There will probably be another 2008 in the coming years.. that could have been that catalyst for btc in the first place. I get the feeling that another crash will only be a boon for crypto in general.
What I surely hope is that crypto will not be a casualty. The BTC plunge as well as that of all the other coins save for Ripple is definitely shaking a lot of people. People I know that bought in to this were visibly upset when they woke up to BTC down to $13,000.
