Crucible & Devotion points

So I just started on the new DLC and I’m trying to level up a character solely inside the Crucible.

As I understand it, you can buy all your Devotion points for Tributes there, while still being able to use the character in normal Campaign mode.
Does this mean I can take one of my Campaign characters to the Crucible to farm some Devotion points and save the time that it would take to hunt down all the missing altars in the Main Campaign?

You don’t really get lots of xp from crucible. Also it would get boring really fast if you stay in crucible forever.

Yes you can indeed

They didn’t ask about XP… They didn’t ask if anyone else would find it boring… and there was no mention of staying in the crucible for ever.

What might be boring for you doesn’t mean that it’s going to be boring for someone else.
