CoinMarketCap could easily put an end to this debate by changing the tag to "significantly pre-mined, insta-mined or ninja-mined". So my suggestion is to make this change.
This. Or alternately select coins that had a clearly scheduled release time publically announced say a minimum of 24 hours ahead of any mining, with coins subsequently emitted substantially in accordance with the originally published schedule. Filter the rest.
XMR should be included with this tag as well because of the scam mining software they released on launch. It is was purposely "de-optimized" so that the developers and insiders could mine at 100x the speed of the normal user.
Smooth and friends claim that this was an oversight or an accident, just like Evan claims the same for that launch of xcoin/dash. Same issue, same tag?
