It is not only stable but also really high. More than $40 for quite some time now. I guess that by May it may become worth around $55 and stabilize there. I think those who say the price was/is pumped just underestimate this coin and don't think about it being quite innovative and open to further changes. So some day it may become as good as bitcoin is and in case btc somehow dies, eth along with litecoin will become the best one.
