does duck note do anything monero does not?
I bought some a long time ago at 6 sat should I sell?
duckNote development is absolutely different comparison with Monero.
duckNote has its own absolutely unique features and duckNote GUI wallet is the only "light" and "heavy" wallet both working with 1 button click.
duckNote devs are working on High Level API and wallets and services based on it (there is one already), while Monero do not have Hight Level API at all.
