigs, at this point I just prefer to buy coins
