the 2 defitinions CMC currenlty use are both objective:
* - non mineable - Every coin states itself whether it is either mineable or not = true or false = objective
** - premine - Compare launch date to first block date to see if coins were mined before or after the launch = true or false = objective
Definitions are radial, and in common usage insta vs pre experience significant overlap. You are reaching into strict formal logic to justify hiding Dash's hideous early emission.
There is no consensus on exactly when Dash launched. Using that ambiguity to deflect from/hide the insta-premine is cynical and par for the Dash scam course.
