My understanding is that Ethereum has far too large of a user base to crash and not recover. There are many tokens on the Ethereum network and the Ethereum blockchain can acctually be used for something other than to prove transactions.

When OP made this post, Ethereum was crashing alongside Bitcoin, but the crash was due to a bitcoin correction. Probably in the future, Bitcoin wont hold so much weight over Ethereum and the prices wont synchronize as much.
