Anyone who is using the term premine with Dash clearly does not know the meaning of the word
premine and therefore should really look up the definition of that word. They make themself look
like a fool using that word.
You can use coinmarketcap to see which cryptocurrencies are premined, you will not find Dash
classified as premined there as it never was premined.
This seems an issue of semantics more than anything but even if the term is incorrectly used it does not change the reality that a significant amount of coins were mined in a very small amount of time the terminology does not change that.
