Wow, I heard about this project back in 2017 and now I found it in Last posts and I can see mainnet started and mining too.
I would like to ask if someone is able to tell me about profitability.
Are there any profitability calculators for this coin?
Mining isn't profitable at the moment. You would find a calculator here:
https://calc.nimiqx.com/Until now, it was only CPU mining (but some people were mining with free VPS trials) and GPU miners came out a few days ago (that's probably why the
hashrate is growing these days).
