You are not factoring in the distribution that has already taken place and is continuing to take place.
Some people complain of dumping by early instaminers, others complain about 50% held by "instaminers" - like that percentage has remained static since day 1. But both accusations can't be true at the same time.
An additional source of irrationality is the price complain: If instaminers dump cheaply => then others can benefit by the coin distribution on the cheap. After all prices are lower than DRK mining costs (opportunity cost vs other coins). Yet the same argument is again used to say that the future price is doomed. How can all these be simultaneously true at the same time?
As I see it:
If instaminers are dumping, their percentage goes down and the overall distribution is improved.
If instaminers are holding, coin distribution remains as it is right now and price goes up due to very low inflation compared to other coins
If instaminers are suppressing the price below its fundamentals then its bad for the short-term price, good for long term price and good for fair distribution.
If instaminers are not suppressing the price then the price has great prospect for meteoric rise as demand escalates but also a questionmark for price suppression in the future if the bagholders sell.
We can't have "the coin is unfair", "instaminers have 50%", "instaminers are suppressing the price", "the price will always be low due to instaminers selling", "the coin will always be unfair because instaminers will (always) hold 10% of the coin" simultaneously. As you say, econ 101.
