Ethereum has still to address its scalability issues. I don't think ETH-BTC flipping is happening anytime soon, unless they address those issues.
While BTC also has issues, a platform coin the ETH should never ever display such performance problems. That is not the hallmark of a good product.
One thing a recent crash has taught to people is to not invest blindly into anything. I am seeing people are now doing more research, collaborating than they did in December and early Jan. Overall its good for the Crypto market. Such crashed only bring out quality products. I am sure there will be more such crashes in future and thats when quality projects will stand apart from crap ones.
