But i`m very dissapointed about Ethereum, it`s very underestimated currency, almost all ICO`s are on ethereum blockchain, it should cost at least twise more.
Twice more than current price? What are you on? Ethereum is insanely overpriced already, and yet you believe it should be worth more?
Ethereum has performed exceptionally well this year, and managed to peak far, but really far above what it's realistically worth. I don't see any reason for Ether to have a value exceeding the 0.02BTC mark.
Bitcoin on the other hand, should see its price continue to increase, potentially to the $10,000 mark next year. If that turns out to happen, and the chances are definitely there, then prepare to see Ethereum tank even further.
Another important factor is that with more and more countries cracking down on ICOs, Ethereum is going to have that to deal with on top of the already decreasing momentum and sentiment.
