Seems like micro-currencies are created to make the local economy more resilient and to reinforce the regional identity.
So it's just a kind of currency that is only used in those 80 regions and not applicable to other regions.
If it is only used to strengthen the region and create a macroeconomy, wouldn't that just override the use of their national currency or they could exchange it for the official national currency. Quite confusing with "local currency".
Bitcoin, being a volatile and global currency uncontrolled by anyone, wouldn't suit these needs. A small local community would be at the mercy of global speculators who often decide to dump Bitcoin when they feel like it can't grow fast at the moment, and they would be powerless to stop it. But in case of their local currency, they can control it and maintain its value.
In my country Indonesia the currency remains the national currency and anything other than that is illegal and would be against the law.
They may be able to control the currency, maintain its value and keep it pegged to the value of the national currency so it will remain stable.
But when it comes to using Bitcoin, it will be a different thing.
We know that bitcoin fluctuations are very fast and are influenced globally, creating great volatility.
The use of Bitcoin is not just a currency for exchange, but also thinking about regulation and its impact on their economy.
