I would recommend you to update your blog page, since it contains few outdated information.
3. Can NiceHash mine Ethereum?
Yes, indirectly. NiceHash supports Ethash, the algorithm for Ethereum mining, but payouts are in Bitcoin.
ETH have moved from PoW to PoS in late 2022, so it's impossible to mine Ethereum these days.
4. Can NiceHash mine Litecoin?
Not directly. NiceHash supports the Scrypt algorithm used for Litecoin mining, but earnings are paid in Bitcoin.
5. Can I mine Dogecoin with NiceHash?
Indirectly, yes. Dogecoin uses Scrypt, which NiceHash supports. You’ll get paid in Bitcoin for Scrypt mining.
These days you actually can mine LTC and DOGE together, since DOGE network add merged mining with LTC network.

I'd love to hear your experience with NiceHash or other mining tools. Let’s discuss!
Since your verdict NiceHash is solid option, what do you think about their inactive fee[1] and KYC requirement[2]? Personally i expect some beginner will face issue with those.
