Another thing is that Ethereum has had almost no major exposure to the ordinary, middle class folks. Sure people know about bitcoin, but Ethereum could use the PR work Bitcoin has done and do a leapfrog. I would imagine ETH going to 500+ with the coverage BTC is getting. FOMO is another thing too
ETH can be more powerful than bitcoin, but it's not powerful enough and the potential for government recognition is still a fledgling currency. Its development is like all other altcoins, its value is not stable. If it wants to compete with bitcoin, it's still not powerful enough. It takes more time.
