A friend was bragging to me about the merits of her local currency, but I wonder what's the point since we have bitcoin? Bitcoin which obviously includes the world population.
Local currency?, do you mean a country's local currency or each town or state having it's own currency?, Yes there are benefits of having local currency since you aren't only limited to bitcoin.
Local currency payment is instant-
For example, you're paying at a restaurant where you need instant payment rather than waiting for Bitcoin transfer (which can take up to an hour sometimes if you are unlucky)
I did not really understand the objectives of these local currencies, I was wondering if local currencies existed in other countries and if people understood the interest of these local currencies which seem to undergo inflation like the fiats.
Local currencies are fast in transaction compared to Bitcoin so I'm sure there are reasons people prefer both Bitcoin and local currencies (Look at a common example i presented above)
