Being a cryptocurrency-skeptic I won't pretend that I don't experience a little bit of schadenfreude when I see CC crash, however if I'm trying to be a bit more constructive I suppose that means that we're nearing the "make or break" point: if the huge investment in cryptocurrency-related technologies over the past four years or so manages to produce something actually useful over the next year I have no doubt that this is only a temporary set-back and we'll see BTC (or some other coin) breach $20k again.
On the other hand if, like I believe, it's mostly scams, empty promises and poor understanding of technology and/or economy, then this might be the beginning of the end. Hype can only sustain a $100 billion market cap for so long. That being said I wouldn't be the first Pythia to erroneously predict the downfall of cryptocurrencies...
