THE FACT BEHIND THIS METHODOLOGY IS THAT THE PRICE OF ETH SHOULD BE 1/17TH OF THE BITCOIN AT CURRENT CIRCULATION RATE
Supply is only one factor to determinate price. Much more influential factor is demand. If demand will decrease so will prices of any coin. That will happen when bear market hit. Same as happened in 2018. Supply was very similar in 2017 as in 2018. Prices was very different because of different demand.
