ETH is cheap right now and should be seen as a long term investment. Each day there are more and more new devs jumping into the Ethereum Eco system to develop DAO and DAPPS. And let's not forget the banking industries great interest in ETH.
eth is buggy incomplete software with no real world use. Why does this deserve a value of $12?? I think that eth is promising but for the current stage of development the price is to high. For this early stage a price of $1 - $2 would be more reasonable. Even if i wanted to try ether i would not pay $12 for a single coin thats just a deal breaker.
The entire Crypto space is new and buggy. You are in a sense doing the same as those who criticized the internet back in the day because there were not many websites and the post worked fine for them.
To value companies and these technologies now requires taking a chance and a lot of foresight.
If you want to wait for profits, p/e ratios, etc. you will be looking at the rocket leaving Earth orbit.
no risk, no win
