I'd like to see some up to date analysis on various stable coin implementations to see if Nu still has a niche to target, which is essential if it's going to recover in some form.
Tether is more centralised, but has huge volume & adoption, however the centralisation is a huge risk, as demonstrated by their recent banking issues that have wobbled confidence.
Not sure how BitUSD etc is doing, or how it compares to Nu.
MakerDAO sounds interesting (pegging to SDR).
When I have some time I'll try to do a quick survey of similar projects & how they compare, but at the moment it seems there isn't any decentralised stable coin with any significant following, which gives Nu an opportunity to aim for.
