Hoe can we exactly answer you? If you want to listen everyone's opinion, then that's mine: As I see usually other altcoins rise after bitcoin. But altcoins are better with functions too at the same time, for example ethereum with it's smart contracts, it's more futuristic than bitcoin but bitcoin gained trust, it's used for dark things really massively and that's the reason why monero is the third coin for me with the potential of rise. From my comment you may understand how I ranked them but overally to my mind these three will be very profitable for long term.
