whats great value for ripple

Considering the high quantity of XRP that exists, that a large portion is held by a small number of entities, and that Ripple will want a stable XRP price in order to be useful to the banking sector, what is a reasonable price fr XRP to stabilize at? XRP has mooned this year, and people want it to moon further, but at a practical level I'm interested to see where people can rationalize it stabalizing. Would $0.50 or $1 or $100 or $1000 be better for banking transactions? And have the owners of Ripple made any comment on this?
