I agree that an instamine isn't exactly the same as a premine but when 35% of the outstanding coins were created in one day that is highly significant. I'm not sure that one day gap really makes that big a difference compared to just issuing 35% of the coins in the genesis block. It's certainly worth noting somehow anyway.
By that definition, practically every PoS coin out there was "instamined". Most are 100% mined within a week. As long as they are pre-announced, that is fair. Dash was pre-announced and anyone could have benefited from the emission adjustment issue, not just the devs. And they did. I swear, if you spent half the time you spend trying to discredit Dash developing your own coin (Monero)...
Highlighting in red some proposed 2 million coin airdrop that Evan Duffield proposed to resolve the issue is deceptive (part of your "evidence"). That was a proposed 2m coin block that would be ADDED to the blockchain and distributed by Evan Duffield to the community and that proposal failed. The community hated the idea.
You guys need to move on. The coin was clearly not pre-mined. The first block was created after the announced release.
It's really rich coming from the guys from a coin with NO GUI complaining about how Dash launched without a windows wallet. The same guys warning the world about the "Dash scam" are the ones who are promoting their own coin that doesn't have a sustainable level of development and missed the promised GUI deadline by what, a YEAR now? Which coin requires a warning to investors? If it weren't so low class, I would be tempted to start a smear campaign against Moreno.
