He makes a point. There is no stable working wallet since 2019 and rest development is look like mainteanace or half done projects.
Do not try to sugarcoat a project who stalled sinc. Igno times, during his time, developers has done most of the development of GRIN, after him everything gone south.
GUI is again eyewash as it before. I am sure it wont be finished like atomic swaps or mwixnet or hardware wallet or other things.
After igno, no serious development.Period.
Even grin++ developer bailed, the guy has warned core team guys many times about GRIN development issues.
