I don't think that all those 1,530,000 households should they really install nodes will add too much to degree of Bitcoin decentralization as the latter implies that nodes should be also dispersed over the whole world rather than be placed at geographically narrow area. El Salvador is too small country.
Agree & disagree.
Agree that nodes should be more spread throughout the world rather than just being centralized in one area, because if a blackout occurs there it will turn off all decentralized power in that area. Disagree because according to theory the greater the number of units running nodes, the higher the level of decentralization of a network.
