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).
You can find other community websites at
http://nimiq.community/I think Nimiq is among the most profitable coins for some GPUs. If it is profitable at all, depends on your local energy prices etc.
For example, a 1080ti gives you about 300 kH/s on Nimiq, a revenue of about 1500 NIM/day, which is approximately 1 USD/day. The same GPU gives you around 50 MH/s on Ethereum, a revenue of 0.0046 ETH/day, which would be around 0.54 USD/day. RVN would give you around 0.67 USD/day.
