Agree with you on Ethereum having some downward pressure in the short term as previous projects sell off. They will also need to sell more as they potentially need to raise cash for any SEC regulatory inquiries occuring (for legal fees). There will also be less demand as ICOs slow down due to regulatory uncertainty. However, the crypto space seems to be very adaptive and thus I would not be surprise for the Ethereum community to come up with scaling ideas and accelerate Dapp adoption. Ethereum has the brand recognition and will benefit from it in the long term.
