The use of a global currency will be the starting point of eliminating suffering in the world.
If there are poor people, there will still be suffering. The existence of the rich people means poor people will exist also. People can not be equal. That is how the world was crsated. Even rich people can suffer from diseases.
Economically developing nations would also benefit base on the introduction of a stable currency, which would form a base for future economic development.
Like USDT and USDC? They are just like fiat.
It has gotten to a point in life where global currency is now needed in the world in other to end constant inflation and suffering in different countries.
When there is one generally accepted currency in the world, inflation and poverty will no longer be one country fight but a world fight.
Don't you know inflation has benefit also as it has disadvantages? It will be good if crypto and fiat exist together and that is what is happening.
