okay..  but what I am asking is: "How is the initial price determined when the coin is introduced to the market initially?"

Once it is in market, the relative supply, demand and (total marketcap)/(total coins in circulation) determines the price.

But "How is the initial price determined when the coin is introduced to the market initially?"

And also, there is NO ICO. So no initial money backing. Imagine that the coin is only distributed by airdrop and mining.

Thank you
