Thus, for an economy to have stability, it needs two things: growth and inclusion.

I think, this is a crucial point. Social stability needs growing economy. Economic growth harms resources. Can we achieve a balance between growth and the environment? Can blockchain and cryptocurrencies contribute to this? I'm not quite sure.

What I have learned is that blockchain and cryptocurrencies can at least lead to more people benefiting from economic growth. That is already a good thing.
