As I'm understand that ARDOR could be traded soon after 12th Oct , how about the value? will be same price with NXT? or it's have starting price?
The starting price will be what the first seller and buyer agree to trade it for. There is no official starting price.
Will there be no market makers to start trading it? I think there should be because we cannot rely on the people. It might be a discouraging sight if there will be not enough volume for Ardor in the exchanges and it would look dead to the people outside this community.
It should be immediately available to trade on the Nxt Asset Exchange on October 12 hardfork. Everyone will be a market maker and can put the sell order for whichever price they believe it is worth. The free market will discover the right price very quickly as it always does. Centralized exchanges will list it too. We absolutely can and must rely on the free market, this is crypto.
