and that's why marketcap matters. If new tokens are released, they must find a buyer. If they cannot find it, they are dumped on the market, lowering the price. In most cases finally reaching the market cap before the issuance of new tokens. Marketcap shows how much the entire project is worth. The price of one token is only the marketcap divided by the supply.
So in 2019 NEO was a little more than 2x bigger than GAS. Now its 7 times bigger which proves that this is not the case at all that "people trading a NEO utility token GAS decided to believe in it more than native coin NEO".
In the long term, exactly the opposite is true.
