It seems the most profitable coin to mine is Kaspa at this moment. Currently, Bitmain and Iceriver produce ASIC miners but when I search for their official website. I found two websites for Bitmain, https://www.bitmain.com/ and https://bitmain.org.cn/ Which one is legit?
Another four websites of Iceriver, https://www.iceriver.company/, and https://www.iceriver.io/ and https://iceriver.eu/ and https://iceriver.cn.com/
Which one is legit?
To answer this question:
For Bitmain, https://www.bitmain.com/ is legit. IceRiver has some fake sites, so be careful there. Their correct site is https://www.iceriver.io/ - I can even confirm that myself because I just ordered there myself 3-4 months ago.
