Not only that, but a local coin in the hands of local population and merchants that is used in day to day life will not have the problem of fluctuating and being that
unstable compared to coins like bitcoin, etherum, etc that are 99% speculative coins. Bitcoin can be 10.000$ today 2000$ tomorrow and 20.000 in 2 weeks.

A local coin functioning in a real economy will not have that problem. It will grow of course, but not in such a chaotic way as the big or other speculative coins because
the local currency coin will be backed up by real products/economics.
