Not a silly question. If it's brett, it might well bubble away like that for a couple months. Don't try to bottle it while you still see obvious activity. Brett moves slowly, so the "stable gravity readings 3 days apart" doesn't apply.
It might end up tasting great or it could turn out horrible. The only way to know is to let it go and do what isn't going to do. It also will likely continue to change the longer it sits - even in the bottle.
