We really wont know the value of ETH until they implement Proof of stake prove it works. Smart contracts are usefull but i think they will just be implemented into a more secure and organised community like DASH.
PS ETH is spiking now, so buy up before its 2 late
Its not good to buy right now because the price of eth right now is high even we are seeing that the price is increase better to go timing when you should buy ethereum so that you can be lose a lot or you can make more profit.
