I think it would be better to merge systems than to create more currencies ...
Creating a platform where goods and services can be exchanged, not related to fiat money...
CPU-time, content, storage, ...
And reflect the relative value of goods and services in the cost... Fluctuating prices based on the needs, not based on the relation with USD.
Might take some time to reach that point?
Maybe we need a better view on what is the best technical approach first?
