That question might feel a little stupid, but I want to be sure.

So. I have a jaxx wallet. There is a bitcoin address and its private key. So can I just copy the address from there and submit it to the nvo.io as a personal bitcoin address? And also can I sent bitcoins from that jaxx wallets very same bitcoin address to the nvo.io crowdsale?

Another question. There are two bitcoin addresses in jaxx wallet. For some reason. What if I submit one of those address to the nvo.io as a personal bitcoin address and sent the bitcoin from another bitcoin address  in the jaxx wallet. Is there any promblem? I guess no. I hold the private keys of both of those addresses in the jaxx wallet.

I just want know that I have understood right.
