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.
About Iceriver domain, look what
https://iceriver.cn.com/ says about the io domain.
The only official website of the company as of now is:
https://www.iceriver.cn.com/ which had to be rebuilt from scratch. The .io domain is no longer under our control and instead it’s under the control of a scammer! Do not transfer any funds to the accounts featured in www(dot)iceriver(dot)io.
This is the most confusing part as they said they have evidence as well.
Maybe you want to check out this site:
https://www.asicminervalue.com/ - it gives you real-time costs/profit for almost every miner thats available on the market.
I am aware of this website which I also wrote in my original post.
Please check the response above.
https://iceriver.cn.com/ says they are official and the io domain is not in their control anymore.
