On May last year when BTC was around 8-10k marketcap was 450 billions and ETh was above 500 usd. And nowdays with the same BTC price ETH cost just 250 usd and marketcap only 270 billions... Seems we will see altcoins season soon 
That is most awaited thing everyone is waiting for this I also agreed with you the whole market is undervalue even now it is more advanced and have more adoption as compare with last year. I also believe very soon ETH will achieve this milestone so stay tuned.
Yes. Next hit is 300 usd if we break 277 usd. Volumes are increasing and this seems very positive for everyone. Probably the realist price of Eth in market value is between 400-500 Usd, so right now it seems understimated.
