THanks for responding. I contacted support and they said this - is there no hope? :
"Unfortunately Coinbase is not currently compatible with any ICO, so your Coinbase wallet should not be used to participate in any ICO.
ICOs typically return tokens to the same address as the funds are sent from. Since Coinbase does not support those tokens, we are not able to credit an account with or return tokens sent to a Coinbase address.
Specific private keys associated with an address are not physically available to any single person. It would take a massive effort and some very large engineering resources just to access a specific key, not to mention the inherent security risks involved.
If you have already sent funds to an ICO address, unfortunately we will not be able to return any ICO funds or tokens that are sent to Coinbase-controlled addresses. I apologize, and wish there was something more we could do.
Unfortunately, digital currency transactions using most blockchains are irreversible, meaning once they are sent there is no way to reclaim funds.
