Don't over-spiritualize Bitcoin. As a money, it would be neither inherently prone to poverty of spirit nor inherently prone to avarice. It's just morally neutral like any other money.
The essence of spiritual poverty, as I have come to understand it, is detachment. So eschewing some amount of monetary gain for the sake of promoting a more just society is compatible with the spirit of poverty.
We have to view money (including Bitcoin) as a resource we must steward rather than as something we own and can dispose of at will.
