Sounds exciting for a dad and daughter hobby. Congrats and I hope to follow in your footsteps when my kids are a little older and know what a computer is. I know many people give negative feedback on minergate, but I have only used that. Yet a lot of crytonote coins on minergate have now increase hash rates, almost 50% increase so I am assuming some of the nicehash users are moving over.
You can also start looking into bitcointalk.com where there is a ton of info regarding where to mine.
thanks mawit07, will check out bitcointalk.com. My daughter actually did her own research on this. Happy to see her really motivated. upvoted and followed
