We can build projects on ETH and it is not just transferring money coins. So I think $5 is a far low goal for a projects like ETH. Though it can't replace BTC now it's still better than BTC technology wise.
I agree about the technology concept. I has been more than a decade since the launching of Bitcoin and ETH was launched just few years ago and if we compare both, ETH looks a bit more stable under its lower value than Bitcoin but again Bitcoin being the top coin having the highest market cap has the influence on the rest of the market and can affect ETH. So ETH has to follow the rise with Bitcoin.
