So basically you're looking for calculator website like whattomine? They also have an ASIC section IIRC. I tried to access the cn domain for Bitmain but it seems their certificate has expired. I'd stick with Bitmain.com as of now. You can also verify it through their social media afaik. As for Iceriver, the website on their social media is the .io one. CMIIW.
I am aware of Whattomine and Asicminervalue. I was confused by the profitability of Bitcoin ASIC miners as the current highest profitable miner is Bitmain Antminer S19 XP Hyd (255Th), which gives $0.31/day after the Electricity cost. I was confused because the profitability is too low compared to other miners like Iceriver which mines Kaspa.
$0.31 a day after electricty is obviously caculated using the electricity price of 12c/kw, try put 0.06 $/kw in the box at the top of the page, most mining companies or hosted miners will be paying that or even less.
Whats interesting is the KS miners didn't scale very well to lower electricty costs, I think the top one only went up by $3 a day, wheras the BTC miners were very sensitive to it. The S19 XP Hyd for example going from $0.83 to $8.56 per day.
