It is possible that this reaching will happen but not yet. ETH can be called the altcoin which is the closest to the word stable in the market. Bitcoin exists a much longer in the crypto world and the ideas and technology of the blockchain are unique and they are constantly improving. Bitcoin has gained the trust of the investors long time before Ethereum even entered the market. I believe that when ETH will reach the market BTC price will rise much more and there will be new goals that ETH will try to reach. Its like any market… an incumbent (BTC) is sustainably improving its performance (aka value) over time, keeping its market (investors) happy whilst competitors (ETM) focus on disruptive innovation offering the customers (investors) of the incumbent (BTC) far more value (smart contracts) to surpass the market cap (share price) of the older incumbent (BTC).
