Facebook’s cryptocurrency launched this week. It is called Libra and, as the name implies, promises freedom. Going by Libra's aims, the currency could do great good in the world. It could also, however, cause destabilising shifts in power.

Libra appears to be aimed at the unbanked -- the billions of people in the world without access to financial services. The UN estimates 2 billion adults have no bank account and argues remedying this is a crucial part of the fight against global poverty.
