Where are these "local communities" that mine obscure cryptocoins but don't even know about btctalk?
DarkNote is 31st out of the 500 coins on CMC, which hardly qualifies as "obscure."
Those "local communities" are probably in areas where English isn't a popular language.
Doge brought crypto to vast, entirely new, demographic swaths and DuckNote appealed to the same groups.
You do realize there are four billion people in Asia and Europe who don't GAF about this Anglocentric forum and have their own forums, right?
