Good for you, I imagine I might have been driven by FUD to close my position on ETH if I were invested at the time I heard this. I think the price went down about $20, down to around $280, if I recall correctly, and that might have scared me. But I think you are correct that any sell last night would have been panic selling.
I really expect ETH to continue growing and holding a big part of the market share, but I would say that this event does point out why Lisk could be a better project, in the long run. I say that because of the seperate channels that Lisk uses, which differs from Ethereum's protocol.
Do you hold any Lisk? What do you think of Lisk? I wonder whether people did buy Lisk following this Parity issue, because Lisk did kill it today. Thoughts?
